Re: adprep /forestprep failure

Nothing special that I know of. When I run the Active Directory Schema
option in mmc on that server (spserver01), the Operations Master for the
Schema FSMO holder shows spserver01.season.com. When I run the AD Domains
and Trust and look at Operations Master for the Domain Naming FSMO it shows
the same. Likewise, the same server shows up in RID, PDC and Infrastructure
roles. So I don't know why the KnowsOfRoleHolders shows this server as the
Schema Owner, but it is marked deleted.

I don't know if it would work to reconnect the other W2k SP 4 server,
promote it to be a DC, transfer the Schema master role to it, and then try to
transfer it back to the original spserver01 to try to reset things.
Hopefully, there is an easier way to clean it up without using another DC,
but I'll do it if that is the only way.

I am trying to add a Windows 2003 Server R2 as a domain controller to a
domain (season.com) with a Windows 2000 Server SP 4 DC (Server name
SPSERVER01). I have successfully added the Win 2003 server as a member
server in the domain, but when I try running adprep /forestprep from Win
2003
server CD 2 ( in \CMPNENTS\R2\ADPREP) on the Win 2000 DC, I get the error
message:

Adprep was unable to extend the schema.
[Status/Consequence]
The schema master did not complete a replication cycle after the last
reboot. The schema master must complete at least one replication cycle
before
the schema can be extended.
[User Action]
Verify that the schema master is connected to the network and can
communicate with other domain controllers. Use the Sites and Services
snap-in to replicate between the schema operations master and at least one
replication partner. After replication has succeeded, run adprep again.

I get this error whether I run adprep from CD 1 or CD 2.

When I run REPADMIN /SHOWREPS SPSERVER01 I get this response:

Default-First-Site-Name\SPSERVER01
DSA Options : IS_GC
objectGuid : e30467f8-01f0-4585-a313-11c255cfca38

When I run DCDIAG /V /C /D /E /s: SPSERVER01 > c:\dcdiag.log, I see a
failure in the KnowsOfRoleHolders section:

The only other failure message here is in the frssysvol section:

Starting test: frssysvol
* The File Replication Service Event log test

3 days ago I saw the following error in the System log:

Source: Schannel Event ID: 36872
No suitable default server credential exists on this system. This will
prevent server applications that expect to make use of the system default
credentials from accepting SSL connections. An example of such an
application
is the directory server. Applications that manage their own credentials,
such
as the internet information server, are not affected by this.

At the same time I saw this error in the Directory Service log: Source:
NTDS LDAP Event ID: 1220
LDAP over SSL will be unavailable at this time because the server was
unable
to obtain a certificate.

This was one day after I reapplied SP 4 to the Win 2000 DC. I have no
idea
if these are related.

Some history that may help in the diagnosis. Before starting this whole
process, the domain functional level was Windows 2000 mixed, even though
we
did not have any NT servers. We raised the functional level to Windows
2000
native. We did have another Windows 2000 Server SP 4 domain controller
(SPSERVER02). It's hardware has been flaky, so after the initial adprep
failure, we ran DCPROMO and it reverted to a member server with no errors.
Then we removed it from the domain and disconnected it.

I suppose the deleted Schema Owner error is a key here, but I don't know
how
to fix that. Any recommendations?

Thanks for any assistance.

Brett
