Group Policy?

http://support.microsoft.com/kb/816102

I am trying to deploy the registry settings on windows 2008 server remotely..
While executing thru PSEXEC from any windows xp or 2008 server it shows access denied...

created a batch file as below

@echo on
net use p: \\x.x.x.x\foldername
copy p:\xyz.reg c:\
reg import c:\xyz.reg
net use p: /delete
exit

If all you're doing is registry changes, just use group policy: http://technet.microsoft.com/en-us/library/cc753092.aspx

That's much easier to manage.

My approach for GPO was primary but due to mix environment of servers ( Windows 2003, 2008) in same OU which is making tough time..
My only target is windows 2008.. also i am using psexec 1.98 version.

Thanks

Tried appying WMI filter on GPO for windows 2008 platforms
Please help me to verify the below query is incorrect

Select * from Win32_operatingsystem Where (caption Like "microsoft Windows server 2008%)
Select * from Win32_operatingsystem where version like "6.1%" and (producttype = "1" or producttype = "3")



thanks
