Hi Fidelis !

Few months ago I did successful installation of entire my Oracle stuff for Windows on LAN server. It included SQL*Net 2.0, Oracle TCP/IP Adapter, CDE Tools, Oracle Book 2.0, Oracle Data Browser and SQL*Plus 3.1. After some trials all of mentioned above connected to remote Oracle Servers successfuly.

Few thoughts about configuration I have implemented: - all clients start their own Windows at their workstations (if use Windows LAN installation, make sure all clients start Windows from the same installation),
- all Oracle networking DLLs are on LAN server - the DOS PATH must include directory ORAWIN\BIN on LAN (AUTOEXEC.BATs are adjusted at each workstation), - ORACLE.INI resides on LAN,
- the section [Oracle] and parameter ORA_CONFIG pointing into common ORACLE.INI included into WIN.INIs of all clients,
- ORACLE.INI parameter ORACLE_HOME points to the ORAWIN directory on LAN, - LOCAL = TNS:dbase, where dbase is the alias of a database most often connected to included in TNSNAMES.ORA,
- TNSNAMES.ORA resides on LAN directory ORAWIN\NETWORK\ADMIN, - definitions in TNSNAMES.ORA contains no hostname aliases - only numeric IP addresses are used. If using hostname aliases, make sure that all clients have accesible HOSTS files and there are IP addresses for each hostname used (as far as I remember TCPIP.EXE of Novell LAN Workplace must be started in directory containing NET.CFG; this file must contain following definitions:

        Protocol TCPIP
               PATH TCP_CFG directory

where directory points to the place where HOSTS and SERVICES reside), - VSL.INI is copied to WINDOWS directory of each workstation.

Hope this helps !
