I know this question has been asked before but i can't seem to see from the other posts what this could be i don't know asp i have just been uploading images and changing the database and re uploading via FTP but now i have come across a error
Provider error '80004005'
Unspecified error
/Includes/DB/DatabaseConnect.asp, line 8
<%
Dim espostiDB
Set espostiDB = Server.CreateObject("ADODB.Connection")
'espostiDB.ConnectionString = "DSN=esposti.dsn"
'espostiDB.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Server.MapPath("db\esposti1.mdb")
espostiDB.ConnectionString = "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" & Server.MapPath("db\esposti.mdb") ')e:\inetpub\wwwroot\esposti\esposti.mdb"
'espostiDB.ConnectionString = "DSN=esposti.dsn"
espostiDB.Open
%>
line 8 is espostiDB.open
Database is Access 2000
Help Much appreciated

This is how I solved this problem, the exact same error. Went to Control Panel - Administrative Tools - Internet information Services. On the right click View Application Pools and for both "Classic NET AppPool" and "DefaultAppPool" set v4.0 network framework version. If it's set to v2.0 the error above will show up.
Working with your code above, you could use this:
<%
Set espostiDB = Server.CreateObject("ADODB.Connection")
connStr = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Server.MapPath("~\db\esposti.mdb")
espostiDB.Open connStr
%>
The info here will also give you some pointers of how to work Server.MapPath (in case your mdb file is not in the root of your website).
80004005 errors can be numerous things, one thing to check is that the database is not currently in an open state and therefore locked, so every time you open a connection you need to make sure that you close it. An easy way to check this is to check if there is an Access lock file (.ldb) file in the same folder as the database.
Check that you've not inadvertently changed the path so it's now incorrect (a Response.Write(Server.MapPath("db\esposti.mdb"))) should print the full path.
Also, worth recycling the IIS app pool, sometimes connections remain open in IIS and the database becomes unresponsive, this can be a sign you're not closing connections properly.
The cause of this conflicts looks to be 32 Bit Application running on the 64 Bit. Please make sure that the ODBC connection is described at C:\Windows\SysWOW64\odbcad32.exe

I have used the code below to open a SQLite database file that sits on a network computer for more than a year now almost on a daily basis. Suddenly this morning, I am not able to open the file programmatically.
private Boolean Connect(String strPathFile)
{
// Initialize the connection object.
this.DbConnection = null;
try
{
// DATABASE: Create the connection string and set the settings.
String strConnection = #"Data Source=" + strPathFile + #";Version=3;";
// DATABASE: Connect to the database.
this.DbConnection = new SQLiteConnection(strConnection);
this.DbConnection.Open();
return true;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
return false;
}
The file is a network resource in the form "\Server\ShareName\FileName.db" (less the double quotes).
Here is the interesting thing. SQLite Administrator has no issues opening up the network database file, none, and repeatedly. I can also open up the file locally. I copied the file to my local drive and simply changed the path inside Visual Studio 2012 (VS2012).
The server seemed fine. It had gone through a reboot at some point since the last time that I checked on it. I presume a Microsoft Update. File Explorer has no issues browsing the folder, and as I said SQLite Administrator can open the network file.
I checked once again on permissions and everyone has full control as well as the server's users have full control, both on the security permissions and on the share permissions. I checked the folder and file, and permissions are the same. I expected as much, because SQLite Administrator can open the file. The server does not have a firewall set up, Windows Firewall or otherwise. I rechecked that this morning as well. Again, SQLite Administrator would have complained about that.
I verified writing, by making a copy of the file on the network drive using File Explorer. That had no issues.
The sever is a Windows Server 2003. I am using Windows 7 Professional 64-bit.
I also tried to open up the database in read only mode, but that failed as well. I was expecting that behavior. SQLite Administrator still works nicely.
I tried various other connection strings including SQLiteConnectionStringBuilder() just to see what happens, and all roads lead to Rome, namely:
System.Data.SQLite.SQLiteException occurred
HResult=-2147467259
Message=unable to open database file
Source=System.Data.SQLite

Double the leading two backslashes in the file name
(e.g. "\\\\network\share\file.db").
