can't access server

Hi, I'm having problem with a workstation connecting to the Server's SQL
Server. The workstation can access the server's hard drive via share and
TCP/IP seems to be working. But the workstation just can't access the
server.
how to tack it down? Thanks.Hi
What is the error message?
Regards
