Event ID 5781 - Netlogon Warning

[Jose Vieira]

If you are in the following conditions:

- Running win2000 + SP4
- Active Directory Integrated and DNS dynamic updates
- Netlogon Warning event ID 5781 on DC's
- Clients do not update in the DNS
- Single name for the domain name
- ...

Probably your problem will be resolved reading the article
described in:

It worked for me.

Many thanks also to Kevin Goodknecht Sr. [MVP] for their
hint.

Not a problem at all I'm glad to help. Actually I found that by coincedence,
that article was originally for XP Pro clients and when I went to review the
article a few days ago, I noticed it now includes Win2k SP4. Since the
release of SP4 the 5781 events have been posted daily.

Strange that article applies to this, now that it was updated. If you ask
me, it merits a separate article.

One other guy deleted his "disableDnsUpdate" key in the reg under TCP/IP
service and it worked.

Go figure...

In Jared Cronin <[email protected]> posted their concerns
Then Kevin made his reply below:
Hi Jarod,
Hopefuly the email mixup was an accident, What is your actual domain name in
ADUC?
What is the primary DNS suffix?

This may just be a disjointed name space which most of the time can be
fixed.

If this is an actual single label domain name, this is going to be just a
start of the problems you are going to have. Legal DNS names need a domain
name follow by a top level domain ie domain.TLD After SP4 Win2k won't
register in the TLD that is the reason for the error. To fix it right you
would need to set up a new DC with the correct domain name format.
