Friends, I am using MS Messenger in my Network with Exchange 2000 SP3 (in a Windows 2000 SP3) and I am found problems with the Messenger Server. My Messenger clients do not inform the logon or logout of other users (only with a new logon). So I deleted the RVP Server and create its again. After that, my Messenger clients can not logon (Messenger database problem???). Please, help me.
