Between Sunday afternoon and this morning, we started having permission problems on a file and remote desktop server. It is server 2008 R2, running as a VM under vSphere 5.0
The most pressing issue right now is not being able to access drive c:. There were also permission issues on drive shares from another drive, but if I can fix this one, we can probably fix the other issues.
The drive shows in the list, but clicking on it gives the above message. I have logged on under the local administrator account, a domain administrator account and my own user account, all with same effect.
output of icacls command from my account:
c:\: Access is denied.
Successfully processed 0 files; Failed processing 1 files
It is the same under the local administrator account and a domain administrator account.
Reading another issue on EE, I tried using the command to grant execute access to Users, but it failed.