Use a mapped drive letter.
Use the SQLiteConnection constructor that takes the parseViaFramework
boolean argument and pass 'true' for that argument.
See the SQL post here
Assuming the db file is accessible (e.g. "because SQLite Administrator can open the file"), then option #2 from the answer by ranmoro and GEEF seems to work. This becomes:
bool parseViaFramework = true;
con = new SQLiteConnection( cs, parseViaFramework );
in code. The rationale is discussed in the SQLite check-in comment "mistachkin added on 2013-05-25 21:06:45" in https://system.data.sqlite.org/index.html/info/bbdda6eae2
My connection strings are of the form:
URI=file:\\SERVER\Data\SqlData\History.db
for UNC paths, or
URI=file:C:\Data\SqlData\History.db
for local paths.
I am using:
Visual Studio 2022
<TargetFramework>net5.0-windows</TargetFramework>
<PackageReference Include="System.Data.SQLite.Core" Version="1.0.115.5" />
I had a similar issue. Replacing the UNC (\server\share\folder\file.db) with a mapped drive path (S:\folder\file.db) resolve the issue in my instance.
The error message is very misleading + irritating. Applications working fine in the local environment get failed to start in client server situation.
It has mostly noting to do with the code. Its related to server side.
Make sure the Write access is available for the server folder containing the file.
UNC [IP based server path] is not supported still, the network path/folder should be mapped to overcome this issue.
Some sites+users are saying to mention the Version No. in the connection string. All my applications are working fine without using it.
Connection String:
Data Source=[Mapped Server Location]\[SubFolders]\[FileName].db;
Update:
I tried to prepend \\ to the UNC path and it worked (added additional \\ in the beginning only, not in-between).
Data Source=\\[UNC]\[SubFolders]\[FileName].db;
Server is dedicated and I have remote access.
We have custom ASP CMS with Access database and we use custom error pages for "mod rewrite". It works great.
This website is available in 6 different languages and each language has its own domain and they all connect to the same database.
Problem is, I get this error every few hours:
Microsoft JET Database Engine error '80004005'
Unspecified error
After I get this error I have to restart IIS or edit "Error pages settings" to detailed error and then set it again to custom. After that it works fine.
I have Process monitor installed and I track w3wp.exe proces.
When error ocurs I got Access denied on HKLM\SOFTWARE\Wow6432Node\Microsoft\Jet\4.0\Engines.
Thank you.
Access database was never built for high volume traffic, most likely it just crash due to sheer amount of requests.
You really better switch to real databae, these days you have great many for free including SQL Server Express, MySQL and lots more.
In the meantime you can go through your code and make sure you:
Always close the Recordset right after using it then Setting it to Nothing e.g.
Do Until oRS.EOF
'do your stuff...
oRS.MoveNext
Loop
'Always close after use
oRS.Close
Set oRS = Nothing
Same for Connection object: close and dispose when you are finished with it.
Many times pages use Redirect - make sure to close and dispose before redirecting e.g.
If oRS.EOF Then
'Always close after use
oRS.Close
Set oRS = Nothing
Response.Redirect("Error.asp?v=nouser")
End If
'do your stuff...
'Always close after use
oRS.Close
Set oRS = Nothing
Firstly, I know that there are a lot of similar topics, but none seem to solve my problem.
I have inherited a project where the front-end is built in ASP.NET and the CMS is built in classic ASP. I'm in the process of setting up a local development environment where I've copied the database from the live server and am configuring the website to connect to my new local DB.
The ASP.NET part is connecting with the connection string Data Source=.\\SQLEXPRESS; Database=DBNAME; Trusted_Connection=True; but I had to mess about with Application Pools and Permissions.
I'm having a problem with getting the classic ASP part of the website to connect to the SQL database. The error I am recieving is:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database "DBNAME" requested by the login. The login failed.
