Hi,
We are having the same experience with prints over a Windows Server 2008 standard (x32).
It can take up to 30 secs before the 'printer preference' panel opens. It also slows down the opening of Word files when your default printer is one on Windows 2008.
All our printer connections are fast over an older Windows Server 2003.
I've chekced all the network settings, disabled firewall and unchecked TCP/IP v6 without results.
No solution found yet.
Any help is welcome!
Stefan
