Exchange 2003 web access is very slow

I have Dell poweredge 2800 with dual processor 3Ghz that is running win server 2003 and exchange 2003 I configured certificat services to grant IIS default website certificat for secure connection. I don't know if the certificat is slowing down the system, but the OWA is extremly slow even on my local network.

What could be the problem.

...and it should not slow down a beefy server like that.
One thing to check is to ensure that you are not experiencing network problems, such as NIC flapping (constant autonegotiating).  Update the drivers for your system.  The DELL systems had a bear of a time with the Broadcom NICs.

how muc memory to you have on the boxes?

Have you done any perfmon counters on the processor? Mem ? etc..... Are you using anything like nic teaming and non out the box configuration? how many users connect concurrently to this box?

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

The certificate service will be slowing things down, especially if you are outside the network.

Certificates work on a trust basis, and when your browser connects to an SSL site it looks at its built in list to see if the that certificate is issued by a company that it trusts. If it doesn't then it goes looking for more information to ensure that the certificate is valid. It is during this "hunt" things can slow down.

If this is to be a production implementation then you should purchase a certificate. A StarterSSL from RapidSSL will be fine - cheap and does the job.

Yes but if he setup a cert server on his local network and his access is slow locally then there might be another problem.

you can use perfmom to check performance

A certificate should cause no more than 35% overhead, but manages to be around 20%. So, if your server is running at 40% utilization, approximately 8% of that 40% is going to be due to the certificate overhead.

I have reinstalled the whole server. Didn't apply the certificat services yet. Does somebody know if this procedure is correct?

I go to IIS default website security tab and add new certificat. The certificat is applied to the default web. Iget warning that this will be applied also to child objects. I don't know If I should select any. Could somebody clarify

If you are adding the cert at the level then it will apply down --- you can add it just to the /exchange if you want.
