TCP/IP Route problem ?

[JimDoddery]

Have a problem...don't know too much about TCP/IP...

Have 3 boxes: 10.179.20.8
10.179.20.9
10.179.20.10

3 boxes are patched directly to a switch that carries an IP address of 10.179.24.4.

Boxes can talk to each other with 1 hop, ( host to host ), but intermittently stop communicating. Switch ports and NICs on servers are all configured to 100/Full. The 3 servers are default routed to 10.179.0.1.

Anyone see any errors in here ?

Out of interest, what subnet mask is defined on the servers and the default gateway (10.179.0.1).

Given you have intermittent IP routing issues only, it's unlikely the problem you have is with your IP addressing but with something more fundamental.

Things I'd look at include:

1. Check/replace physical cabling.
2. Check/replace switch and/or switch ports
3. Check physical switch ports and interconnecing switch trunks for errors.

Your intermittent problems are probably a totally separate issue. What OS is involved?

I don't know much about all this but
could it be a problem with computer names? non-standard names might cause problems according to a message
I got in XP when using an "_" char in the name of one of my computers.

your issue is that the ip numbers place themselves on different subnets

you should use the same numbering

IP address of 10.179.24.x

10.179.24.x (not 20.x)

otherwise you must somewhere have a route path from 10.179.24.x to 10.179.20.x

subnet mask is "?? 255.255.255.0 ?

The switch IP address is irrelevant to the problem at hand, as is the default gateway. The boxes are on the same subnet, so if they intermittently lose communication you need to look at the configuration on the boxes themselves and/or the switch ports.

When you say that they lose communication, what exactly are you talking about? Is it a certain application that stops responding? When this loss occurs, can you even ping from one box to another? Does this problem happen to all three boxes at the same time? When the problem happens, what do you do to temporarily resolve it?
