What causes a terminal session auto-completion of a Windows Server 2008 R2 user?

Question

System administration

Good day. Faced another deadlock situation.
Available:

• terminal farm on Windows Server 2008 R2 with automatic balancing
  
• non-roaming user profiles
  
• harmful user
  
• quotas
  

The essence of the problem:
This user is thrown out of the session for the second time with the closing of all the programs he has started. A person picks up a solution in a serious program and suddenly throws it out for no apparent reason. Throws out 2 times a month.
What I watched:

• quotas . Checked and cleaned the user's garbage. Yes, quotas have been exceeded. But I did not find any enabled parameters that allow you to end the session (and in general, are there any?)
  
• group policies . Watched everything. Those parameters that introduce any restrictions or even somehow indirectly relate to this situation are simply "not set"
  
• remote desktop services . There are no restrictions on session duration, idle time, etc.
  
• this user's RDP connection settings . The settings are typical, the same as everyone else
  

I can’t say anything about other users, because there were no complaints from other users. Help solve the problem, please!

Answer 1

Try deleting the profile. After creating a new one, copy everything you need from the old one.
Whether it will help in your case, I don’t know, but other strange problems that appear only for one user managed to win in this way.

Answer 2

Maybe it's a network connection issue? It happened on some users - after putting in order the problem disappears. Just if other users do not have such a problem, then the settings are in order.
