Something is very, very wrong with their environment, then. I've seen Win7 come up faster on HD netbooks with worse system specs than what you posted downthread.
I've not seen Windows 7 perform well on anything with less than about 2GB of RAM. I certainly don't doubt that district configuration has compounded what are mostly hardware issues. The point was more about what type of hardware some organizations are still using. In this case the machine handled Windows XP combined with the district configuration, slowly, but tolerably and after the upgrade has lost a significant amount of its utility.
