Since updating to the latest beta, I've been seeing this error in my C:\Program Files\Lansweeper\Service\Errorlog.txt file. I have about 8 pc's with this error.

As it turns out, all the PC's showing up are Gateways. I looked on my 3.5 version that I still have running and yes, they do show up in that log file too. We just added those users to our domain a few weeks ago, so I guess they jumped out at me when I looked at the 4.0 log file.
