After doing "adprep /forestprep successfully", I go to the Infrastructure
Master (Win2000 SP4) and do
adprep /domainrpep but I keep getting error:
"Adprep was unable to complete because the call back function (null)
failed."

Could you provide us with more details - there should be Status message
or can you check adprep.log which should be in subdirectory of
%systemroot%\system32\debug\adprep\
 
I ran this from the infrastructure master. Netdiag and dcdiag didn't return
any error that I can see.

Adprep checked to verify whether operation

stem,DC=it,DC=mycompany,DC=org has completed.

[Status/Consequence]

The operation GUID already exists so Adprep did not attempt to rerun this
operation but is continuing.



Adprep was about to call the following LDAP API. ldap_search_s(). The base
entry to start the search is
cn=446f24ea-cfd5-4c52-8346-96e170bcb912,cn=Operations,cn=DomainUpdates,cn=Sy
stem,DC=it,DC=mycompany,DC=org.

Domainprep succeed

I was having the same issue in my testing environment and succeeded but don't know what exactly fixed it.

I first tried to create a new user and did a forced replication of my 2 DCs in the test domain.
I had to restore the SYSVOL and NETLOGON shares and copied all the GPs from the prod environment to the test environment.

I tried 4 times without success and the 5th time it went well.

So don't know exactly what fixed that issue.

I've been told by MS (I opened a case) that when you create a test environment without the same Hardware it could be some issues that you will run into.

Good luck.
