Interesting.

Very few members of this list have Ex on DC's for the already over discussed
reasons.  We may be seeing the downside of having such.  Like you say, you
can live with it but it does bug a little.

Your hardware looks fine (well comparing it to mine anyway!) - the box I
already have built and in the rack is a Compaq DL380 with 4 x 18.2Gb 10K2
RAID5 and 2 x 18Gb 10K2 Mirrored, 512Mb memory and dual 1Gb PIII's.  Teaming
NIC's and a 5200 RAID controller finish it off.  I need to set aside some of
the christmas holiday to do the transfer.  I've discounted any bottlenecks
in the LAN as I have just replaced all old hubs and switches with Cisco
3500XL 10/100 switches on GB fibre backbones so it must be the combo of DC
and Exchange that is choking it.

If I get any ideas I'll let you know.  If anyone else has, well.... I think
we'll soon find out....

Regards

PBB

Yes my box is a BDC - Compaq Proliant 1850R - and yes I inherited it as well
so I did not have a choice in the matter.  We are waiting for next years
budget but it looks like we will have to live with this machine for at least
another year.  That is a very interesting thought - there is a 3rd party
utility available called DC-Promo that can turn a domain controller into a
standalone server.  

Thanks
Shawn

Ironically I get pretty much the same as you, bad slowdown at peak times.
Now, my exchange box is a BDC which I know is against the rules but I
inherited it from old and do not have the resource (read time) to migrate
until the new year.  Is yours a DC? - If so this may be the pattern.  FYI,
this box is a Dell 2400 single PIII 500, 3 x 9.1Gb RAID5 and 256Mb memory
(5.5sp4) but only ~150 users in this particular site.

Subject: Exchange Server - Outlook Client Slowdown


I am hoping someone out there is having some of the same issues as we are
having and have come up with some solutions.  Any suggestions would be very
much appreciated.

Our current setup is;

- Single Server Exchange Server Enterprise 5.5 Sp4 running OWA
- Compaq Server Dual PII 450 Xeon Processors
- 5 hard drives - 3 10,000rpm 36.4 GB drives in RAID 5 (Databases)
                    - 2 10,000rpm 9.1 GB drives in RAID 1       (Transaction
Logs)
- Server is running at 100mbps full duplex.
- Pub.edb = 150mb
- Priv.edb 18.5 GB (approx 40GB of free space)
- Circular Logging Turned off - Differential Arcserve Backup enabled
- 200 - 230 Users and 300 mailboxes 

Description

For the past couple of weeks we have notice a perceptible slowdown in client
side response times on our exchange server.  The slowdown mainly happens at
peak times,(9-10am and 2-3pm) however we have noticed it with attachments
and at other times as well.  It sometimes can take 5-8 seconds to open an
e-mail with an attachment where we have been getting immediate response
before.  For scrolling through messages in Outlook we have also noticed a
slow down. Also - when copying an attachment from an e-mail to your local
machine,(right click and copy, then paste to desktop) this response time has
decrease dramatically.  Although these slowdowns do not stop us from working
on a daily basis we would like to get on top of this issue and do what we
need to do to keep our Exchange server speedy. 

Any ideas or recommendations are appreciated.

Regards,
