It certainly looks like a network issue - do the users report any other problems with logging into their machines, etc?


BTW, you posted the username and password here for the sql server.

>I have a application that is client server based. When the app is launched, I create a connection to the SQL Server. At one client (there are 8 seperate ones using this application), they have a problem with some workstations (not all) that connect to the Database sometimes and then don't connect other times. These clients are all in different states than me, so I don't get to sit and try things on the workstation. But I have modified the application to capture and ftp the connection error data, the data is mostly from aerror():
