UAG and Windows Update

It is not uncommon to run into problems when trying to use Windows Update on the UAG server. This is mostly due to the fact that UAG server runs on a harden configuration, protected by TMG.

In most cases running the following command from the elevated command prompt will resolve the issue:
netsh winhttp set proxy localhost:8080
It is always a good idea to check on the configuration before changing it, so you may want to try run this first and make a note of the output:
netsh winhttp show proxy
The following link contains some additional information - on the aforementioned, and this one has very detailed information on troubleshooting Windows Update on TMG -
