Domain Controller Trouble when running DCDiag.exe on Windows 2003 Server
Posted on 2004-10-19
I am currently Migrating from Exchange Server 5.5 running on an NT Server to Exchange 2003 running on a Windows 2003 Server(computer name: exchange-2003). One of the steps in this process is to run the DCDiag Tool on exchange-2003. When I run DCDiag.exe I get the following error:
***Error: exchange-2003 is not a DC. Must specify /s:<Domain Controller> or /n:<Naming Contex> or nothing to use local machine
I already have a Domain controller running on an NT machine called MyDC. So I ran the following:
I got the following error:
[MyDC] LDAP search falied with error 58. The specified server can not perform the requested operation.
***Error: The machine, MyDC could not be contacted because of a bad net response. Check to make sure that this machine is a domain contoller.
Now I'm guessing I got this error because MyDC does not use Active Directory which runs on the LDAP port.
So now what should I do?
1. Do I promote exchange-2003 to Domain controller for the purposes of running DCDiag and then demote it? What are the consequences of doing this?
2. If I do promote exchange-2003, should I do this through the NT machine or through the Active Directory Wizard on the Windows 2003 Server?
3. How do I demote exchange-2003? dcpromo? How is dcpromo used?
4. Once demoted, will exchange-2003 continue to run Active Directory so that I may continue with the Migration from Exchange Server 5.5? How do I check this?
Please include as much detail as possible with your answers..this question is worth 500 points..Thanks
