I am having problems installing Recorder on our network. It installs without any problems, but on trying to run it I get 'SQL Server does not exist or Access Denied' - However, I have 8 workstations on which it installed and is working perfectly (!), only on any subsequent attempt is it failing - I know SQL Server Express has a limited number of users, but I thought this was concurrent, not total!

Setup
Windows server running SQL Server 2005 Express
Workstations either Windows 2000 or XP - no pattern to failures

Help!
