Jeff,

this is how the network is identified by the DHCP
server and I am assuming you have pools defined for
every VLAN. Every pool again should have the default
router/gateway as the VLAN interface address.
all VLAN interfaces will have helper addresses
configured to point to the DHCP server.
I have tried this test with a W2K server on VLAN 1
with PCs on other VLANS with a NM-ESW-16 (etherswitch
module) which has the Catalyst IOS code on the Router
IOS...and it works!
probably a #sh run would help and also what is ur DHCP
server?
thanks
