Is there a way to deny logging on to the domain with a user who is already logged on? I want to be sure that every moment no more than one person is logged on (on any machine in the domain) with any domain user account. Every suggestion will be helpful for me. Thanks

you may try cconnect.exe from Windows 2000 Resource Kithttp://www.windowsnetworking.com/kbase/WindowsTips/WindowsNT/AdminTips/Logon/RestrictingConcurrentLogons.htmlhttp://www.sysadmins.lv

no, this is not possible. you would have to be monitoring the logins from eventlog and may be react appropriatelly only post-logon.odnrej.
