I have several web sites on my server. One of them redirects to https. Often
all my http sites goes down except https. Restarting IIS fixes problem but I
want to know why and how to resolve this issue.

IIS version?
Sounds like a problem with your websites... because HTTP and HTTPS are
handled by IIS in the same user-mode process, so if you say HTTPS
stays working, it means the problem is with the website(s) and not
IIS's ability to handle HTTP/HTTPS requests.

Thansk David,
I am using IIS 5.0.
If there is a problem with websites, all 6 websites are having same problem
and same time. Also it fixes the problem after IIS reset. Do you think https
redirect has something to do with this?
Appreciate your help.

I don' think HTTPS redirect is involved.
What is the Application Isolation of all the websites. I suspect all
websites which have the same problem at the same time are either all
in Low or Medium Isolation.
If so, this indicates that one (or more) of the websites have
something that crashes IIS, which IISRESET recovers from.
You can check in the Windows Event Log to see if there are any
warnings/errors regarding "IIS Admin Service" or "World Wide Web
Service". If so, you want to try diagnosing with a tool like IIS State
or DebugDiag to trap the crash when it happens so that you can
determine the culprit causing your issue and fix it -- so that you
don't need to IISRESET to recover from the bug in the website.

David,
I checked the Event viwer and I didn't find any error related with IIS
Admin. Only thing I see is the error that Schannel, Event ID 36871 which is
about the SSL Server certificate. Would it something do to with my problem?
Thank you for posting and hope we can get the bottom of this issue.

The SChannel event log entry does suggest that you do not have the
HTTPS site configured with a proper SSL certificate, which may/not be
related to your problem. Your choice as to what you want to fix or not
fix.
