sql server connect: I'm using VS2005 pro to develop one windows form and one Mobile5.0 app ,
they are simple apps and just connect to SQL server to get data. The SQL
servers include Win2K + SQL2K, Win2K3 + SQL2K5 std and Win2K3 + SQL2K5
Express.

All works fine until one day I updated Win2K3 patches to the sql server via
windows update.
The mobile 5.0 app can not connect the SQL 2005 express any more, it will
get error message:
"Can not find specific sql server SERVERNAME\SQLEXPRESS", I didn't change
any codes
or settings. But it still can connect to SQL2000 or SQL 2005 std.

The Windows app is able to connect to SQL2000/SQL2005 std/SQL 2005 express
without
any problem.

Any clue? thanks in advance!

Apparently, that's not a supported configuration. I'd seen that some
people had tried it and gotten it to work, so maybe MS did something
active to turn it off.

I don't know why it wouldn't be supported. I assume you are using SQLClient
to connect to SQL Express? Do you get an error message on the client? Are
there any errors in the SQL Express error log?

Yes, I used the System.Data.SQLClient in the Mobile 5.0 app.
The problem here is it works for SQL 2005 Express in the begining.
But it's failed after applying windows 2003 patches.
