(Similar to the post earlier) I've got a NW5.1 server that runs
BorderManager 3.8 and DHCP only. (DNS is handled by our ISP).

We have 7 other NW servers - all 6.5.3. Is there really any reason to
move the DHCP from the NW5.1 serer to one of the 6.5 servers? I
haven't noticed any problems - but - I wonder if things would be
better if DHCP was on one of the newer 6.5 servers. Thank you.
