Network Tests...

By PeeJay ·
To whom it may concern:
I came into work today and for some reason some buildings on our network weren't communicating. I was really just wondering of some tests to run and what should I do if the buildings are not responding to each other. (It's an NT 4.0 Network.)

Thanks

Hopefully you use TCP/IP with routers between buildings. If that is the setup try to ping the routers. If the routers are not responding telent to the last reachable and run a Sh Ip Rou for the next subnet. If the routn is there run Sh Cdp Ne.
This will tell you what routers are conected.
Hopefully this helps.

To some extent it depends on how your buildings are linked.

If the phone company is doing it for you, check their equipment for power and connect lights. If you don't have the light pattern you have come to expect, call for service.

If you link your buildings with FDDI or CAT-5, check the hubs at each end of each connection. Are the hubs powered up, and do you have a green light at each end for the connection of the inter-building link?

For each inter-building link that seems to not work, if you are getting lights on the hub, find a station plugged into that hub at each end, and see if those two stations can ping each other. If so, the link is up, and the problem is elsewhere. If not, your problem is the cable or one of the two hubs.

For FDDI, you should have monitor lights on the fiddi connections at each end.

Moving along your network, for each hub, pick a station and make sure you can ping and connect to the server. When you move out by one connection and can no longer connect, carefully examine EVERYTHING between the station that worked and the one which did not. That connection has a problem.

Good luck.
