How do I get a list of logged on PC's on an NT4 network?

Thanks in advance.

Before you buy.

1. I think you may need to be in the local administrators group of the PC's
in question.
2. It's a good idea to ping them before trying to get the usersnames from
them
3. It will show the last logged on users not just ones currently logged
on... so if the policy is not set to clear 'last logged on user' info the
responses may be no use and if the PC's are hardly ever rebooted it may not
help much!

Other than that it should take about 5 minutes to detail around 800 PC's.

The good news is I'm hoping to post some code/program/both as freeware or
shareware doing this and a lot more on the internet in the next few months
when the software has passed some more beta testing and improvements.

Found a working example of NetServerEnum on Microsoft Knowledge base
article Q198896 at

http://support.microsoft.com/support/kb/articles/q198/8/96.asp

and also an example of NetUserEnum in Q159498 at

http://support.microsoft.com/support/kb/articles/q159/4/98.asp

which were easy enough to convert to my needs.

If the machine is configured NOT to broadcast itself in the browse list,
then NetServerEnum would not find those systems.  The last assignment I was
on disabled file/print sharing on some of the NT workstations.  Even worse,
sometimes Servers would not be displayed properly in the Browse(Network
Neighborhood) list ('quirky' situation).

I had a similar problem.  In the case listed above, they gave me the IP
segment #'s for the entire network.  It took a longer period of time but, I
used NetServerEnum on each domain and dumped the names to a database table.

After that was complete, I PINGED each system from the database table and
retrieved the corresponding IP Address.

Using the IP Segment #'s, I PINGED all remaining IP addresses.  If I
received a reply, my program would do a reverse-lookup (IP-to-ComputerName)
and would place that information in the database table.

Again - this may not be necessary in your situation but, you may want to
keep it in mind.  Especially if you have a 'quirky' environment like my last
assignment.
