how to migrate from windows 2008 to windows 2003

Hi all,

I have two domains windows 2008 and windows 2003. I am looking to migrate windows 2008 users to windows 2003 using ADMT 3.1, looks like it would do it but is failing with the following errors in the ADMT log. first of all is this a possibility?

2010-09-17 16:52:45 ERR2:7697 Unable to get global catalog server name for forest 'target.local'.  The specified domain either does not exist or could not be contacted.
2010-09-17 16:52:45 ERR3:7585 The account replicator is unable to continue.   The specified domain either does not exist or could not be contacted.

Thank you in Advance

Have you tried version 3.2?

And run the program from the 2008 server and not from the 2003 server? ( Not sure where you start your program now )

unfortunately, the folks who installed win 2k8 have installed it in 32 bit os, so I cannot use admt 3.2

Well you could always add a Windows 2008 x64 machine to your Windows 2008 domain, promote it to a domain controller, and then try ADMT 3.2. You could do it in a VM.

unfortunately ours is windows 2003 domain. I am afraid if it would mess up the schema if I brought in a 2008 AD server.

I was thinking to introduce the 2008 domain controller in the existing 2008 domain.

Actually I just got the problem taken care.

1. the admin in the win2k8 domain had a firewall blocking most of the ports, so I asked him to open all communications between the source ( 2008 AD) and target ( 2003 AD). But I still was having the same error.
2. I then installed a older version ADMT 3.0 on 2003 AD server and did the migration. smooth as silk. :)

Thank you one and all.
