You may however want to upgrade your older server running 2k to 2k3 soonish though. When I upgraded the 2k-server to 2k3 I found it running smoother than before, even with the rather old hardware. One server is an amd athlon xp/1200 with 512M RAM and the newer (relatively speaking...) one is an intel P3/666 also with 512M rambus (expensive!) RAM. The intel was an athlon clasic/700 until the mobo died and I had to buy a server ASAP (in fact the same day it died...). These are for my home office. At work I have a lot more power available. 8-) 1. The one thing to look out though, is that there *may* be inconsequent GPO handling, especially if you upgrade-install a 2k-server to 2k3. This is a known bug with 2k-to-2k3 upgrades. Better do a fresh install if you can. The related technet kb-article is this one: <http://support.microsoft.com/kb/842933/en-us>. 2. Also, any GPOs you had from 2k will not upgrade properly to 2k3, which also *may* cause tricky problems and subsequent troubleshooting. For instance, you won't see any of the new available 2k3-GPO settings on your domain if your domain is still 2k-compatible, even on your 2k3-server(!). I raised the functionality level to 2k3-comaptible rather quickly because of this... Other than this, no probs. OTOH, these two problems above may be more than you bargained for... YMMV.
