    Hello,
    
         One of our customer is having big network as shown in the figure.  
    There are around 250 PCs connected on the network.  Mainly Pathworks
    File and print services, VMS mail services are used by users.
    
         The growth plan is around 100 PCs every year.  I would like to
    have some suggestions how improve the network with minimum changes to
    existing network structure.
    
         If this is not correct notes conference for this query, please
    advise which is the correct notes conference to put this query.
    
    Thanks inadvance and regards
    P. Malakondaiah
