I'm having a very strange problem which I just can't get past.

The way our network is set up, we have 2 locations. The main office with all our PCs, and servers/ We are then joined to a local ISP via microwave link and they provide our internet gateway and house an additional storage server for us. All of the network infrastructure is within our office

The problem is...

When some PCs (and servers) are assigned IP addresses, they cannot ping the gateway or remote server however the remote server can ping the PC.

Most of our internal IP addresses work fine but specific ones (e.g. .29) has this problem all the time.

There is nothing else using the ip address and no other network problems. When we switch the IP on the PC, it works fine.

Please help, I'm going mad.

Thanks,

Steve
