Article ID: KB5465 KB Last Updated: 22 Jul 2010Version: 4.0
Why Can't I Login to a Windows 2000 Server?
  • Kerberos is used for authentication when active directory is configured.
  • Windows 2000 server
  • Windows 2000 domain

note: Make sure that the DNS server used by the client will respond to the DNS queries.

Example: The IP address of the domain controller is and the nslookup output would be:

C:\WINNT>nslookup [Enter]
Default Server:
> server [Enter]
Default Server:  []

> set type=srv [Enter]
> [Enter]
Server:  []
Address:  SRV service location:
          priority       = 0
          weight         = 100
          port           = 389
          svr hostname   = internet address =
note: If the nslookup does not return the proper DNS records, the problem is most likely on the Windows 2000 Advanced Server configuration.

Active Directory depends on DNS to resolve the name and to locate the domain controller. A new type of record is then created on the DNS, called a Resource Record.
