Was just building a UAG test server in our lab and came across an error, which was easily resolved and worth posting for others.
From the splash screen I clicked install only to receive a “system.exception” error. Even if I ran the .msi file directly, I would get a failure.
A search returned one brief mention of a fix. I had a Group Policy applying to the machine that was disabling the Windows Firewall. As soon as I moved the machine account to a test OU where the policy would not apply and rebooted to refresh, the issue went away. Setup now runs without issue.
This is also mentioned in the troubleshooting section - http://technet.microsoft.com/en-us/library/ff607359.aspx
Further testing proved this may also occur if the Remote Settings for RDP are set to allow.
The most popular question I receive is how to best perform backup/restore of virtual machines running in Hyper-V without taking them offline. The best enterprise approach is Data Protection Manager and you may have already seen some of the extensions to this functionality in 2010. But what if you have just one server at a remote site and would like to run local backups from the host?
