We thought it was about time to start migrating our NT 4.0 Domain
enviornment to new hardware and Win2k3 Active Directory. (so we can
complete an Exchange 2003 environment).
We thought the best method, was to migrate the DHCP and DNS servers
first to Win2k3 servers.
We've installed our first Windows 2003 Standard Server, Applied
Service Pack1 and added to our NT 4.0 Domain and installed DHCP, WINS
and DNS.
We've followed the articles at Q325473
http://support.microsoft.com/?id=325473.
Made sure we've jetpacked the database, exported the database using
the Dhcpexim.exe utility.
Imported this database into our Win2k3 DHCP server, all went well with
no error. Using netsh the command completes successfully.
On checking the Win2k3 DHCP server, all the information appears
correct, the sceop is Active and labelled correctly as in NT 4.0,
server options are correct, Scope Reservations appear correct, and
lease information is still valid.
One issue which we immediately noticed, if we try and delete a DHCP
lease in Address Leases the error message The following error occured
when trying to delete the record "The parameter is incorrect".
and we cannot delete any DHCP Address Leases, no error is observed
when trying to delete a Reservation.
The other bigger issue is this DHCP server is not leasing DHCP IP
Addresses to any client Win2k servers, XP Clients, NT 4.0 Servers. No
errors are present in event logs or dhcp logs.
If we statically allocate IP addresses it works.
We've gone back to the NT 4.0 server, reconciled the database, removed
all the active leases, jetpacked, exported and tried again, same
problems as above.
I've been reading about Authorisation, but this is depedant upon
Active Directory, and we are not there yet? Read about workgroups and
DHCP servers for Win2k3?
Is Win2k3 DHCP supported in a NT 4.0 domain environment?
or should we build DCs first and then migrate DHCP & DNS.
