Can't see all computers in network places

After adding a new 2012 DC to our existing 2003 DC we ran into some issues.  The fsmo roles have been transferred but when any computer browses the network most of the computers don't show up.  Why is this happening?  I can map to each computer if needed but the names are not coming up in the network page

Check in the Group Policy if a rule for Turn Off Network Discovery is in place

All computers cannot see or just some?

Check out Advanced Network Sharing settings (particularly turn on Network Discovery as suggested above). Make sure the network card is attached to Domain and not Public or Private.

Your help has saved me hundreds of hours of internet surfing.

Take one computer that cannot, and try the suggestions above. Be sure to restart after any changes and allow to re-browse.

I did that and Network Discovery is on.  It worked fine on the previous Domain Controller.  When we added the new controller, then the problems began.

Is the problem computer seeing the original DC?  Is there a conflict between Domain Controllers?  Perhaps the roles did not all transfer correctly.  There is otherwise no issue for me to browse Server 2012 and its computers.

Yes, some computers can't see the new DC.  Is it possible that there are some entries that I need to look at in my DNS server?

The DNS (and DHCP) should only be handled by one server (in my experience). Server 2003 is dead, so presumably you want to decommission this.

The DHCP is handled by our firewall hardware.  Should I move it to the 2012 server?

Also, since I have DNS running on both the 2003 and 2012, what do I need to do to bring down the 2003?
