It's always interesting to read about other workplaces and the people working the jobs, but why does the media always hype things so much.
I agree with the other poster - a real one man show would do it all, and that's becoming impossible, especially in a large university or government workplace.
When I first started at this small, computing intensive federal research lab 10 years ago, I did everything. Now I've had to off-load e-mail entirely. Web and ftp serving I now have just staging servers. Windows domain admin is shared with a parent lab. Security functions are partially controlled by the parent lab. As the only on-site IT, I still do local network admin, desktop and workstation helpdesk (still get all those windows questions here), admin the dozen servers, and do all the purchasing - and those "special" projects that come up.
But I'll freely admit that in today's workplace, with new regulations and mandates coming down weekly it seems, I still can't keep up. Of course, if you have a huge budget (mine is tiny), and don't worry about security (didn't see that mentioned - and I have to apply patches promptly and turn in scans showing compliance)...
I'm sure this is completely disjointed - keep getting interrupted with Monday morning stuff.
