vmware has two types of networking that you are probably very aware of:
bridged and host-only. Providing you've setup bridged networking as
expected, and it still doesn't work, the only answer is that they *have*
direct MAC -> IP addresses settings in the DHCP server configuration.

There's other things to consider too. If you're using one of those funky
secure switches, it may be that the switch has port security turned on,
which disables the port if the MAC address is not that of the one it's
expecting. Since vmware creates a special MAC address for the virtual
network bridge, this could be the case.

HTH,
