IT is poorly capable of handling computers and software at the three institutes I've worked at (2x university, 1x government). We had our own private sysadmin at one of the faculties that did allow us to be productive researchers, rather than crippled ones. Scaled-up-to-whole-organization IT don't work that well in my experience, and getting anything sensible done (such as upgrading from IE6, or scaling 10mb mailboxes up to something fitting to this millenium) takes 5 years.
Now we've both vented about 'the other guy', can we get back to normal and not assume we know the quality of the IT the OP is working with, the real job description of the OP, and his psychological profile? The guy is asking a question, and a sysadmin could tell him why his IT service finds it sufficient to have an account on the server to allow it.
