Hi
When I try to use a user other then SA my console apps don't work.
I can run the Stored Procedures used in console application from Query analyser when logged in with the username/password that
I'm attempting to use for the console applications.
Under Users in Enterprise Manager Database access is 'permit' for my user.
By the way my web application which uses the same user name and password as in console applications is working. I also have dts packages running using dtsexec accessing the database with the same user name and password and they work fine.

C:\Program Files\Microsoft SQL Server\80\Tools\Binn>ODBCPING.EXE -S xxx.xxx.xxx.xxx
-U myusername -P mypassword
CONNECTED TO SQL SERVER

If the connection is available then why is the adapter.fill method failing?
I tried it using a text sql statement and that doesn't work either.
The problem isn't database specific as I did a test .bat on Northwind sample database and got same 'general network error'
Here's the error:

Any ideas/help much appreciated!
Hi,
would be cool if you could show us your code.Sometimes people hardcode certain properties (I confess that I did that on my own one time :-) ) which will lead to an error where usally there shouldn′t be an error (especially in console apps where connection properties are passed via arguments which isn′t testable while debugging within VS)

Hi,
Here's the essentials of the code (without some try catch statements).
Thanks.

|||Hi,
beside that the FaultReportDapater doesn′t exists (but I guess this is just a typo) you can try disabling the connection pool to see if it is based on this with adding the keywords "Pooling=False" to the connecting string.

Hi,
Yes that was just a typo. With pooling set to false I still get the same error.
Thanks

What is the call stack of the exception if you disable pooling?

Here's the call stack with pooling set to false.
