You also might want to run 'gpupdate /force' to verify that the GP settings are not effecting it.

I wanted to add some notes. While Tim's answer didn't work it helped put me on track to the right solution. I am documenting below for the record.

Change the DCOM permission by the steps below.

1. At a command prompt, type the following command to open the Distributed COM Configuration Properties:
"dcomcnfg.exe" (without the quotation marks)

2. Expand Component Services/Computers

3. Right click on My Computer and select Properties.

4. From Properties, select the Default COM Security tab.

5. Under Access Permissions click on "Edit Default"

6. Add the Administrators account or your account, set "Access Permission" to "Allow".

7. Apply the changes and reboot the machine.
