I tried SP3 today. Loaded from a windows disk I had slipstreamed. Just two problems, had to load IE7 from Windows Update cause the version I had downloaded before wont install, IE7 kept doing the Run Once thing every time you opened it, had to stop that with a regedit. IE7 still now working right, wont open new tabs or link and wont work with gmail. IE7 and SP3 seems to have lots of issues. Going to install to SP2 again tomorrow morn.
Other thing was network related, had to turn the authentication stuff under the network card "authentication" tab off because though it got the IP from the DHCP it didn't want to allow my Novell login to run.
