    I have a current network (Win2K) that does DHCP etc for all
    computers that connect to my LAN. I would like to upgrade the Win2K server to
    SBS. Only about 5-10 of the computers on the LAN are my (my staff's)
    computers, while all the other are connected simply to get access to the
    Internet (web, their company email hosted elsewhere, etc.).

    My question is whether or not there is a limit to the number of computers
    that can connect to my LAN and get an IP from the DHCP server? Again, only 10
    at most of those machines will actually be joined to my
    domain and use the SBS resources (Exchange Server, IIS, etc). All the others
    will simply get an IP address and access to the Internet.

  2. AFAIK, there isn't an SBS limitation on this. You don't say how many 'other'
    computers there are, but probably it's less than the default SBS DHCP
    configuration would allow and even if it's not, you can change that.

    But if it were me, I'd redesign the network somewhat. Two nics in the SBS,
    with the SBS internal nic connected to a switch with the SBS client
    machines, and the external nic sharing a port (but with a fixed IP) on a
    DHCP enabled router for the 'other' boxes - both sharing the same internet
    connection. You should be able to do this for less than $200, and it would
    provide much better security for your SBS network, seperating it from the
    unmanaged workstations.

    Thanks Les. My situations is somewhat complicated by Cisco Call Manager and
    lots of switches, routers and firewalls, but I understand your concern
    regarding the unmanaged machines. I was trying to save some time by upgrading
    the server I have in place. I guess I'll either move the DHCP to my router
    (and then upgrade my current server) or get another server (which I have to
    do eventually since my current box is a bit long in the tooth) and set up a
    separate VLAN for my (my staff) computers: can give them a different NAT IP
    as well so my Exchange Server IP doesn't get blacklisted should one of the
    unmanaged machines start spewing email due malware, etc. Number of hosts
    would not be of any concern in this case.
