Re: NT 4.0 DHCP & Windows 2003 DHCP

Thanks for the reply.

They are on the same LAN Segment, not seperated. They don't have any
intention of of which server the clients get the address. (the servers do
have different scopes that don't interfere with each other). It just seems
that they cannot both be activated at the same time. For what reason, i have
no clue lol. I believe that even tryind to do this setup before removing the
NT servers is a waste of time as well. But this problem haunts me because i
have no clue whats causing it.

Are the domains separated by a router? If not then you have no
way of telling which computers to use the W2k3 DHCP server
instead of the NT 4.0 DHCP server and vice versa. The clients
send out a DHCP discovery packet on the hardware level to
find a DHCP server and obtain an address. With two DHCP
servers on the same segment you have no way of forcing a
paticular machine to use a paticular DHCP server.

We have a client who is in the process of upgrading from their NT servers
to Windows 2003. They want migrate everything together before they remove
the NT4 servers.

They are in a trust domain between servers. Now, they have a DHCP scope
on the NT4 server and a DHCP scope on the Windows 2003 server.. Scopes do
not interfere with each other address wise, however, it seems that when
one of the DHCP servers are activated, it automatcially deactivates the
other DHCP server, vice versa.

Has anyone experienced this or may know what could be causing it? Thanks
in advance.
