We are trying to use PRTG to monitor the last time windows update has ran. The sensor in PRTG that does that just pulls form the registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Windows Update\Auto Update\Results\Install\LastSuccessTime
This key isn't updating when windows update runs. We know updates were done in at least April 2013, but it continues to say the last time windows updates were installed was in Feb 2010. This is only happening to servers that are at remote locations, with a VPN to our main office. These boxes are all running Windows Server 2003 R2, this sensor is working on a machine with server 2003 R2 in the office.
We noticed in the same registry location that ...\Windows Update\Auto Update\Results\Detect and ...\Download are not updating their date/time either. We are using WSUS, but the servers in house are working with that sensor without problems, updating the date/time correctly.
We ran one update and rebooted one of the servers, as there was an error in a previous update so we figured that might have caused it, but it still wouldn't update the date/time.
I've posted in the PRTG community, but haven't had many replies, just one saying that they aren't having any issues, so I've come for the collective wisdom of Spiceworks. Any help, ideas, or suggestions would be greatly appreciated.
