Installed on one machine (a clean install rather than upgrade) with no problems. Had to turn off the Microsoft wireless software so that my normal Netgear WiFi control panel would work correctly - other than that all is OK.
Second machine to be installed next week.
It does require a bit of work to get the security options configured to your liking, but it seems once done it works just fine. Initial problems with SP2 were incompatabilities with other programs - I belive most of these have now been fixed.
