I added new server in the network and everything worked fine. Old server is Windows 2003 SBS and new server is WIndows 2008 standard exchange (same domain). I mooved exchange from old server to new server and everyting was still OK (replication, acces, workstations). After some 5-6 days some of the workstaiton lost the connection to the old server (connection to the new server was OK). Afer restart of the workstations everything was again OK until next day. All WS are loosing connection to the old server from time to time and after restart is everything OK. I can not access the old server from the new one any more \\oldserver (nothing changed in password, updates or so). I get an error "Logon Failure: The target account name is incorrect". I would like to exchange rolles and remote old SBS from the net but in the menu for RID, PDC and Infrastructure I have always errors so I can not do it.
Thanks for help.
