From this morning we've had around 6 users complain that they are not getting a network connection. On further investigation the device is getting an IP address and can be pinged locally but is unable to get off the site.
On checking the ARP cache on the 3750 the devices not getting off the network all have Incomplete next to there addresses, I've flushed the cache a number of times and it still comes back incomplete.
The devices plug into a 2950 which is connected to a 3750 that does all the routing off the LAN and its from the 3750 that we cannot see the devices in question.
Any help would be much appreciated.
