I have added the user ASP.NET Machine Account (\ASPNET) to the directory where the files are (which is the same as the app)
When you run a webapp in IIS, it is the user that the AppPool runs under that matters.
This varies, so check out the settings IN IIS, and assign permissions for this account instead to the relevant folders.
http://www.advancedinstaller.com/user-guide/iis-app-pool-identity.html
Clearly this is a permission issue. If you are certain the ASP.NET account is configure correctly then are you doing any identity impersonation in web.config i.e. <identity impersonate="true" userName=... and if so is this account configured correctly?
It seems like that your application is trying to access file(s) in the failure. Are you sure you gave the app write/read permission for the file in IIS?
Late response but was back looking at this site and though I should update for anyone with similar issues.
Yes this was a permissions issue. As mentioned by Barry I needed to impersonate the logon for the server account to access temp dir's etc.

I almost hate to ask this since there seem to be piles of variations of this question, but thus far none have helped.
I am trying to stand up an old ASP.Net 2.0 app that worked fine a few years ago (different computer/environment.) I can get the default/main page to display without issues. However, all database calls fail. I can connect to "(localdb)\MSSQLLocalDB" via SSMS (either with windows auth, or the intended app credentials.) Select statements run via SSMS on all tables/views/sprocs without issue (all are thus far empty, but they exist.)

These are the events from a single attempt to hit the page/db. The warning is the same message/exception listed at the top of this post. The SQL error (not too helpful) is repeated all five times (and are as follows.)
Troubleshooting steps
Deleted and recreated DB
Deleted following path items,
C:\Users\myuser\AppData\Local\Microsoft\Microsoft SQL Server Local
DB\Instances
Disabled Firewall to ensure it was not the problem
Recycled/restarted app pool and web site (numerous times)
Set and loadUserProfile and setProfileEnvironment to true in this file, C:\Windows\System32\inetsrv\config\applicationHost.config as indicated here
What on earth have I missed?
I'll leave it to the community if this is worth keeping.
The problem is now resolved, unfortunately, I don't know exactly which step resolved the issue.
I did notice just recently that deleting and recreating the MSSQLLocalDB entry via sqllocaldb.exe dropped access to the application's DB needed (along with its tables/views/etc.) This was odd because, when I tried to recreate it, SQL complained that the db.mdf file was already in the C:\Users\myser folder. I deleted the MDF and LDF files there, and then just recreated the db (contained user, tables, views, sproc) and all is finally working.
Ugh, several days of work later. No offense taken if the community feels this post is extraneous (but perhaps the collection of troubleshooting steps might be worthwhile for others.)
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.
Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .
if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .
if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .
after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).
if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.
If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.
If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.
If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.
Restart your sql server instance after making any changes in property as some changes will require restart.
if you further face any difficulty then you need to provide more information about your web site and sql server .
i am porting a web application to aws. there is an aspx page that collates info from about 15 or 20 different tables data tables from 3 different databases. it is running fine on godaddy shared hosting and also on my dev servers but when i put it on a micro instance ec2 on aws (not sure if that has anything to do with the problem just trying to give as much info as possible) i am getting random errors. i works sometimes but quite often i am getting the following error

sometimes i get a different error that says something to the effect that the connection is already closed.
this is super weird because i have no problem with the site on the shared hosting or on my dev server. the aws machine is running windows 2008 server and iis 7.5 and sql server express 2008 r2. there are other pages in the site that use data tables just fine and never have this error but they are using less less data tables. anyone have any idea what could be causing this?
I think you are hitting the micro instance's 613MB RAM limit. It's probably not enough for Windows Server, IIS, and SQL Server together. A couple of things you might also try: disable connection pooling in the connection string; also, make sure you immediately dispose your connection as soon as the command completes (use using blocks).
I am supporting an ASP.Net 3.5 web application and users are experiencing a timeout error after 30 seconds when trying to run a report. Looking around the web it seems it's easy enough to change the timeout in the code, unfortunately I'm not able to access the code and recompile. Is there anyway to configure the default for either the web app, the worker process, IIS or the whole machine?
Here is the stack trace up to the point where it's in System.Data in case I'm missing some other problem:

--Edit
There must be something outside the code itself - I've downloaded the database and run it against the same web site installed on a test server and it runs for longer than 30 seconds and returns the report. I've compared the machine.config and web.config files from the .Net directory on the live and test and they seem the same, compared the two IIS setups, also looked at the SQL Server configuration and the only difference is that the live server is clustered on 64bit W2K3 while the test server is on 32bit.
Unfortunately, everything I've read about this in the past says no, can't be controlled via configuration. Which is a bummer.
You cannot set the command timeout from the connection string or some external setting, sorry.
Sometimes a driver will interpret the 'timeout' parameter in the connection string as both Connect Timeout and Command Timeout period, but that is technically a "bug". Gotta love the standards.
The best I know of is you can set a Connection Timeout in the connection string which controls how long ADO will wait while trying to connect to SQL Server and doesn't impact the Command Timeout.
Personally I think there should be a way to change this setting. Assuming the assembly this is in is not strong named your best bet might be to reverse engineer the code modify the source and redeploy the assembly with the new name.
It's not too hard to roll your own though? Just create a custom SqlCommandTimeout setting under AppSettings. If you are already using some sort of SqlCommandFactory to create your SqlCommand or have some sort of SqlCommand base class then you can easily make the change. If not then you probably don't care enough about your code to want to put this in a configuration file anyway.
