So a few posts ago I described how to setup the “Offer Remote Assistance” feature for a domain. It’s been working just fine, until yesterday. When trying to connect to a specific computer in our network a “Message: You do not have access to logon to this session” message would pop up. It was usually followed by an EventID: 5270 in the event logs.
After much searching and trying various stabs at the solution, one was finally found. For some reason, still unknown to me, one single registry entry was different that broke Remote Assistance on the computer. On the computer that isn’t working, check out HKLM\SYSTEM\CurrentControl Set\Control\Terminal Server\fInHelpMode On the broke computer, it was set to 1, where working computers was set to 0.
I first tried just setting the entry to 0, but it still didn’t work, so I removed the key and restarted the machine. Working.
If your seeing this issue, hopefully this post will solve it quick.
