Cannot Start IIS on my PC: COM+ System Application: Access is Denied - asp.net

I'm trying to do some web development. I cannot start IIS (I need to run some Web Services).
As of about a month ago, the "COM+ System Application" service has started failing with this error:
The COM+ System Application service
failed to start due to the following
error: Access is denied.
DCOM also logs an error in the event log:
DCOM got error "Access is denied. "
attempting to start the service
COMSysApp with arguments "" in order
to run the server:
{ECABAFBC-7F19-11D2-978E-0000F8757E2A}
When I start IIS and the WWW service, everthing seems to work until I hit port 80 on my machine at which time the IIS/WWW services both crash unexpectedly:
The World Wide Web Publishing service
terminated unexpectedly. It has done
this 1 time(s).
The following event is placed in the application log as well:
The run-time environment has detected
an inconsistency in its internal
state. This indicates a potential
instability in the process that could
be caused by the custom components
running in the COM+ application, the
components they make use of, or other
factors. Error in
f:\xpsp3\com\com1x\src\comsvcs\package\cpackage.cpp(1184),
hr = 80070005: InitEventCollector
failed
I have searched google until my fingers are numb. I've searched this site to no avail as well.
I have tried:
running the COM+ System Application service as an administrator.
reinstalling SP3 for XP
giving the "SERVICE" account full control to %SYSTEMROOT%\Registration
removing XP Security hotfixes installed about the time it stopped working
I've removed and reinstalled COM+ (it's possible, check google)
Any insight on the COM+ subsystem, it's files and settings or just how it operates would be greatly appreciated.
I need to get this problem resolved so I can get back to work.

Have you seen this link?

I'm having the same problem, and it appears it might have fixed it for me - though I did have to reboot afterwards which isn't explicitly in the kb instructions.
(Though it's hard to tell right now if this actually fixed it, because sometimes for me the problem would disappear on its own after a reboot (which doesn't make a lot of sense given the steps in the kb)).

Sorry all.
I forgot to update this when I found the solution... Well, it was self-inflicted. Some months ago, I removed the execute permissions from dllhost.exe. I hadn't been coding asp.net web apps at the time so I didn't notice the problem and couldn't put two and two together very quickly.
I eventually found it by turning on file system failed auditing on my Windows folder hive. I saw a mess of access denied messages related to dllhost.exe and remembered what I'd done.
Thanks for the help.

IIS 10.0 AppPool crashing (causing 503 error)

Situation
After the latest Windows 10 updates (Nov 2017) were installed, the Application Pool required by a local web application keeps stopping/crashing displaying the message below in Event Viewer:
The worker process for application pool 'SrvAppPoolv4.0'
encountered an error 'Cannot read configuration file ' trying to read
configuration data from file '\\?\<EMPTY>', line number '0'. The data
field contains the error code.
Setup
Windows 10
Internet Information Services (Version 10.0.16299.15)
What I've tried
I've tried a few things that I've found via Google, both here on Stackoverflow and other sites, nothing has helped so far. Some of what I've tried:
Changed the AppPool Identity to a different user (Right-click, Advanced Settings).
Checked the permissions on the machine.config (all four of them in the various \Windows\Microsoft.NET\Framework\.. and ..\Framework64\.. folders).
Unchecked the IIS and .NET features (Control Panel / Windows Features) and then added them back in again.
Uninstalled the application in question, cleared everything, then re-installed it.
Nothing has helped.
Besides reinstalling the entire machine, what else can I try?
Also, besides the Event Viewer, are there any other logs I can review to get more details? I read something about an application log, but nothing as to where to find it?
Update:
I just tried what user3739842 suggested Add/Remove Programs, selecting IIS Express and then Repair - issue remains.
Solution
For me the solution was the following (thanks rusware):
Go to the drive your IIS is installed on, eg. C:\inetpub\temp\appPools\
Delete the directory (or virtual directory) with the same name as your app pool.
Recycle/Start your app pool again.
In my case, it was a virtual directory which was corrupted.
Hi the answer to your problem can be found here. It worked for me and same error
Cannot read configuration file ' trying to read configuration data from file '\\?\<EMPTY>', line number '0'.

