To connect through TCP instead of Named Pipes and Winsock network protocols, you must enable the TCP connections:
From the Windows task bar, select Start | Programs | Sybase | OC OS Config.
Click the NetLibrary tab.
Select Windows NT or 98 as the platform and TCP as the protocol.
This process maps NLWNSCK to TCP in your Sybase network configuration file (libtcl.cfg).
You have completed installing Adaptive Server client plug-ins. To find out more information about setting up network communications, or to add optional functionality to Adaptive Server, see Configuring Adaptive Server Enterprise.
After you have installed the Sybase products on your system, see their accompanying documentation for configuration and administration issues.
