Windows 2008 R2, and possibly some other later versions of Windows, have a problem with being remotely monitored by non-domain accounts. This blog post will show how to work-around this Windows “feature” that disables such monitoring.
Recent versions of Windows introduced UAC– User Account Control. While this may be useful on some workstations, most server admins will disable it so they don’t spend half their day clicking ‘yes’ on prompts. What many don’t realize, however, is that disabling UAC on the server doesn’t disable “remote UAC”– most people don’t even know such a thing exists…
Well, it does– and it causes remote monitoring tools like Overseer to **not work** when utilizing local accounts. Domain accounts will still work to monitor the computer, but if you’re trying to monitor a W2K8R2 computer that is not a member of a domain(and therefore using local accounts), you may run into this issue. This is further obscured by the fact that this remote UAC does not appear to affect the built-in ‘Administrator’ account– only separate users that should normally be allowed(members of Administrators group).
Well, the solution is here. To disable this ‘Remote UAC’ feature, you can add this DWORD registry value, setting it to 1:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\LocalAccountTokenFilterPolicy = 1
No restart of the server or any services is required. Note that this registry change must be done on any servers being monitored by Overseer– not just the computer running Overseer itself.
For convenience, you can use the .reg file below to add this registry key, or you can do it manually using regedit.
