'csf' can you ping the server from your workstation
c:\> ping MyServer
I have a feeling that you can not see the server by its user friendly name. Can you ping it by it's IP address.
c:\ ping xxx.xxx.xxx.xxx
If so, then use the Client Network Utility for SQL Server and define an Alias to this server. Set the network library to TCP/IP, set the server alias name to the server name and enter the IP address for the server name.
