In this post we will see how to fix ConfigMgr CMG Error – The remote name could not be resolved. If you have setup SCCM CMG for the first time and noticing the same error, this post is for you.

I recently upgraded my lab running SCCM 2002 to SCCM 2006 and decided to setup ConfigMgr CMG from scratch. I had done it once in the past so I assumed it would go all well.

And for CMG troubleshooting, you can use refer my post on CMG log files.

Running the SCCM CMG connection analyzer showed the following errors.

  • Check configuration settings of the CMG service – Error
  • Check connection status of CMG connection points – Warning
  • Testing the CMG Channel for management point – Error
  • Check CMG enabled site system roles – OK

Checking the SMSAdminUI.log shows the error :-
