VBScript runtime error: Permission denied: 'GetObject'

This script remotely retrieves the status of the "Patch Link" service from Windows XP workstations. When it works the workstation's Ip address and service status is written to a file.  Here is a success result.
192.168.10.20 - Patch Link Installed AND is Running
When it fails it is failing because it does not have permissions to access the workstation.  Here is the error.
C:\Scripts\Ck4PatchLink.vbs(24, 3) Microsoft VBScript runtime error:  Permission denied: 'GetObject'
Here is line 24 from the code.
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer &
      "\root\cimv2")

Here are the things I have done.
1.  Verified the script is logging on to the remote workstation using the administrator account.
2.  Verified administrator passwords.

3.  Verified WMI security by => Right-Click 'My Computer' >> Manage >> Expand 'Services and Applications' >> Right-click 'WMI Control' >> Properties >> 'Security' tab >> Expand 'Root' >> Select CIMV2 and click security and verify that the account you are using has the appropriate perms and also check you have appropriate perms on the WMI location as well (normally "C:\WINDOWS\System32\WBEM"

4.  Verified there are no firewalls between the two computers.

5.  Confirmed that the script runs locally on the remote workstation.

6.  There are no DCOM errors on the remote or local workstations.

7.  Check DCOM on both workstations by start > run > dcomcnfg > expand component services > computers > right click on "my computer" > "default properties" tab > make sure enable distributed com on this computer is selected > default authentication level is "connect" and default impersonation level is "identity" > reboot if necessary

8.  Workstations have been rebooted.
