We are attempting to upgrade from Windows Server 2000 to Server 2008. I tested everything with Server 2003 and it all worked fine, we should have gone with that version! Windows Server 2008 has many issues. First I had to manually modify the firewall to get ACT to work over the network. However now when the firewall is on ACT takes 30 to 60 seconds to load. If I turn off the firewall then it loads in less than 1 second!
