I have both Win2008R2, Win2003 DCs, a 2003 Member server runing Exchange 2003 Server, WinXP & Win7 clients in my AD network which is based on Windows 2003 Forest. Now I want to decommission the W2k3 DC and Install a Win2008R2 DC in its place. When I browse My Network Places from W2k8r2 Server, I only see Windows 7 clients and not XPs and when I do same from W2k3 DC, I see only the XP clients and w2k3 servers and don't see the Win7 clients. Shares on either w2k8r2 or w2k3 servers can't be access from each other. Both my Roaming profiles and Redirected Group Policy folders are presently on the W2k3 DC and I've re-configured both to point to the Win2008R2 DC but this is not working. The XP and 2003 servers can't access any share on the Windows 2008r2 Server and Vice versa.
Could any please assist to solve this problem?
