ArcGIS Desktop 10.1 License manager concurrent use invalid hostname

I've upgraded to ArcGIS Desktop 10.1. Uninstalled both old versions of the license manager and desktop then installed version 10.1.

I'm running license manger on another server with a concurrent use license. All diagnostics on the license manager check out good but when I try to define the license manager for a desktop installation it responds with an invalid hostname error. I can ping the hostname and it resolves. I've even temporarily disabled Windows server 2003 firewall.

Any ideas?
