DNS Service is Terminating -- Please Help!!

Our Windows 2K network has been up and running and stable for many months,
basically since January 2003. The DNS service has been working error free
and replicating the dynamically registered entries among all 5 global
catalogue servers. Approximately 1 month ago on the PDC I received an error
record in the event log, that the DNS service on the PDC had unexpectedly
terminated. I simply restarted the DNS service and everything continued
working error free. Now, approximately 1 month later, the same error has
occurred again. I simply restarted the service on the 1 server and
everything is fine.

As follows is the error message:

**********************************************
Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7031
Date: 1/17/2004
Time: 4:02:14 AM
User: N/A
Computer: CORPDC01
Description:
The DNS Server service terminated unexpectedly. It has done this 1 time(s).
The following corrective action will be taken in 0 milliseconds: No action.
**********************************************

When I investigate the matter in the Knowledge base, it states that the
problem may occur if a parenthesis appears in a hostname that is contained
in the DNS zone file. It states that a solution is to apply SP4.

The server has SP4 applied and it was applied before this error ever
happened.

I have scanned all of the host records in the zones and I do not see any
parenthesis in any hostnames.

Does anyone have any idea of what else could be wrong? We are using DHCP
and dynamically registered DNS, all Active directory intergrated and
everything has been working perfectly, now this sproradic error has
occurred.


Thanks for your help,

Just a side way suggestion,
In service control manual, for DNS Server, set
On first failure- restart, 2nd failure -restart.
This is not a solution to your problem, however, just occured this, hence
this suggestion.

Are your DNS services internal use only ??
There have been circumstances where dns.exe would cave
without msgs in response to specific query circumstances,
but AFAIK all publicly referenced known conditions are fixed
with SP 4.
If you occassionally profile memory consumption of dns.exe
do you find it grows beyond what can be accounted for by
extent of cache growth ?
 
Ace,

Thanks for replying, but I went to the link you sent and it directed me to
KB article Q813425. I have already found that article and as I wrote below
it is where I got the info of a parenthesis in a hostname causing problems
in pre-SP4 installs. It's really got me stumped right now, because I don't
see any parenthesis anywhere and I'm not having any other abnormal errors or
events logged. We have a very basic network, we're not running IIS and such
because we just need to service printers, control access to storage and
lockdown desktops. Also, at the link you sent, it described a possible
virus infection. We are running realtime on this server Symantec Corp 8.1
and late at night also doing a full scan of the drive, so I feel that we're
not infected.

If you have any more thoughts by all means let me know.

Thanks so much for your help,

Roger,

The DNS service is only used for internal purposes and it's also very
lightly used. We don't have many users, <40. The server does have SP4
installed because I went back to the Control panel just to check.

You wrote about memory consumption, how do I check that. Also, let me say,
we haven't rebooted this server since approximately October, so it's been
running possibly 90 days. Do you think that could be the problem?

Thanks so much for your help, it's really appreciated.

It seems to me that stopping and restarting DNS would
be as effective as rebooting the machine in terms of
giving DNS serivce a fresh start.

You can get a handle on memory use by checking in
Task Manager and selecting to view more than the
columns shown by default (or with system monitor).
The only reasons I asked the two questions are to
assess hostility level of what your DNS is exposed to
and because one of the fixed issues is for a memory
leak that had same behavior - stop without msgs.

Try following Alan's suggestions. Also, I would look for other unusual
characters, such as underscores and spaces (they are illegal DNS characters
also). I would also suspect if your domain name is a single label name.

Ace,

Now what do you mean by this statement: "I would also suspect if your
domain name is a single label name."?

Our domain is of the form: corp.acme.com

Thanks for everything,

Joe

THen it's not a single label name. It's just one possibility I was looking
at.
