I have a small problem that I'm hoping somebody can help me with. I know that the answer is something simple but it hasn't really hit me yet, so I'm looking for some inspiration!! It goes like this:
I recently left a small company to join a much bigger one. My old company has a small network of 4 nodes and an ISDN router/gateway. I frequently e-mail one of my colleagues there and we fire mails back and forth all day long! Today he rang me to tell me that he couldn't get on the network, and therefore couldn't get his mail or get on the web!! I did the usual thing, ran through some settings, pinged the gateway ... nothing!! So, I went down there on my lunch hour to have a look. I checked the gateway (forced a test connection), tested other PC's .. everything was fine. However, this one PC can't get on the network and can't ping any other PC, mail server or the gateway. I checked, double checked and re-configured TCP/IP. Checked the IP address, subnet mask, DNS servers, gateway, bindings, client for MS networks, file and print sharing .. all the usuall stuff!! Still nothing. Re-booted, logged on to Client For MS Networks, tried pinging .. nothing. I checked the lights on the back of the network card. They were on. I checked the light on the hub. That was on. Still nothing. However, the thing that I beleive is causing the problem is this:
If I ping the gateway or the mailserver (or whatever) I get activity on the hub .. but the collision light constantly flashes whenever I'm pinging from this PC. The collisions must be causing dropped packets and the "request timed out". There are usually a few collsions but this is constant whenever this PC is pinging. I swapped the fly/patch leads and even changed the port on the hub. Still the same.
I feel sure that the answer is staring me in the face but I just can't see it and I really don't want to spend my whole weekend at my ex-companies office!
Any suggestions?
Chris.
