Remote Control fails with error C000012 in System Center 2012 Configuration Manager


Symptoms


When attempting to using System Center 2012 Configuration Manager to Remote Control a system, the connection fails.  The Remote Control log and CmRcService.log indicate the following failure:

  WT_CompleteIO failed. Network shutdown : Unknown error (Error: C0000120; Source: Unknown)

Cause


Certain User Configurations for Remote Desktop Gateway block the remote control session from successfully connecting.  The User Configuration settings are:

        Enable connection through RD Gateway: Enabled

o   Allow users to change this setting: Enabled

        Set RD Gateway authentication method: Enabled

o   Allow users to change this setting: Enabled

o   Set RD Gateway authentication method: Use locally logged-on credentials

        Set RD Gateway server address: Enabled

o   Allow users to change this setting: Enabled

o   Set RD Gateway server address: (enter generic FQDN)

 

Resolution


To resolve this issue, either do not configure User Configuration settings for Remote Desktop Gateway (leaving them as “not configured” as opposed to “enabled”) or specify the RDS Gateway settings as part of the Remote Desktop Connection client user interface  in the .rdp file.
