When starting up and logging in to a Windows 2008 server, the login comes up quickly enough but once I enter username and password, it takes a long time before the desktop is available. First the welcome message shows for a couple of minutes, then "applying user settings" displays for minutes.
This server is only being used for SQL Server. It has no other applications, is not a domain controller, etc. The machine is a quad-core with 8G RAM, plenty of disk space.
By comparison, I use a W2003 server for the Primary Domain Controller. This machine is an old workstation, not much power, but it's much faster to get the desktop up and running.
