Cisco 1720 Ethernet Port intermittently going down

I have 2 1720 routers. One is in Massachusetts. The other is in West Virginia. When a server in WV attempts to ping the MA router, no problem. When a server in MA attempts to ping the WV router, request time out messages appear. The problem is resolved by performing a shut and then a no shut command on the Ethernet interface. Operation works for a few hours, then the Ethernet interface drops connection again. I would like to know has any one seen this and what the resolution might be. Help would be much appreciated.

The 1700's I've worked with have a rather high failure rate on their Fastehthernet ports (about 1 in 8). If it's not a cable or hub/switch problem (check for errors in sh interfaces F0/0), try another router if you have spare.

Also, try experimenting with the port's speed and duplex parameters.

When the problem is happening the the router in WV and see if it has a route to the network in MA where the server is located.
