manually assign KMS host to client running Windows Vista or 7
Windows Vista and 7 under MCCA at UCLA are validated through a KMS server on campus. If for some reason Windows Vista or 7 doesn’t automatically validate through KMS you can manually assign the KMS host to your client.
Go to the command prompt and enter
cscript \windows\system32\slmgr.vbs /skms 128.97.141.165
There are two KMS servers and either one can be used.
a. kms1.softwarecentral.ucla.edu 128.97.141.165
b. kms2.softwarecentral.ucla.edu 128.97.141.90
After a short pause you will be notified of the success of the connection within the command prompt.
