I'm trying to utilize SUS on my W2k Server with a W2k/XP network. I think that I may need to install SUS SP1, but I'm not sure. The SUS admin page on my server says that it is Version 1.0.3630.2552, but the SP 1 web page says that it is Version 5.4.3630.2552. Am I that far out of date, or am I misunderstanding something. I just downloaded and installed this a few weeks ago. I've found an entry on the server for SUS, but nothing for SUS SP1 in the add/remove programs window.
