I have a server Windows 2000 controller of domain that controls the users to occupy applications that it in another server and it has installed exchange 2000 server and instantaneous messenger. This server lose his name and the name of the domain nevertheless authenticate the domain users and gives the services of mail and messenger, but does not see the users of the network and it self. Apparently all the services are working well like for example IIS, DNS etc. NSLOOKUP does not find the name of the server and says that domain for the IP of the server does not exist. As I can recover the condition of server of the dominion?
