Tonight I applied the patch to the two servers that run the blog site and one (Yoda) got stuck on shut down. Fortunately the other (Brianna) didn’t so I was able to go to her and run a shutdown command of
shutdown -r -m \\Yoda
Mind you Philip recommended that I do a shutdown -r -f -m \\Yoda as that will force the reboot. Now in a real production/we need this up all the time/server you would be wise to install a remote IP device that would allow you to get access to the server below the operating system. Many of the quality servers have this with special network cards (iLos for HP, DRAC for Dell).
If you start moving more things in a hosted setting, having remote management below the OS level is key.
