When installing the SAS PC File server it defaults to using port 8621.
But if you have the SAS Stored Process server installed in SAS 9.2 it also uses port 8621.
So when trying to start the SAS PC File server as a Windows services it won’t start.
To change the port, open the SAS PC File server via the Desktop Start menu Shortcut.
Was about to type this up in full but found a SAS Support note instead
