Cannot change registry keys permission

Posted on 2004-08-14

This started while trying to update a driver for an internal Intel NIC

System identifies H/W as Intel Pro Ethernet Adapter and finds driver. After installing driver returns an error access denied.

Checking SETUPAPI oog it show access denied while updating key HKLM\SYSTEM\CURRENTCONTROLSET\SERVICES\E100B
Using REGEDIT and selecting the key an error is returned "Error Opening Key Cannot open E100B: Error While Opening Key.

Attempt to change permissions and an error "You do not have premission to view the current permission setting for E100B, but you can make permission changes"

Click OK and the "Permissions for E100B" comes up

There are no users or groups listed.

Add Administartors default shows allow special permissions checked, Select Full Control and apply. Error "Unable to save permissions changes on E100B. Access Denied"

I used AccessENUM to get a list of permissions for the registry. Several entries had ??? listed in Read Write and Deny

Also the key HKLM\SECURITY\Policy\Secrets\SAC and SAI both show the ???

Any ideas on correcting this or do I have to do a reload? System restore was turned off and there is not a backup of the registry.

Have you tried taking ownership of the key in question, and afterwards changing the permissions? Click the Advanced button in the security settings, go to the "Owner" tab, highlight the "Administrators" group; check the "Change ownership of objects ..." at the bottom; click OK. Close the Security window, re-open it, and you should be able to re-add the Administrators group (and perhaps other permissions according to other Services keys) to the permissions (if necessary at all).

Thanks oBdA!

You hit the nail right on the head.

Still trying to find out how these keys were changed. This is not my PC so I don't have a complete history
