vbscript to install a .msi file

I am trying to come up with a script to install a .msi file on 100+ machines.
I found the below from activexperts.com but keep getting an rpc error. I know it is becuase I am not using correct syntax....

The error is on line 3.. What should be the value for Set objConnection???

Const wbemImpersonationLevelDelegate = 4
Set objWbemLocator = CreateObject("WbemScripting.SWbemLocator")
Set objConnection = objwbemLocator.ConnectServer _
("WebServer", "root\cimv2", "fabrikam\administrator", _
"password", , "kerberos:WebServer")
objConnection.Security_.ImpersonationLevel = wbemImpersonationLevelDelegate
Set objSoftware = objConnection.Get("Win32_Product")
errReturn = objSoftware.Install("\\atl-dc-02\scripts\1561_lab.msi",,True)
Wscript.Echo errReturn

Thanks for any help

Try this one instead (specifically the "Script to Create (Start) a Process on a Computer"):

Works like a charm

How does it know where the .msi lives to execute on the remote machine

I was also able to get the first script to work, but it you have to mess around with dcom on the PC sourcing the MSI.

On the MSI source
load dcomcnfg
Expand Component Services\Computers\My computer
Right click My Computer and select properties
Select the COM Security TAB
Select the Edit Defaults of the Access Permissions
Grant System Remote Access.

;new vbs file
strcomputer="some machine"

Const wbemImpersonationLevelDelegate = 3 ;not change to 3 from 4
Set objWbemLocator = CreateObject("WbemScripting.SWbemLocator")
Set objConnection = objwbemLocator.ConnectServer (strComputer, "root\cimv2", , , , "kerberos:" & strComputer)
Wscript.Echo "Error: " & Err.Description
objConnection.Security_.ImpersonationLevel = wbemImpersonationLevelDelegate
Set objSoftware = objConnection.Get("Win32_Product")
errReturn = objSoftware.Install("\\MSIsource\share\some.msi",,True)
WScript.Echo(errReturn)
