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.
