Exchange IIS issue


I have configured SBS 2008 and configured exchange. However users connected via https remotely have the issue that it prompts them for their credentials and won't let them login. I found if I restart the IIS web applications it fixes the issue, so I think the problem is IIS. This then re-occurs 24 hours later.

What could be causing this? Where should I look?

Do you have a trusted SSL certificate on the server?
Is Exchange 2007 on to Service Pack 3? The Exchange service packs do NOT come down automatically, you have to download and install.

As this is SBS 2008, recreating web sites and directories is not a good idea as it will break a lot of other functionality. SBS 2008 makes extensive changes to the configuration of IIS.

Presuming the server is fully up to date, I would start by running the SBS BPA, you can find links to that here: 

Correct any problems it flags.
The fix my network wizard inside the SBS management console can also resolve a lot of problems.

Please take a look at the Windows Application Log (run eventvwr). It should give you further details. Search for Warnings and/or Errors events.

As David, I would check if the SERVER is fully patched. Does the Microsoft Update (not only Windows Update) list any available patches?
If the SERVER is fully patched, you might consider recreating a new Exchange Web Site. You might even have 2 at the same time. So, leave the semi-working Web Site as it is and create a new one. This is what I would do.
Please let us know.

Not sure about Service Packs for Exchange. I will have a look and get back to you. Thanks guys.

So I don't have the service pack, however I have downloaded it and I cannot work out how to install it. Is there some trick to it? (sorry I am a novice to Exchange).

Download, double click to extract, then run setup.exe and follow the prompts.
Nothing very complex.

You may have to stop and disable the Windows SBS Manager service prior to the install as it can bring up an error on the initial readiness checks saying that the Data Collector has open files.

Restart the service after the install.
