Date: Feb/05/93 Solaris Release: SunOS Release: Unbundled Product: PC-NFS Unbundled Release: 4.0a Topic: Correct print server subsystem BugId's fixed with this patch: 1110994 Revalent Architectures: i386 NOTE:PC Patches which conflict with this patch: Obsoleted by: NOTE:PC-NFS 5.0 Files included with this patch: patch.exe, readme.txt Problem Description: Patch resolves certain problems with the print server subsystem in PC-NFS 4.0a. These problems include hangs and performance degradation under heavy load. The problems occur more frequently with certain Ethernet NDIS drivers. INSTALL: Patch 100648-01: - Patch 100648-01 is a prerequisite and MUST be installed first! This Patch: - In the directory where PC-NFS is installed (typically C:\NFS) perform the following copy commands: copy lpd.exe lpd.fcs copy lpt.exe lpt.fcs copy pcnfslpd.exe pcnfslpd.fcs copy prtserv.msg prtserv.fcs copy rtm.exe rtm.fcs - Copy PATCH.EXE into an empty directory on you PC - PATCH.EXE is a self-extracting archive. CD to the directory on the PC where you copied PATCH.EXE and execute it by typing "PATCH". This will unpack the following files: Length Method Size Ratio Date Time Name ------ ------ ----- ----- ---- ---- ---- 46718 Implode 28484 40% 12-23-92 19:39 LPD.EXE 62434 Implode 36949 41% 12-23-92 19:39 LPT.EXE 7504 Implode 3207 58% 12-23-92 19:39 NFS-NDIS.SYS 30595 Implode 19288 37% 12-23-92 19:39 PCNFSLPD.EXE 14480 Implode 3287 78% 12-23-92 19:39 PRTSERV.MSG 32341 Implode 19956 39% 12-23-92 19:39 RTM.EXE - Copy all of these files except NFS-NDIS.SYS to the directory where your PC-NFS is installed (typically C:\NFS.) - If you have configured PC-NFS to use NDIS drivers, copy the file NFS-NDIS.SYS to your LANMAN directory. (This is normally C:\LANMAN - check this by examining your CONFIG.SYS file and looking for the line which loads NFS-NDIS.SYS.) - Reboot and test your system. - The readme.txt file contains additional information about this patch and a new heuristic within NFS-NDIS.SYS which may prevent hangs with some vendors NDIS drives when activated.
