I'm in a small location of a company and we only have 2 subnets here.  We're upgrading to SP2.  Some machines have been upgraded already and I'd like a way to poll the machines on the subnet to see which ones I have to do manually.  Would like to capture at least the sp level on the machines and ideally the node and username.  I'm thinking that there's probably some AD tool, but I have limited access to AD for our site.

Thanks.
