Need to remove DNS and AD from the Win2000 server

-Check all other servers' TCP/IP configuration to ensure they are not using the old 2000 server's DNS service.
-Check the DHCP scope for the network to  ensure the old 2000 is not listed in the DNS server option
-Check Exchange's settings to make sure it uses other DC's/GC's (http://www.msexchange.org/tutorials/Closer-Look-Directory-Service-Access-DSAccess-Part1.html)
-Check that the FSMO roles are transferred to the 2003 server http://support.microsoft.com/kb/197132 (note: running DCPromo to demote the old server will automatically move the roles from 2000 server to the remaining DC's, but I prefer to do it manually beforehand)
-Using DFS? Make sure the replica is removed from the old server.

After these checks, run Dcpromo on the old server to remove AD.

Have checked that the 5 FSMO roles are held by the Win2003 server. I did that using netdom.

Anything else to check? Global Catalog, netlogn share, sysvol share? How to check it?
