We have a 2008 data center server that takes 2-3 hours to reboot. I am pulling my hair out try to find out why (and I don't have much to pull out). It didn't do this when it was new, but picked up this bad habit awhile back. It will boot up fine, and get to the Windows screen with the horizontal progress bar. After that, it goes to a black screen with a white cursor (which I can move). If I let it sit at that screen for 2-2/12 hours, it will boot and be ready to go. Here are some facts about the server....some may be irrelevant, but I'd rather include everything
It is an HP D360 G5 with Windows 2008 Data Center
It has 2 ethernet ports. One for the host, one for the virtuals. Removing it from the network during boot does not help.
It does this whether it has updates to install, or not
The server is a Hyper V host for 4 virtual servers. It does this even if I shut down all of the virtuals before I reboot.
We do not have snapshots running
We have 1 other physical server that does DHCP and DNS for the problem server. The problem server has a static IP
The server has 3 roles (File Services, Hyper-V, Web Services (IIS). It basically does nothing but host the virtuals
It has 4 features installed (.NET, Remote Server Admin Tools, Telnet Client, Windows Power Shell)
It has 4 300GB SAS drives. They show up as 2 partitions. RAID 5?
That is all I can think of to tell you. Please help!
