SBS / TS monitoring

Hello! I've asked this already but I've not received an answer. I hope someone can help a bit.

We have a technician in our company and he has written in his "Monthly Tabs" that he checks/controls SBS and TS server every second day for roughly two hours. I don't know much about this except that it should be 2003 version or something?

Should he be doing this so often or is he just taking the money for nothing?
Thanks a lot!

Here's a list of what he says he does: (I tried to translate the best I could)
