Problem Description: 

1092809	   Problems opening more than 64 unique files on a network drive. 
   &       Patch increases the limit on unique files open at one time to
1094757    120.  This is the total number that can be opened on all NFS 
           drives, not the number that can be opened on each drive.  Open 
           directories below the root directory should be counted as open 
           files.  The /f parameter on pcnfs.sys allows a maximum of 127 
           files to be opened, however, only 120 unique files may be opened.

1128058    Problems using net use with the cdrom switch on non-sunos systems.
	   Filenames are not remapped properly.  With patch you can access 
           raw file names from NFS mounted CD-ROM's from DEC Ultrix and HP 
           Unix servers without file name remapping.  Mount the CD using 
           net use /cd.  The /cd switch should be used only on CD's whose 
           filenames would normally be remapped.

1131811    Remote CD-ROM access via Windows for Workgroups displays the first
           directory but nothing else on the CD.

1135359    PC may cache small writes rather than flushing it to NFS mounted 
           disk.  Problem may lead to data corruption if muliple users read 
           the stale data.

1372145    Fixes a problem with CD-ROM access when the CD-ROM is attached
	   locally to the PC.

1153350    Word6.0 cannot create or edit files on a network drive mounted 
           with the /mustshare switch.
