MSDE permissions conflict in C# app

Hello All experts,

I have developed an application in C# which uses an MSDE database as its basis. I have developed an installation routine which installs the .net framework, MSDE database and finally the application. When I install the standalone application onto a machine with Win 2k, Win XP Home or Win XP Pro as the OS and then run the application, it runs fine.

However when I install the application on a WinME or Win98 machine and run the application I get the following error:

"Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection"

I checked my connection string which was initially as follows:

"data source=local host;integrated security=SSPI;database=Jaguar;persist security info=false;packet size=4096"

Then I entered the "Trusted Connection=yes"

The connection string then evolved to:

"data source=local host;Trusted Connection=yes;integrated security=SSPI;database=Jaguar;persist security info=false;packet size=4096"

but it still pops up with the same error message.

Why does it work on Win2k, WinXP and not on WinME? Do I have to manipulate a registry setting, do I need to set some extra parameters for MSDE during installation?

Can you experts please shed light on this situation?

regards Imran

Is the data source really equal to "local host"?  Try localhost or even better try the machine name

This connect string works for me:
SqlClient.SqlConnection conn =       new SqlConnection(@"server=mcName\SQLBASE;database=Northwind;Integrated Security=SSPI");

Hi Experts,

I was missing the "User ID = sa" in the connection string.

Thanks for the pointers

Now, can you tell me how that connection string is any different than the one you start with?
