Looking to help to finalize upgrade process for Active Directory to Windows 2008 R2

Dear All,

I’m in a pilot phase to upgrade my Active Directory from Windows 2003 to Windows 2008 R2. I installed the new windows 2008 R2 domain controllers and thy are ready now. FSMO roles have been moved to the new servers, all DHCP scopes pointing to the new servers.

I need to do a test to make sure everything is working fine with the new domain controller, I want to shut down the old windows 2003 domain controllers but I’m facing issue here,  the DHCP service still running in the old domain controller, so I can’t shut down them!

I’m looking for a way which I can stop all services related to the active directory in those servers, but I can’t list what exactly I have to stop!

Please help.
Thanks

ADDS can not be stopped in W2K3. It can in W2K8 and up.

You can't in Windows 2003 (no stoppable AD Service).  How long are your DHCP leases?  

Do  you have DNS on the new server?  If you do have you updated the clients (DHCP and static) to use the new box for DNS?

Thanks

If application and clients point to the new DC(s) and have you not faced any issues as yet, what makes you think there might be a problem ? Are clients still authenticating against all W2K3 DC ?

Have you (from AD Sites and Service) ensured that subnet has been associated to the new-dc site, if you in fact did create a new site for the new dc(s) ?

If DHCP has been configured on the new servers, there won't be any problem.  

If not, go ahead and configure DHCP on the new server(s) and copy the database over:
