VBScript, Error 3 - Insufficient Privilege, Win32_Process.Create

I'm trying to execute a VBscript program which creates a folder on remote computer and then copies few files from the local computer to the remote computer, I'm using WMI Win32_Process.Create method to create the folder. The script executes fine on certain computers but fails on certain others with the Error Code: 3 and the description given on the MSDN site states as 'Insufficient Privilege'

I have a domain account which has Local administration rights on all the machines, so the privilege issue doesn't make sense to me.

We have a mixed environment of Windows XP and Windows 2000 Professional computers. The script executes fine on both the OS, so I guess it is nothing to do with OS architecture.

I have been trying to find a good solution to this problem but not successful. I have tried all sorts of things suggested like disabling firewall, firewall services, re-starting WMI service, enabling Remote administration etc. on few remote machines but still without success.

The aim of my actual script is to execute a Batch program which removes all corrupted installation of AV's on the remote computers and thats the reason I'm copying certain files needed for the uninstallation.

Any help would be much appreciated and also please suggest me any other means with which we could create folders on remote computers. The ai

Attached is the piece of code I'm trying to execute:
