System.Data.OleDb.OleDbException: Unspecified error

[DOTNET]

Hi all,

I have written code for connecting Access database and it worked fine and in
one fine morning the database connection command gives the following error.
I searched in MSDN site regarding the error and I tried all the things which
they provided and I talked to my server people also to help in solving the
problem.

The error and description is as follows:


Server Error in '/' Application.
--------------------------------------------------------------------------------

Unspecified error
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Actually MSDN suggested to provide the full permission to the temp folder
and the impersonation of the data access in web.config file also. I did the
same things and the server people also saying that the temp directory is
given full permission.

Moreover I changed the database location and in connectionstring also I
changed the path. Even it didn't solved the problem. Please if anybody
solved such problems give your suggestions immediately.

Thanks and Regards,

hi,

check if you still have permissions to open the database file. maybe there
were some security updates?
