Also you should check your Syslog or whatever is in place (or get something in place) so you can see who is accessing your firewall, routers, switches and all that good stuff. This is just another Daily thing.
Documentation is the biggest thing, and man is it annoying. It's more pay, but I'd rather just go around fixing stuff for 10 hours per day instead of being chained to my desk and inputting the 75 new PCs that we bought and taking out the old ones in my database.
Anything you do needs step by step instructions, if you dont have documentation for changing the music on hold, or you dont have documentation for doing IDS signatures, or Antivirus updates, updates to the email antivirus, spam filter... Just junk like that will keep an Admin busy and keep them tearing their hair out.
Do you have all of the licensing in order, you can prove you have enough licenses for your servers and workstations for everything from Windows to Antivirus to Spam to Encrypting email... Anything you can think of, write it down and file it away.
