File updates

[ROBERTS,DAVID N.]

1:   I have installed samba onto a number of VMS systems.  There have been a
number of cases where the VMS system has updated 
      the file, but when the file is opened on a PC, the file contains the
old data?  Any reason for this

2:  When I write to the Samba drive there appears to be a limitation on the
file size,  over 500K I get a unable to write to the file, drive 
     either full or write protected?

3:  We have stopped the system and restarted the machines, whilst NMBD is
shown as running we are unable to access the drive via   
     the network. 


Any ideas on the above.
