You cannot offer Remote Assistance to another user when you use a mandatory profile in Windows Server 2008 R2

Applies to: Windows Server 2008 R2 Service Pack 1

Symptoms


When you log on by using a mandatory profile, you cannot offer Remote Assistance to another user. 

Note Offered Remote Assistance is also known as unsolicited Remote Assistance.

When you use the user interface or the command prompt (MSRA /offerRA computer_name), you receive the following error message. This message is possibly misleading. It states that Remote Assistance is not possible when a guest profile is used.

There was a problem starting Remote Assistance - Remote Assistance is unavailable for the current user account. If you are using a Windows Guest account, try logging in with another account. If you are not using a Guest account, try restarting your machine.

Cause


This problem occurs because Remote Assistance that is not unsolicited requires the cryptographic library to encrypt a Remote Assistance ticket. Cryptography is not enabled when mandatory or guest profiles are used because private key material cannot be persisted. However, for unsolicited Remote Assistance, cryptography is not actually required, and the error message is displayed incorrectly.
