Hi,

Good day. My name is Amir. I really need any s from you guys on this.
Two of our client’s DNS servers which are in Win2K3 been installed with ISC
BIND version 9.3.1 and since then CPU usage of both servers’ hits nearly 99%
and drops back to 0% intermittently . I figured out that a process called
“named.exe� that related to ISC BIND is the reason which contributed most to
the CPU usage. Thus, I downgraded the version to 8.4.4 for one of the server
and as result the symptom got disappeared and I am planning to downgrade ISC
BIND version for the server as well. The question is, by downgrading the ISC
BIND version will this give any harm to server’s performance or something?
And what are the advantages to have latest version of ISC BIND installed? Any
explaination or suggestions are very much appreciated.

Named.exe IS "BIND", the service itself.

This is not a "BIND" newsgroup but I have some (random) thoughts
on running BIND:

BIND 9.x and 8.x are really separate products in many ways and
are NOT sequentially different versions (i.e., 9.x is NOT an upgrade
of 8.x) -- so you have weigh the features you hoped to gain from 9.x
and determine if 8.x can offer those to you.

I have run various versions of BIND 9.x on Win2000 and Win2003 servers
with no problems.

Why are you running BIND when Windows Server has its own
built-in DNS service?

(There are reasons for running BIND but if you don't even know
the feature differences between 8 and 9 it is not very likely that
you really need BIND rather than Windows DNS.)

Since Windows Server comes with MS DNS I would wonder why anyone would
install BIND for DNS in the first place. I would suggest you post in one of
the BIND groups.

Hello Herb,

Thanks very much for the reply. Let me brief the situation. These two DNS
servers are being setup after AD migration activities has been done as
replacing the old WINS servers. All the migration and BIND installation are
done by other person/group. As I am doing monitoring on these servers I
figured the symptom caused by ISC BIND.

May I know what is exact version of your BIND running on your Win2K3? and I
believe you have same "named.exe" process running in the task manager and How
much CPU usage that particular process takes on yours?

Thanks again Herb.

Hi Kevin,

I guess my reply to Herb expains the reason why. Thanks for your suggestion
anyway.

I am not at the server location right now, but have run various
versions up to the current one over the last 4-5 years on both
Win2000 and now Win2003.

No, it doesn't "explain" it; you merely said someone else
installed BIND but gave no reasons.

Sometimes BIND can do things that Windows DNS cannot,
but the opposite is also true for Windows DNS can do things
that BIND cannot.

Most of the time for AD networks MS DNS is actually much
better than BIND.

Apparently the policy says to use BIND in DNS server. Tried the latest
version 9.3.3 but it did not make any changes. Stick back to ver 8.4.4 and
the CPU usage looks good so far.

It is STUPID to have that as an AUTOMATIC policy for
Windows AD.

People who make such policies without taking the actual cases
into consideration are unprofessional.
