Secondary computer delegation error: access denied.

To resolve the issue that you are getting, you will need to use the following simple procedure:

• First,  you will need to go to the domain controllers group policy.
• After that you will need to open the Group Policy Tab and then do the following:
• You will expand “Default Domain Controllers Policy, and then click Computer Configuration.
• After that click on Windows Settings, and then Local Policies.
• And then you will click on User Rights Assignment” and locate the “Enable computer and user accounts to be trusted for delegation”.
• You will then open this Policy and then add the group or user who should have rights to add delegations:
• After that, you can try again. This time round you should have no problems adding delegation to the user.
