Very Slow (Everything) Server 2008 Ent 64-bit

Well, if you're sure it's not bogged down (and it appears not), what does process monitor show you the system is doing while you're waiting? Anything?

Just a thought as you think it network related

There have been lots of issues with Windows 7 regarding network performance when TCP AutoTuning is enabled which I experienced at work.

You can check your settings by running this command

netsh interface tcp show global

Also if you just want to test by disabling it run this

netsh interface tcp set global autotuning=disabled

to set it back run this

netsh interface tcp set global autotuning=normal

Worth a try but you should reboot the server after making the change..
