If the statement is true that you learn from your mistakes and failures, then I am getting really smart today!
I have successfully started using templates in VMware for a short while now. I thought I was getting pretty good at it since I was standing machines up very quickly and with little effort.
Today, however, I discovered a “glitch” with my process. When applying policy that would have the servers check the local WSUS server for updates I found that none of the servers where showing up in the administration console. I checked my policy(I have been known to make mistakes before), but everything was just as it should be. I clicked the refresh button with fingers crossed. A server showed up! I must just be too impatient, so I moved on to something more productive. A bit later I checked again, still only one server. HHMM, I started thinking about this, and all of the servers should have checked in by now. I set this policy up days ago. Ok, now for some more investigation.
I logged on to a server and in the run command window, I typed the following:
That should be enough to set things straight, or so I thought. However, nothing changed, and after 30 minutes, I determined there was something wrong. I also discovered that the server that was showing up in the WSUS admin console was changing. I again used my friends on the internet to get some answers. There were a lot of different suggestions and recommendations, but none of them really fit with my situation. Then I stumbled across this website: http://rialtus.livejournal.com/161268.html. This was the answer I was looking for. I exported the registry key that I would be removing, picked a server that didn’t have a good deal of importance at this time, and deleted the following registry key:
I rebooted the server and entered the following command in the run window
wuauclt.exe /resetauthorization /detectnow
The server appeared in the WSUS administration console. Success! I repeated this process for all the other servers I created from the template and the results were the same. I had fixed the WSUS issue of my server not showing up in the console.
