Group policy containing various security options not applying to some Win 7 machines but others it works fine. One example is "Interactive logon: Do not display last user name" under computer configuration>policies>windows settings>security settings>local policies>security options
When running RSOP the settings show as not defined, I've moved one of the computer into a separate OU and created a test policy with just a few options but it still fails to update the client
I've enabled gpsvc logging but nothing seems to be listed as a problem, I've checked the client can access the policy from the DC and run netdiag
Any ideas?
