Background.
I have been tasked with doing an estate discovery of windows servers
within some domains.
I have a list of domains, and know that the estate contains a mixture
of Windows NT4 and Windows 2000 servers and workstations.

I have started to develop a WMI script, of which I am new too. The WMI
script basically does the following:

Try to ping the device in the domain
if Ping is successful then get the following info
     OS
     OS Version
     Role (i.e. Member Server or Member workstation or Standalone or
Prim DC  or etc...)

The problem I am having is that when the code discovers a NT4 server I
can ping it but cannot get any info. I believe this is because WMI is
not compatible with NT4. Is there anyway around this? i.e. use some
WMI that works with NT4?

I also have the following issue. I am denied permissions to run my WMI
on some servers (e.g NT5.1), but when I go into server manager (as the
same ID) I can view the properties of the server. I have been told
that if I can do this in server manager, then the WMI code I use
should be able to run my queries. This is not the case.

I would have attached the code but am having problems getting it
outside my mailchecker!!

Thanks for any help

PS
Are there settings that can prevent WMI running (on NT4 or NT5x)? What
are they? Can I view these using WMI?
