You Receive a Remote Assistance Error Message Stating That the User Has Closed Connection to Your Computer

After you receive an invitation from a user that is asking for Remote Assistance over email, you open the invitation, and then you attempt to make the connection, you may receive the following error message:
On the client computer to which you are trying to connect, there is no indication that the user was trying to connect by using the Remote Assistance invitation.

This behavior can occur if a user removes the Authenticated Users and Interactive groups from the Users local group. To successfully run the Remote Assistance service account must have the privileges of the Users local group. By removing both Authenticated Users and Interactive groups from the Users local group, the removal of these privileges from the Remote Assistance service account also occurs.

Part 1

To resolve this behavior, determine if the behavior that is mentioned in the "Cause" section of this article is the actual cause of the error. To do so, determine which groups are members of the local Users group by running the following command from a command prompt: If no one has made any changes to this group, you should see the following members listed:

• NT AUTHORITY\Authenticated Users
• NT AUTHORITY\INTERACTIVE

Part 2

If neither group is listed, add one of the following groups to the local Users group by running the corresponding command:

• To add the Authenticated Users group, run the following command:
  net localgroup users "nt authority\authenticated users" /add
• To add the Interactive group, run the following command:
  net localgroup users "nt authority\interactive" /add
• To add the HelpAssistant local account group, run the following command:
  net localgroup users HelpAssistant /add

This behavior is by design.
