upgrading window 2003 to 2008r2 domain controller serious issue
in my company we have one primary domain controller running on window 2003 (32 bit) . recently we have bought HP new G 7 server and we wanted to shift domain controllers functions to new server . i made that server as backup domain controller then shifted all FSMO which is working fine . The problem is when i turn off my old 2003 server all the naming information on 2008r2 are lost and nothing appears in active directory users and domain. my DNS is configured correctly on both these servers.
please help me to sort this issue because it is creating lot of problems for me.
