Windows 2000 to Windows 2003 migration using ADMT

Active Directory
Microsoft Windows
SQL Server
I have a single domain network that I run with only one computer running AD on Windows 2000 server sp4. Unfortunately the hard drive is dying and I am setting up our new PDC on a Windows 2003 server in a new forest and was hoping to use admt to migrate the user accounts with SID's over to the new server to make the move a little easier. I have never used admt before so I have been following documentation on Microsofts website and heres the trouble I ran into over the weekend. First does it matter whether you run admt on the source or target PDC? Everything I tried so far has been done from the target PDC b/c I'm trying not to use the source PDC too much b/c of the hard drive. Second I've tried to migrate the passwords but it keeps saying that it can't find the password export service on the source PDC (but I can do w/o the passwords if I have too it's the SID's that I really need). So I continued on and it said that it couldn't verify whether auditing and tcpipclientsupport was turned on. Access denied. I have the trust setup and validated, I have auditing turned on like the doc. said, I am running admt as administrator, but when I go to the HKLMSystemCurrentControlSetControlLSA field on the source PDC there is no tcpipclientsupport key. I hope I've given you all the information you need and any help would be greatly appreciated as I have no idea how much longer this hard drive will last. Thank you!

Thanks. We'll let you know when a new response is added.

Why not simplify things and just install Win2003 server on your new box and during the install make it a domain controller as part of the existing domain. This way all of the users, etc withing AD are already there on your new 2003 server. Before you remove the 2000 server from the domain, you would want to transfer the operation master roles to the 2003 server. (you would do this through AD; the roles are: RID master, PDC emulator, Infrastructure master, Domain naming master, Schema master)

    Hi, a while a go I had a similar problem using ADMT to migrate users from one domain to another. Here is an article I used to solve it:;en-us;322970 I also created a secondary lookupzone on both servers AD. As you will see in the article DNS is one of the causes.
