computers in a network

How do I get a list of the computers on my network? I've looked through some of the other threads, and the suggestions there seem to work fine for WinNT, but I don't even get my computer to show up on WinME. Is there a way to do it with WinME or Win98??

is it possible that I have stumped everyone?

I'm trying to make a modified version of WinPopup, with the names of all the computers on the network available, instead of having to know each one. But this information is useless if I can't get it.

'Here it is AGAIN
'This will get the network name and all computers booted to the LAN
'Paste this into a module

Is there any simple way??

What can be more simple for you, than copy/paste this code?

I'm using that code, but I get varying results. What computers on the network does it find? I get unix servers, NT servers/clients, but it doesn't always return computers that I know are on our network. Sometimes it shows my own PC on the list, other times it doesn't.

I think I've found the problem, the buffer size is not large enough. I doubled the buffer size and got twice as many results back.
