Remote Assistance Failed to initiate

Dear All,

On one computer, when I try to offer Remote Assistance to a user, intial screen is shown but error message "Logon Message - You do not have access to logon to this session" appears.
I'm a domain administrator and remote access policies are enbled.
I'm able to use Remote Desktop.

In the eventviewer I have nothing except information message "5270 - Remote Assistance : A remote assistance ticket has been created with duration: 0.17hrs for user <Computer name>\<username>".

Help !

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Not sure, but I would try with a different user profile/ login.

Perhaps a local profile is corrupted.

I hope this helps !

HI, Thanks for your proposition.
But I already try to use a different Expert / local user but I have this error message in all cases.
have you tried a repair install or at least

sfc /scannow

have you checked for viruses or malware ( Hijackthis ver 2.02 or newer at trendmicro- free )

I hope this helps !

Problem was due to wrong data in the registry here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server

Unfortunately I don't know exactly which key as I imported all the structure.
