CA Synchronization Issues with AD

In July we upgraded our EV\CA environment to 10.4. Since that time, we have not been able to get our employee accounts to synchronize with AD. The last time they did was a few hours before the upgrade. Employee groups that point to an AD group synch fine, but employees do not. At the request of support I reinstalled CA, however the issue remains. When the AD Synchronizer runs, I get the dollowing;

Curious if anyone has anything else I can try
