We are currently in the mixed environment. We are migrating from 2003 to 2012 domain controllers
Wherever I have installed the new 2012 my user are having issues logging in. it takes more that 10 minutes to login.
it only happens when the user is logging in for the first time on the computer.
I see event IDs 1053 &1129 on those computers.

Looks like GPO processing issue. Check all the Policy are replicating to 2012 server.

Have you removed 2003 server ? Check the replication and group policy errors in 2012 system events.

Post the event error logs

turns out it was an Anti virus issue.
We have bit defender and it was blocking communication.
I made exceptions for DNS server and now it is working correctly.
