I have a group policy that has been working perfectly for the past few months, it's sets the Start layout, does folder redirection, disables a bunch of unnecessary things such as mail, store, etc, and does drive mapping. The policy applies to Windows 10 computers and about 70 users. It's been working perfectly, until very recently. I noticed it was no longer working when I logged in to a computer as a newly created user. The policy doesn't apply to that user. When I run the GP results on 2012 AD server, it doesn't even show up as one of the policies in the GP results. On a 2008 R2 AD server, the policy's GUID shows in GP result, but it's one of the denied policies, the reason for it being denied is "Inaccessible".
I have now tested it with several users and computers, and getting the same result as above (policy is not applying)
Any ideas? I am desperate.
