Error 5719 NETLOGON - default domain

Hi all

Repost in correct category!

Running an NT4 server with two Windows 98 clients that log into the domain in the usual way and process login scripts, and one XP Home machine that has a compatible IP address and accesses network shares using the NET USE command.

All is seemingly fine except for random server reboots, about every 36-48 hours - apparently at night but with no discernable trigger.

I've got a strange error in event viewer on the server, that appears every 15 minutes ALL THE TIME.

User: N/A
Event ID: 5719
Source: NETLOGON
Type:  ERROR
Category: None
Computer: (the correct name of the server)

No Windows NT domain controller is available for domain DOMAIN.  (This event is expected and can be ignored when booting with the 'No Net' hardware profile.)  The following error occurred: There are currently no logon servers available to service the logon request.

Note that the error actually contains the domain DOMAIN - and this is not the name of our domain!

All I can think is that a machine with a default setting is doing something I don't know about.  I've physically unplugged the XP Home machine - no change.  I checked for RestrictAnonymous in registry as per a similar post but it's not there.  I think the key must be this default DOMAIN but I can't find any references to that in any machines including the server.  PCAnywhere is running for remote support but it always has been.  I notice IIS is running in the task list and I don't know why - but again, I'm not aware of this being installed recently.

Any ideas please?

Thanks

Lots of things can cause this. See the following link for MS Articles:

Thanks - I've had a look - as you say, lots of possibilties.

Any comment on the "domain DOMAIN" bit though - that's what's giving me the biggest confusion!

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this problem, increase the MaxDgramBuffering value from 128 KB to 256 KB:
Start Registry Editor (Regedt32.exe).
Locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters

On the Edit menu, click Add Value, and then add the following information:
Value Name: MaxDgramBuffering
Data Type: REG_DWORD
Value: 0x40000

Quit Registry Editor.
Restart the Netlogon service (you may have to restart the computer).
NOTE: If you are using Regedit instead of Regedt32 to modify the registry, either
right-click Parameters, click New, and then click REG_DWORD -or-

click New on the Edit menu, and then click REG_DWORD
and then add the new registry key information.

I saw that solution when I was searching but it seems to relate to 2000 Server and this is NT4.

Same solution, do you think?

I would say so, besides if this key is not implemented in NT4 then it would simply have no effect, doesn't hurt to try.

I have had a similar problem in the past.  You can use a program called NetDom (from the NT Resource Kit CD) to check and reset the SID between the server and the workstations.  Also, make sure all the computers' clocks are set to within a couple of minutes of the server (check the date and the time zone as well) and then remove them from the domain and re-add them.

OK, thanks.

I'm away from the location for a bit so if no-one minds I'll post back with what I tried in a few weeks...

Awarded points as fairly as possible.  In the end we replaced the server because it was having other problems which may or may not have been connected.

When I have time I'll look over the old one again and try the suggestions and post back if there are any results.

Thanks all
