Hi,
A few possible sources of problems connecting remotely with WMI:
1. Both computers must have the WMI service.
2. You cannot connect to a computer running XP Home.
3. An NT computer cannot connect to an OS later than W2k.
4. A W2k3 computer cannot connect to Win9x (even with WMI installed).
5. To connect to W2k Server SP4 and above, you must set impersonationLevel
(you have).
6. W2k computers must have SP2 or above to connect to XP or above.
7. W2k3 can only connect to Win9x or NT if credentials are supplied.
8. To connect to XP or W2k3 you must set authenticationLevel to Pkt.
Obviously I've struggled with this as well. Someone else may clarify, as I
notice that points 4 and 7 seem to conflict, but you get the idea. Your
problem might be solved by specifying packet level authentication (point 8).
For example:
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate,authenticationLevel=Pkt}!\\" _
& strComputer & "\root\cimv2")
Or, you may need to apply service packs. Let us know how it goes. For more
tips, these docuents are useful:

Also, if a firewall is the issue, this might help:

I'm using a script to check the current logged on user on a remote
machine.
The basic script that checks the logged on user works it is not using the
supplied credentials. Below is the script in its entirety. I am using a
template from the script center to do this. I'm pretty sure that the "Set
objWMIService" is the source my my problem but I don't know how to get it
to
work. Can someone shed some light on how this should work. This script
will
be for my helpdesk.
