Hi,

I am running an IIS 4.0 web farm. Recently, during certain times of
the day, i would get a "Page could not be displayed" error on some of
my servers. When i tried to connect to a page on the server via port
80, i could retrieve that page with no problem. But when i try to
retrieve the same page via 443, i would get the "timeout" error.

There is no increase in the number of users to my server farm. On
average a server receives 7 hits/sec. The CPU and memory utilisation
on the server looks healthy.

I have no idea where to go from here but I do suspect that the problem
is related to the maximum number of ssl connections my server can
handle.

Does anyone know what is the windows default maximum SSL connections
on a NT4.0 server(sp6a)? Is there a parameter in the registry to
customise the maximum number SSL connections my server would allow?

I have tried enabling SSL caching @
HKLM\System\CurrentControlSet\
Control\SecurityProviders\SCHA
NNEL\ServerCacheTime
and HKLM\System\CurrentControlSet\
Control\SecurityProviders\SCHA
NNEL\ClientCacheTime
to be 120,000ms but that doesnt help either.

Any comments is greatly appreciated. Thanks in advance.

Jack.
