WFWG Setup Does Not Warn That PC-NFS is Not Supported (91201)

SYMPTOMS

During the installation of Windows for Workgroups (WFWG), there is no warning that the SUN PC-NFS network operating system is not supported.

CAUSE

Versions of the SUN PC-NFS network prior to version 5.0 are not supported by Windows for Workgroups version 3.1. If the references to the SUN client software are not removed before rebooting, the system may stop responding (hang) as the conflicting network device drivers attempt to load.

Normally, Windows for Workgroups issues a warning during setup if the currently installed networking software is not compatible with Windows for Workgroups. Windows for Workgroups version 3.1 setup is not able to detect the presence of a PC-NFS network.

WORKAROUND

To run Windows for Workgroups properly on a SUN PC-NFS workstation, remove all references to PC-NFS connectivity from the CONFIG.SYS and AUTOEXEC.BAT files or upgrade to PC-NFS version 5.0.

For more information on running PC-NFS version 5.0 with Windows for Workgroups version 3.1, query on the following words here in the Microsoft Knowledge Base:

Sun and PC-NFS and 5.0 and NDIS

STATUS

Microsoft has confirmed this to be a problem in Windows for Workgroups version 3.1. This problem does not occur in later versions of Windows for Workgroups as later versions support PC-NFS.