IISRESET windows 10 (IIS 10) Access denied

I'm just wondering, why I get error during an iisreset in my development machine.
When I execute the command in a Command Prompt some times it wokrs,sometimes it throws an Access Denied Error, and sometimes it throws a file not found exception.
If anyone finds a solution to this anoying problem, I would appreciate a hint how to get rid of it.
In the IIS I'm just hosting an .NET 4.6.1 MVC site.
This stupid error happens randomly and was very annoying especially when you place iisreset inside a script and assume it will do its thing; took me a while to figure it out. It is not related to the service being stopped as can be seen in this picture:
The only thing I use now is:
net stop W3SVC
and
net start W3SVC
Haven't had a problem since then.
I got exactly the same error time ago. Running it in German too. Take a look at this article: https://techcommunity.microsoft.com/t5/iis-support-blog/iis-reset-issue-restart-attempt-failed/ba-p/1031976
Judging from #Giorgi Nakeuri's question about the event logs. The "World Wide Web Publishing" (called only "WWW-Publishingdienst" in German) is very likely not running. You need to start it. The "Windows activity process service" fails because of the first one failing.
I think it says that he was unable to start the service, mainly due to a Problem with authorization. The solution of the problem can be provided in several different ways
1- Configuration causing the authorization error can be corrected
applicationHost.config with XML
2- This authorization can be revoked through the Windows register. Example approach here:
https://stackoverflow.com/a/21036837/914284
3- Machine configuration can be changed in accordance with this
permission. Please continue with the option that suits you :)

i hope it will resolve
Specifying the machine name also helps in some scenarios:
iisreset %ComputerName%

Java/Websphere NoSuchProviderException: IBMCertPath

I've recently inherited a task at my company that involves implementing an application that has currently been running off an employee's windows desktop, and migrating that code to Unix Server used for the office.
The server also runs IBM's websphere, which contains many of the companies larger web applications and uses java 1.6.
Organizational points aside (this is a huge company and much of the coding looks like a spaghetti western, with old legacy systems I wouldn't be suprised if people don't have any idea about), my plans was simply downgrade the code (which was simple as it was from 1.7 to 1.6), then move this application to a runnable jar, and call it via a shell script.
I, however, realize now why this application was never migrated to our production server, as I can't get the thing to run in the UNIX system.
First, I ran into an issue where (and I may be wrong about this) the SSL connections used as part of the application throws an error (same error as this question: Error accessing a Web Service with SSL) After some reading, it seems that any java application run on a server with Websphere (if the application is not in websphere) cannot be done, and thus you have to manually set some java Security Properties to do this (which i did right at the opening of my main method).
After doing that, I get past the initial error, but I am now getting this error
"com.ibm.jsse2.util.j: PKIX path validation failed: java.security.NoSuchProviderException: no such provider: IBMCertPath"
If this has already been asked, I'm sorry, but I couldn't seem to find it. Please link it here and i will close the question.
You are getting the error because something has specified to use the IBMCertPath provider, but java security doesn't know what that provider is.
You need to ensure that com.ibm.security.cert.IBMCertPath is in the provider list in your java.security file. See:

