Re: DHCP and Multipule IP subnets

["Michael J. Lewis" <[e-mail]>]

We've tested NT DHCP on a multi-homed server (Ethernet and Token Ring) 
without difficulty.  We have not tested with VLANs.  The only trouble we 
had was that when we put in the second card, routing was enabled on one 
card and not the other.  This produced some wierd TCP/IP behavior and 
prevented DHCP from working on the Token Ring side.  Disabling routing 
on both cards allowed DHCP to work correctly.

As far as defining scopes, one simply defines one per segment.  

Regarding VLANs, I've read that setting your VLAN by IP address is 
incompatible with DHCP because the workstation is unable to determine 
which LAN to join if it doesn't have a TCP/IP address at start up.
