Thanks, that didn't work.
I checked my network to confirm the IP address and it is up and running and I can see both my Mac and the Linkstation. Both are active (online) and both have IP addresses. However, of the two PC's I have on the network, one accesses the Linkstation very easily and i can see all of the folders. However, now the second PC sees the Linkstation but when I try to access it I get the following message "Could not open shared file, confirm drive status". What is up with that?