ASP.NET web application can't find an assembly

I deployed an ASP.NET web application last night and I when I woke up this morning it was very slow and would occasionally just throw a 'Service Unavailable' error.
I checked the Event Viewer and it was filled up with these errors:
An unhandled exception occurred and the process was terminated.
Exception: System.Runtime.Serialization.SerializationException
Message: Unable to find assembly 'MonoTorrent, Version=0.80.0.0, Culture=neutral, PublicKeyToken=null'
I'm puzzled as it was working perfectly when I deployed it (MonoTorrent is required to retrieve the number of seeders/leechers for a certain torrent off the tracker - this was working fine), but it's no longer working and whenever code that uses MonoTorrent gets involved, the worker process just crashes.
MonoTorrent.dll is in the /bin/ directory.
UPDATE 6/4/10: I compiled the MonoTorrent source code in with the rest of my web application, but it still crashes whenever it uses MonoTorrent. However, it now says that it is Unable to find assembly 'OpenPeer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null. Here, OpenPeer is the name of the web application's assembly.
This can happen in these circumstances:
The ASP.NET app creates a background thread, which throws an uncaught exception. It looks like ASP.NET catches the exception and wants to log it to the Event Log. To do this, it sends this exception from the Web app's app domain to its own app domain (the default one of the w3wp process). This needs a serialization/deserialization of the exception.
If the exception is a custom one (i.e. defined by the Web app), it cannot be deserialized in the main app domain of ASP.NET because the assembly defining the exception is typically in the Web app's bin directory, not where w3wp.exe is (c:\windows\system32\inetsrv). This causes a serialization exception and w3wp crashes.
There are possible ways to fix the issue (in a - very subjective - order of preference):
Copy the missing DLL in c:\windows\system32\inetsrv
Install the missing DLL in the GAC
Remove the cause of the exception (harder to do than to say, as we say in French)
Catch all exceptions from the background thread yourself and do the logging yourself.
Notes:
If WCF is used and the uncaught exception is FaultException, WCF swallows it and there is no crash
If the uncaught exception is in the thread of the Web request, there is a yellow screen of death, not this serialization exception
It really seems like a bug in ASP.NET
The above is actually a summary of my investigations of this issue yesterday and are only a theory. I tested fixes 1 and 4, as well as using FaultException.
Here are some things you can try..
1.) Flush ASP.Net Temp directory. Restart IIS and recycle Application pool.
2.) Make sure your web-application is running in FULL-TRUST if it really needs FULL-TRUST.
3.) Take the Assembly, try to use it in other asp.net application and run the test application on a seperate server. This might help you diagnose the problem. Also try to run the test asp.net app on the same server but in seperate application pool.
4.) Make sure the IIS website of your application is running under the user account with necessary security priviliges. Try running the application under Administratotr as user.
EDIT-1
5.) Also check if the assembly version is the same as mentioned in web.config. If there's a version mismatch then you can do AssemblyBinding Redirection in web.config.
6.) Also try registaering the Assembly in GAC and see if it loads properly.
EDIT-2
7.) Try reconfigring ASP.NET support on the server or maybe framework runtime re-setup may help. This may not be a sure-shot solution but looking at the problem condition we may want to try various solutions.
8.) Make sure you're not missing any critical update of your windows server platform.
I try to give you some ideas - what I do if I was on your position.
First of all I take a long look of the MonoTorrent.dll before some days that you make your question, and I look it again today. I found and the function that load the dll. My first opinion is that something have to do with the permissions.
I hope that you have access to the server - right ?
My first steps is that:
Ensure that your monotorrent.dll actuall have the right permissions to the bin directory, for Read, and execute by your asp.net app. Some times the copy of one dll, did not get the directory permissions buts carriage out his own permissions. To check if your dll have different permissions from the rest, just right click and see Properties | Security, then go to bin directory and do the same, and compare the Security permissions. If they are different then apply again the Directory permissions and make sure that the dll inherited by the directory.
My second step
Download the ProcessMonitor from sysinternals
http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx
Run ProcessMonitor and try to recreate the error, stop it and analyse to see where and why the dll gets the denied permissions to run.
With the ProcessMonitor you can even see if there is any dll that can not found !
I have check the MonoTorrent dlls and I do not found anything unusual. He have kerner32.dll calls, and use unsafe code to run, ok nothing so special about.
So if you do that 2 steps and give me some feedback, maybe I can go further. (if not solve by you and what you find)
I would advice to setup Regular maintanence probably once in a week at sunday night etc for following,
Delete all temporary files
Delete all ASP.NET IIS temporary files
Restart Server
Problem is, ASP.NET web apps cause lot of temp files to be left in the disk, because of dynamic compilation of regex, seriliazation assemblies etc, such temp stuff never gets deleted, and more and more junk starts getting collected in temp locations, ASP.NET goes slower and slower, and a point comes in where disk as well as memory defragmentation reaches very high point, things start to fail.
No body likes to restart server once a week, but I remember we had no choice, in ASP.NET 1.1 we had stable system after restarting every day, in ASP.NET 2.0 onwards, we are good to have restarting scheduled at once a week.
I have found this problem and I have do all of thing as I can, such as clear temp file, restart server, delete and add reference and I also rebuild the solution. However I can't solving this problem. Finally I move my entity class (almost of them need to serialize) to new folder that I have added to the project and then this problem solved.
This method is work for me.
Try clearing the ASP.NET temp files. It's solved some odd issues before for me.
Otherwise, Fusion-logging may shed some light.
UPDATE: #Charlie - I'm not sure what to make of those logs...it looks like the failed log is from a different AppDomain. Notice the AppBase is set to "file:///c:/windows/system32/inetsrv/" and AppName is w3wp.exe.
I'm pretty sure the Event Viewer should show Application Id: LM/W3SVC/#/ROOT if it was the default AppDomain, too. At this point, all I've got is random guesses.
I notice you're running x64...does MonoTorrent perhaps require x86?
Have you double checked that the directory is an IIS application, and is configured for the correct version of ASP.NET?
Is there some other application that uses MonoTorrent on this server? Maybe a WCF service or something? I'm not sure where the Serialization is happening....
Try hooking the AssemblyResolve event and loading it manually.
Can you repro on a development machine? If not, maybe it's a borked FX install. Uninstall and reinstall.
Does restarting, recycling or stopping/starting the AppPool fix the issue temporarily, or cause the issue to appear?
You may want to type out your screenshot text too so you'll get some Google love....
Is the server timezone different than your timezone? I've had this issue when deploying resource files, the compile time was in the future so they would fail to load.
My guess that you have plenty of open but not closed connections. I mean the connections are not returned to the pool. It looks okay, when you start the application, but after some time there are only several sockets available in the pool and it goes slow. Another thing - non-closed connection may keep DLL in memory, not allowing to release the handler. Try to debug object destruction.
I know it's simple but I had this problem once and itwas because I had a Web Application project which contains
References
Folder and I just copied my files into a
Bin
folder, in any .net web application in the Project Properties windows, a Reference Path tab is available which by default should nothing be include on it. check this option and also Build tab in Project Properties window which Output path be as the same as bin\

