I noticed that when I did a minor maintenance upgrade that afterwards my configuration was blank and it had lost all my targets. Not a great feeling since I spent time getting it exactly how I wanted. With a little poking around I discovered that the upgrade reset the service logon account back to "Local System Account" from the domain account I had configured. This would seem less than ideal.

Another thing I noticed but have not done further testing to confirm was that when I edited some of the DNS names after initial setup that a reboot of the server they reverted. It is not clear to me when/how setting changes are saved.

Thanks
