Removing a Windows 2003 schema from a Windows 2000 domain

Hi,

I have a friend who is having problems. He wanted to exchange 2003 onto his network. So he did a 2003 domain prep (even though he wasn't going to be running Windows 2003 DC's!!) on his network. He then installed a Windows 2003 member server, and did a exchange 2003 schema prep.

Now his network is having lots of problems! He is running a Windows 2000 PDC, and a Windows NT BDC. He cannot log on as Domain Admin, the only account that works is the account that he used to do a schema update. His NT4 workstations can log on now and again.

My first thought is that because he has put the Windows 2003 schema on the 2000 network without installing 2003 DC's this has messed things up. Am i correct in thinking this? Is there anyway to restore the schema otherwise than doing a authorative restore on the 2000 DC?

Your friend has ignored all the readme files on the installation CDs!

It is impossible to remove the ADPREP schema changes from Windows 2000 AD as Schema changes on Windows 2000 are permanent without a pre-upgrade backup and an authoritative schema restore.

This is not the reason for his troubles. I suspect his troubles are largely to do with DNS. Your friend should start looking at his DNS installation to see if it correct.

Thought so. Am i right in thinking that a 2003 schema in a 2000 network without any 2003 DC's would cause these problems?

No, the 2003 AD schema updates don't cause problems and you need never install a 2003 DC
