0x80070522 A required privilege is not held by the client. when Join TMG server to Array

Dear Team,

I have an issue with TMG server, it is happening when I tried to join server to another one for Array setup, I tried the following scenario and all failed:

1. Join TMG1 to TMG2
2. Join TMG2 to TMG1
3. Join TMG1 and TMG2 to separate EMS server
4. Make a fresh installation of Windows and TMG

The below error code is appearing with all scenarios

Operation Failed.

0x80070522

A required privilege is not held by the client.

Also I have the following in TMG logs

No answer file was given for the Array Membership Type page

No answer file was given for the Array Manager Details page

And this error when I tried with EMS

No answer file was given for the Array Membership Type page

No answer file was given for the Enterprise Management Server Details page

No answer file was given for the Join Array page

I have TMG 2010 with SP2 for all servers, all servers is member of managed array server, it is a fresh installation, No error message in event viewer and the user used for the installation is domain admin membership.

looking to hear from you any hints or guide to solve this issue 

Thanks
