Vault Can't Connect to Directory

I ran through a test migration/upgrade from 9.0.4 to 10.0.2 in my lab today.  Everything seemed to work OK, and all checks and steps passed.  However, now that I'm on my new 10 server, I can't open the admin console, and am getting this event repeatedly logged:

 

Event ID 8623

Cannot connect to the Enterprise Vault Directory service.

Check the Enterprise Vault event log on OLDSERVERNAME.domain.com to find the cause of the problem.

 

I am using an alias, so nothing should be pointing to this name.  My alias DNS entry has been updated, and is pointing to the new server.  Up until about 2 weeks ago, my lab was not using an alias, so I ran through this KB to change it: http://www.symantec.com/business/support/index?pag....

Any ideas before I open a support case?

Thanks!
