There are two options for using a SAS Server from a workstation (assuming a SAS server has already been set up) :
1) Enterprise Guide, SAS's thin client software for working with a SAS server.
2) Foundation SAS, a "full" SAS desktop solution and SAS's fat client software for working with a SAS server.
Either way you need to request request the appropriate software and licence from SAS.

You appear to be confusing "server SAS" with "workstation SAS". Each version requires a different software install package and a different licence.
