Determining IP Address Remotely

I am wondering if there is way (as well as an app or utility) for determining what IP address a networked computer is using. I know how to do that with computers within the same subnet (using Ping) but is there a way to determine a system's IP address that is NOT in the same subnet?

Specifics:
SINGLE DOMAIN (NT with some W2Pro workstations mixed in)
PROTOCOLS installed on all workstations: NetBEUI & TCP.
DHCP enabled on most of the workstations but there are some setup STATICALLY (with no gateway to the Ineternet) that I can't discover IP remotely on. I would like to do this while user is logged on.
I thought "PSLOGGEDON" from Mark's Sysinternals would do it but it only gives who is logged onto the system, not their IP address.

Thank you very much for any help on this!

ADDENDUM:

Oh, and of course I'm wondering also if there is an app/utility that will allow me to CHANGE the IP address of a networked computer. BTW, PDC has only NetBEUI installed - no TCP protocol. (DM didn't want TCP installed on PDC).

for the workstations using tcp/ip, tracert machine name
this will tell you the rout, and the ipnumbers.

for dhcp you can change the ip remotely, for all by getting the server to send reset signal, forcing the pc's to get new ip.

the only way to change remotely on static ip is to have remote login as admin, edit the ip config.

This is the problem. All workstations are on same SEGMENT and all have NetBuei installed. I THOUGHT I used to be able to ping them before but now I'm not sure (it's been so long). While I was absent, somebody setup some workstation with ROUTABLE IP in spite of fact that DM (Decision Maker - Boss of company I support) demands that they not have Internet access for users AT ALL. Thank you for the info about NETSH but I don't think it works when you have mixed in NT workstations and it those ws's I need to deal with.

NetBeui isn't routable. So if the workstations aren't in the same segment, and there is no TCP/IP bound to the PDC, how exactly are clients in another segment reaching it?

Provided that you are incorrect and that the PDC does indeed have TCP/IP bound to the NIC and you have a functioning WINS server, then you could use the NBTSTAT -a computername to derive the IP address. You could also just look in the WINS database for it.

by kahunanui

No TCP/IP bound whatsoever. We are dealing with the same segment.
No routing needed. Thanks

NBTSTAT -a computername <--this command will also tell you who's logged (if anyone is logged on)at the moment. So it should be your solution. However, you will not be able to change the IP address with it. I don't think people use IP reservations enough. So maybe that would be your solution.

I ran into the same problem with one of my networks and I hope this is not advertising; But I ran into a utility called EZDNS and it emails you LAN and WAN IPs :) Hope this helps, Los

Since those systems do not have access to the Internet, I don't know how this would help.

by kahunanui

Since these workstations don't have Internet access I fail to see how that would help. Thanks anyway.
