GPResult error The user does not have RSoP data fails as Domain Admin
Solution 1:
Yes, it can be done without doing a interactive login, although you need to know a user that has actually done an interactive login on that computer. In your case, UserA would do it. Then, from an elevated prompt:
gpresult /user UserA /scope computer /r
Also, from a remote computer:
gpresult /s RemoteComputer /user UserA /scope computer /r
I really don't get why you need to specify a user when using /scope computer, but this is how it works...
