Applying computer settings takes long @ boot

Hi all,

I'm in strange situation after a migration from Windows 2003 Server with Exchange 2007 to Windows 2011 SBS. Everything seems fine, but server startup is slow, especially 'Applying Computer settings" takes long. It seems something to do with DNS or with IPv6 settings. IPv6 is enabled on the NIC because I know about similar issues with slow bootup when IPv6 is disabled. IPv6 has never been disabled. The server is running on VMware 5.1 vSphere.

At the end, after a long time, CTRL + ALT + DEL shows up, but some services (mostly Exchange services) did not start automatically. Manual startup works without a problem.

This is what my IPconfig looks like:
