Remove IPX/SPX and make sure that you have set static IP addresses for both machines. Try 10.0.0.1 for one and 10.0.0.2 for the other and use a subnet of 255.255.255.0.

Now test it and let me know!

Unless you actually need TCP/IP for applications, I'd just use Netbeui for this little network, removing TCP/IP.  It will work fine as long as you don't have to go through a router for some reason (like ISDN).  

Is the hub a 10/100 auto switching?  You may want to check the cards themselves, some have an option to force it to use either 10 or 100 (check documentation).  I've seen this either make the NICs not work at all or "crash".  I take it you're using MS F&P sharing when copying files?

If you need TCP/IP, do both computers work fine using TCP/IP (ie. able to use the internet?).  Otherwise your TCP/IP stack may be toast on either machine (winsocks).  Good luck...

Here's all the private IP ranges:


10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

i need the ipx to run some netwrok games that are fine. I have the same problem with the protocal removed temp anyway, i have the net mask at 255.255.255.0 and the ip on 192.168.0.X where x changes on each machin. does this help

Try ping the localhost on both machines to see if you get any errors.  Click Start/run/  type in command.  & type "ping localhost" w/o the quotes on both machines & see what happens.  If you get an error, you winsocks are more than likely toast.  If this works on both machines, try pinging the "remote" machine.  like "ping 192.168.0.1" or whatever.  See what errors you get if any...e-mail me for a quicker response.  I'll be online for a little longer today...

1) Is there anything you actually need TCP/IP for on this little network?  

2) More than likely the cabling is OK...games usually send a lot of data across...it doesn't hurt to try though, you are using CAT5 right?  If using anything less, try the CAT 5.

3) What were the ping results from the command prompt.  I take it the other "ping" you were talking about was through the game using IPX right?.

1) Does it work w/o TCP/IP?  Just curious.

2) Does it work w/o being connected to the 3rd machine?  Possible misconfiguration with the firewall?

3) Does TCP/IP work with the internet on each machine?  Do each of them have a modem as well?

4) What type of 3com NIC is it?  Model #?

5) How are you copying files?  Through microsoft file & printer sharing or through FTP or other method.  May want to try it through FTP if F&P sharing isn't working.  You want to try narrow the problem down as much as possible.

kplonk, is that 3rd machine a Win98SE box? or are you using Linux? If it's Win98SE, than use DHCP for the IP addresses.

By the way, can both machines browse each other in Network Neigbourhood?  Do the directory share already created and make sure the service "File and Print Sharing for Microsoft Networks" has installed, (make sure not "File and Print Sharing for Netware Networks").

Goto Dos Prompt and type: net view \\(your 2nd computer name or ip address), make sure the destination directory is available for copy. Then try again!

for get the third box
the problem is between 192.168.0.2 win98
and 192.168.0.3 win 95 both have the same network card and have client for microsoft networks and file and print sharing also for microsoft networks.install, bot have the tcp/ip and ipx protocal instaled as well. I can see both machins if i go to network neighobour hood and also brows there drives (this is slow) and i can select and copy files the problem is speed. the cards and the hub are both10Mips anf the cable less than 2M a side and is cat5. Does this help?

Okay, let's look at it another way. Let's refer to the two machines as PC1 and PC2. If you transfer files from PC1 to PC2 it crashes. How about transfers in the other direction?

Personally, I would take those 2 NIC cards and sell them. Then get 2 PCI cards and install them.  With the ISA cards, if you have an IRQ conflict then your network may look like it is up and running, but it actually isn't.  The PCI cards are much more Plug and Play and work better with IRQ sharing.  I know that this may not seem like the best answer to throw money at it, but I believe it to be your best option...
Hope this helps

Is it possible to load one protocol only, e.g. IPX and test the copy in both way.  If it works add another protocol e.g. TCP/IP (I'm not sure do 192.168.0.x will work, try 192.168.1.x instead).

Please let us know your result in each stage.

If it's in both directions, then it might be the hub. Doom etc don't send sustained packets, but a transfer would be.

what transfer rate would you expect from my main machine pII450 and the like to the 486 on 10mps network as described above

If the network components such the cable, NIC's, hub etc are at their optimum, you should see transfer rates up to 10mps subject to the write ability of the 486.

Okay this is going to sound silly, but you say slow connection, but define that. There's variables to deal with here, such as the memory and read/write capabilities of that 486 box.

well i have a dx2 66 20mb ram 3com 3905 10mips cards and a kingston hub all conected useing screend cat 5 cable. the drive in the 486 is a quantum fireball 512mb running win95. does this help. I think that 1mb per min is slow how do you feel.

IMB per minute is slow, but all of that 486 equipment is legacy. 20MB of memory and a 512MB hard drive would be the greatest of the problems right there.

In another turnaround and just want to making sure everything are in good condition. Do you have spare for that UTP cables? I've experienced that the connection was established but unstable because of the cable wires assignment were wrong.
