I have a bucketload of NT/Win2K/SQL (6.5/7/2K) servers I inherited. Short of going to each machine is there a command that will tell me the serial numbers of the NT, SQL installations on each machine?
xp_msver will give you some info, not sure if what you need though. Lots of information available via WMI, though it takes time to figure out, might be faster to walk around to them!
