Hi, I'm facing problem that - We have Exchange 5.5 SP4 under NT 4.0 - Most of the users have 2000 professional. They are working well - The problem is with the Windows 9x users. When they press ESCAPE at logon screen and try to check their mail through Outlook they fail. Question: Is there any way to prevent those users from pressing ESCAPE and force them to logon to the Domain Thanks a lot
