Does the workstation have access to the server? Is a firewall running on the server? If you have an IP of an internet host (such as www.yahoo.com) can you ping that address from either the server or the workstation? We need to narrow down the possible points of failure before an exact fix can be provided. It sounds like a possible problem with the firewall not doing NAT and forwarding of connections, but I do not know if your server even has internet access. It also could be related to DNS or several other things.
