Exchange Server on DC |
|
|
I am running a new Exchange Server 2003 on a new Windows Server 2003 domain
controller. (Small organization; no option to separate the functions at
this time.)
I ran the EXBPA today.
Two of the warnings complain about a missing /3GB switch in boot.ini with
over 1GB of memory. The documentation for one of the warnings says this
setting will improve the performance of Active Directory. The documentation
for the other warning says this setting will imporve the performance of
Exchange. Well, that seems a no brainer.
But then there is a warning about have Exhange on a DC. This configuration
is supported, but not recommended. The documentation for the warning states
that with this configuration, "You should not take advantage of the /3GB
startup switch in Windows because it could cause Exchange Server to consume
all memory, thus starving Active Directory."
So now I question all of the settings tweaks that ExBPA and other sources
are recommending.
Is there a resource which specifically discusses this configuration and what
does and does not need to be done differently?
Thanks,
Tim C

Hi Tim,
If a server is dedicated to Exchange or dedicated to AD, and it meets the
requirements for using /3GB (e.g., supported OS and 1 GB or more of physical
memory) then you would normally want to use the /3GB switch. But, if the
server is running both Exchange and AD, then you do not want to use the /3GB
switch, as it will cause Exchange to choke out AD.
Does this help clarify things for you?

I guess what I am asking is if there are any other recommended settings that
are not recommended when Exchange is on a DC. (As well as complaining about
that particular caveat not being mentioned in either of the articles which
separately recommend /3GB for DC's and Exchange servers.)

Re: Exchange Server on DC |

We have a list of issues when running Exchange on a DC in one of the ExBPA
articles -
http://www.microsoft.com/technet/prodtechnol/Exchange/ExBPA/92e23d0b-d52c-466e-b885-0e7e812efd56.mspx.
The /3GB switch is the only setting I am aware of that you should avoid when
running Exchange on a DC. I've logged a bug to see if we can change the
rule that checks to see if /3GB should be used to specifically check to see
if Exchange is on a DC before making this recommendation.
Post back here if you have any questions about this.

Hi, Scott,
I want to jump in here and encourage your group to continue the work on
rules for the SMB and find a way to run the tool only for the SMB.
This market is growing and our company, like many large IT/hardware
companies, are pushing into it expecting thousands of Exchange and AD
installations in configurations like Tim describes. They all want a larger
share of this market and you guys need to do everything you can to reduct
support calls where sufficient knowledge to manage Exchange and AD will not
exist and cannot be budgeted.
Our company wants to use and encourage use of the exchBPA tool as this
massive installation takes place.
Please pass these comments on to Paul.
Thanks and keep up the great work!

I also have the same setup as Tim and have removed the /3GB but I realize
that I have the /USERVA=3030 switch and am not certain of whether this is
directly linked to the /3GB switch or if it should remain in my boot.ini or
not. Thanks in advance. |

Hi,
You should only use the /USERVA=3030 on mailbox and PF servers that are also
using the /3GB switch. If you removed the /3GB switch from your Exchange
Server's boot.ini file, you should also remove the /USERVA switch (and
reboot).
Hope this helps.
