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.
