In Active Directory Sites and Services, both Server1 and Server 2 are listed
as IP Bridgeheads, and both are GC's. Both servers have Active Directory
integrated DNS running on them.

Hello Haji,

For WINS, any WINS server must ONLY point to itself. So for each DC, if it is a WINS server, it must only point to itself, not it's partner. This is one of the rules for WINS servers due to it's own self registration and owner of records, otherwise it will cause problems with WINS. Not saying this is causing any problems with Sysvol or the dcdiag errors, but will affect WINS services. Clients can point to both.

What Event log errors exist on any of the DCs?

Is there any firewalls installed on the 2008 DCs Windows 2008 has the local firewall running by default. I would suggest to disable it. There are three parts of the firewall on 2008. To get to the settings:
Open Server Manager (right-click My Computer, choose Manage)
Expand Configuration
Right-click "Windows Firewall with Advanced Settings"
Choose Properties
Click on the Domain tab, Firewall State, choose "Off" in the drop-down box.
Click on the Private tab, Firewall State, choose "Off" in the drop-down box.
Click on the Public tab, Firewall State, choose "Off" in the drop-down box.
