What were the logon times before Trend was installed? As your on 2003 switch on UserEnvDebug and check what is getting loaded. I'd be surprised if it was just Officescan causing the problem, it's most likely just highlighting an underlying issue.

Some users it will take up to 15 minutes to log on. Is there an exlusion list needed. Or anything else I should be aware. Thanks in advance
