Do you miss the Winsock 2.0 Management option in the NRM portal on NetWare 6.5 which existed on 6.0? If so, it still exists and is just hidden by default.
Load your portal.nlm with the /WS232 option. The switch IS case sensitive. Once you've done this the Winsock 2.0 menu will be available in NRM.
Comments from Support:
Note: Once you load the portal with the switch, the Winsock Management option appears under the Manage Applications section.
