I have a stored procedure ln a sql 2k database.  I call the s/p from a vb.net application it works well about half of hte time .... the other half it fails with the following error...
Timout Expired. The timout period elapsed prior to completion of the operation or the server is not responding.

I have been playing with the connection timeouts, but it does not seem to change anything.. as I am a newbie it could be that I am not using them correctly ... thanks for the help
