I am currently migrating my network from an NT environment to a Windows 2000 environment with Advanced server. Currently, I only have one Advanced server with a brand new forest and it is the only DC with Active directory installed. I have just installed the Exchange Schema updates and get this error when I run DCDIAG
Testing server: AlisoViejo\AVDC01
Skipping all tests, because server AVDC01 is
not responding to directory service requests

Can anyone help?
