OK, not strictly an automation question, but in the idiotic trend towards PCs in control relevant all the same.
Besides I have exhausted all the other avenues of help that I know of.
I have never had any problems networking two or more windows machines on a peer to peert network from W4W, through Win9x to Win NT4. My problems start with Windows2000Pro.
My Win2K notebook networked perfectly well with my Win98 desktop. When I upgraded the desktop to Win2K I could not network the two. There appeared to be a Master Browser conflict (see the event log below).
Recently I added a Windows XP machine still no network access. TCP is installed and working properly, the adapters and their drivers are shown as working. In both cases I can ping the loop back address and the local adapter address succesfully, but cannot ping the other host.
The Event logon the Win2K machine shows the following entry
Event: 8003
The master browser has received a server announcement from the computer LONDONBRIDGE that believes that it is the master browser for the domain on transport NetBT_Tcpip_{439C10FE-6053-4. The master browser is stopping or an election is being forced.
The registry entry shows that Master Browser selection is set to automatic.
The WinXP machine didn't have any relevant event log entries originally but now it is showing the following two entries which may be relevant but are probably caused by my attempts to fix the main problem.
Event: 29053
IPRIP could not join the multicast group 224.0.0.9 on the local interface with IP address 10.1.1.128. The data is the error code.
Event: 7000
The RtlPacket service failed to start due to the following error: The system cannot find the file specified.
Each of these two machines will only see themselves in the network browser. I added a third node an NT4 machine which displays all three machines in the browser, but cannot connect to the other machines.
The NT4 machine can connect, no problem, over ethernet via the common hub to a ControlLogix processor when it is connected. So the hub is
working.
I have run the automatic network diagnostics in XP, this showed no problems (I can supply the result log if anyone is interested). I have
contacted various supposed experts on the net and the seem to be as stumped as I am.
Workgroup:CSNL
Node: 10.1.1.4
Name: elephant
OS: Win2K Pro
Node: 10.1.1.128
Name: londonbridge
OS: WinXP Pro
Node: 10.1.1.251
Name: sales
OS: Win NT4
If I try to access the NT4 machine from the WinXP machine (by doing Find/Computer \\10.1.1.251 or \\sales ) then both LEDs on the hub flash. If I try to access the XP machine from the NT4 machine only the NT4's LED flashes).
So the IP address resolution has failed so what is the problem?
I would be grateful for any help.
Regards