DotNetNuke 3.0.x on SQLServer 2005/Net 2.0.Win2003 - possible?

I've promised to take a look at an old DotNetNuke installation for a client with the intention of making a few, hopefully minor, changes. The installation is rather old - I believe version 3.0.013 - and the production copy is running against SQL Server 2000, Windows 2003 and .Net 1.1.
As the production server is live and significantly used we need a development installation first. I have attempted to install a copy on my local server - Windows 2003, SQL Server 2005, .Net 2.0, and although with a few tweaks I can successfully get it to display the site, I cannot login, or even access the login module (ie just putting in blank username and password attempting to generate a 'must enter username' type error) without getting the error 'Object reference not set to an instance of an object'
I've spent some time trying to get around this error, without success, although I am hampered by not having used this package before.
So my questions are
Has anyone managed to run DotNetNuke 3.0.x with this configuration (or do I need to setup a box with SQL 2000 and .Net 1.0 to get it to run)?
Any suggestions where I should start looking for this error, or has anyone come across anything similar before?
EDIT: Eventually chickened out and installed in on an old webserver with Win2003/SQL 2000/Net 1.1 and it went in fine on an identical install. So I guess the answer is no, it doesn't work straight out of the box.
My feeling is that you shouldn't have any trouble running in the above mentioned environment. But taking a closer look at the error itself will help us to prove that.
If the error is occurring only when you navigate to the Login module, it may be an issue loading the authentication provider. The best way to find out is to look in the DNN Event Log and take a look at the full error message.
Because you can't login to access the Event Log, you should probably just take a look at the row created in the database when you receive the error. The table is called EventLog and there may be a little bit of friction in parsing the error message out, as all of the details are stored in the database in an XML format.
In general, when moving a site from one environment to another there are only a couple of things that you'd need to do:
make sure you can connect to the database
set the file system permissions
It sounds like you already have database connectivity because you can load the site.
However, you may want to double check (just re-apply) the file system permissions for the root of the website on the machine in question. Make sure the identity of the website (typically ASP.NET Machine Account or Network Service) has 'Modify' permissions on the root website directory. Perhaps the web site can't load a particular assembly due to lack of permissions.
