NT vs. Unix DNS

[Stephens, Bill]

	Sure, the difference is simple.  With BIND DNS, you have the source
code, you can keep your DNS up to date, it is "the standard".  Or, you can
accept stuff like this as normal business (pay close attention to their
standard "workaround"):

	DNS Service Memory Leak 

	
----------------------------------------------------------------------------
----
	The information in this article applies to:

	Microsoft Windows 2000 Server 
	Microsoft Windows 2000 Advanced Server

	
----------------------------------------------------------------------------
----


	SYMPTOMS
	The amount of memory being used by Dns.exe may continually grow and
may not plateau, or memory may not be returned to the system over time. The
rate of growth of the memory leak depends on the number of queries the
server receives per hour. 



	RESOLUTION
	A supported fix that corrects this problem is now available from
Microsoft, but it has not been fully regression tested and should be applied
only to systems experiencing this specific problem. If you are not severely
affected by this specific problem, Microsoft recommends that you wait for
the next Windows 2000 service pack that contains this fix.

	To resolve this problem immediately, contact Microsoft Product
Support Services to obtain the fix. For a complete list of Microsoft Product
Support Services phone numbers and information on support costs, please go

	WORKAROUND
	To avoid this problem, restart the server on a regular basis. 



	STATUS
	Microsoft has confirmed this to be a problem in the Microsoft
products listed at the beginning of this article.



	MORE INFORMATION
	Use the following method to discover whether the service has this
problem on a specific server: 

	Start the Performance snap-in.


	Log the following counters:


	Process--DNS
	Page file bytes
	Working set bytes 
	The period necessary to see the growth depends on how many queries
the server receives per hour. Logging for a week on any server should show
whether there is a steady growth in the amount of resources being used by
the service.

	Subject:	NT vs. Unix DNS

	Hi all.

	The web design company I work at currently runs Unix DNS and we run
NT for
	just about everything else.
	They would like to convert to NT DNS.  I know of many companies that
are in
	a similar situation where everything is on NT but DNS is on Unix.
I've
	tried to research this on the web and have found very little info.
Are
	there some major advantages of UNIX DNS?

	Thanks for your time,
	-Ryan
