The Tech stations usually are, but the devices themselves mostly not. GE Centricity workstations tend to be Windows 2000 Pro. Fujitsu/Siemens also tend to use Windows for the Tech workstations. Everything else tends to be some Unix variant.
Win 2k Pro can be patched to cover this...why wasn’t it? I’m usng a 2k Pro box right now and it was patched 3 days after the patch was released. Hey, gotta let the other fools find out which ones are totally broken, right?