/cms/connections/Conn.asp, line 18
The code in that file is:
12. Dim Conn_STRING, URL, mailHost
13. Conn_STRING = "Driver={SQL Server}; Server=.\SQLEXPRESS; Database=DBNAME; Trusted_Connection=True;"
15. Dim conn
16. set conn = Server.CreateObject("ADODB.Connection")
17. conn.ConnectionString = Conn_STRING
18. conn.Open
I know it's a permission problem or some sort, but I can't get to the bottom of it. I'll appreciate any help at all :)
hmmmm, well, the asp.net part is using SQLExpress, connected via an attached file. DBNAME in the first example is going to refer to a db file name in the actual asp.net project. It's been quite a long time since I last used classic ASP, but I'd be STUNNED if it supports this. You need to attach the db file to an actual sql server and use it that way.
server=mycomputername\sqlexpress; database=DBNAME; user id=username; password=password
You'll need to open your database in sql express mngmt studio
http://www.microsoft.com/download/en/details.aspx?id=7593
Go into your security settings for that user and set the default database to "dbname" (whatver your real dbname is of course)
Ensure your app pool is set to run under the user that has permissions to that database. It may just be easier to enable mixed mode authentication and create a sql user to connect to the database rather than messing around with windows authentication on an app pool.
You wil lof course need to change your connection string then to support the sql authentication if you go that route.

I am new to ASP. I have two databases production and developer databases.
I need to check developer site is going to developer database or not. Both databases have same data and same table names.
But i must work on developer database only how can I?
Generally you'd have an environment configuration file. If you're talking about ASP.NET then it would be the Web.config file. If you're indeed talking about classic ASP then it would probably be an included script with some constants.
If the databases are structurally identical (which they should be) then all you should need to change is the connection string. For classic ASP, you'd probably just store it in a variable:
Dim connString = "This is your connection string"
On the production server, the connection string would be set to your production database. On development machines, it would be set to a development database. (And so on for a test environment, etc.) All of the data access code would just use this connection string variable.
Even more to the point, this should not be the only thing that prevents a developer from using the production database. The DBA should set the permissions such that only the production application has only the access it needs to that database and others do not. Developers should never be able to accidentally modify the production database. So even if you did use the production connection string from your workstation, the database should simply deny you access.
Have two connection strings. Then create a constant variable which will act as your switch and pick the correct connection string:
Dim strCon
CONST DEVELOPMENT = true
if(DEVELOPMENT = true) then
strCon = "Development connection string"
else
strCon = "Live connection string"
end if
adoCon.open strCon
Then you can simply change the switch to true/false depending on which database to pick.
When you specify the database connection you know where you are pointing, so this should be straightforward. But it might be a good idea to use separate logins on dev and production.
So the answer is that you should use the connectionstrings in the config files to get what you need: the "database =.." setting should be set correctly and your problem is aolvedsolved To get extra certainty use different logins, which is recommendable in any case.
you can also use server tracing to monitor activity, but it is not easy on a multi user database and is only a diagnostics tool, not a cure.
I have Oracle 10g and have installed ODBC via the instant client. I am able to use the ODBC administrator and set up a DSN and test successfully, and whenever I use Microsoft Access I can connect to my database no problem. I can also use Visual Web Developer to traverse the data.
But, when I try and use Classic ASP with:
myConn.Open "DSN=oracle10g;" & _
"Uid=myOracleUsername;" & "Pwd=myOraclePassword"
I get:
-2147467259Specified driver could not be loaded due to system error 5 (Oracle in instantclient10_2).
An error occurred while trying to create Server Object.
I have searched various places but nothing seems to work. All ORACLE_HOME, TNSnames, IUSR_X security, all is correct. I am thinking it is a DSN connection string problem.
Anyone know?
Try using the following DSN-less connection string:
myConn.Open "Provider=MSDAORA;Data Source=instance_name;User ID=myOracleUsername;Password=myOraclePassword"
I've used this exact connection string for older version of Oracle client, but can't see any reason why it won't work for your version as well.
try this :
provider=OraOLEDB.Oracle
