Would like to change the DHCP duties from the router to the sbs 2003. Any tips when doing this, or should I just leave the router dhcp enabled?

    I think you must disable the other DHCP server, if the router is UPnP then I think that CEICW will do it for you.  As there is no way to indicate a prefered DHCP server I expect that keeping two servers creates unpredictable results.

    The DHCP setup was discussed earlier in http:Q_21727976.html

    Zadkin has it close... but to clarify...

    Disable the DHCP service in the router... then just run the CEICW (Configure Email and Internet Connection Wizard) on your SBS.  Running that wizard will go out to see if there are any other DHCP servers on the LAN and when it doesn't find any it will configure the one on the SBS.

    You will then need to reboot all client machines which can be done directly from the server if you like, either by entering separate "C:\>shutdown -r -m \\computername" for each workstation, or using SysInternal's PSShutdown:

    The question referred to above can help if you need to rebuild the DHCP service.

    I always recommend that you use SBS's DHCP instead of the routers because DHCP does much more than just handing out IP addresses.

    Thanks! one more quick thing: Should i use the exchange migration tool to move to a new sbs server if there is only ONE person using exchange on the old sbs?

    Well, that's an entirely different question... this had nothing to do with migration of an old SBS.  So, I'd suggest that you post it separately because it's not a simple answer.
