This error will appear intermittently and seemingly for no reason when my
Web service tries to contact another Web service over the Internet using
SSL. I'd say about 80-90% of all the requests work without a problem. The
last 10-20% result in timeouts or this "Could not establish secure channel
for SSL/TLS" message.

I'm sure many of you folks have run into this problem when using .NET Web
services over SSL. I've searched Google for a solution and the only thing I
found was this (URL may wrap):

6164.html

However, I do not believe the actual problem is related to a DLL name (and
no I don't have a DLL called Security.dll).

Can anyone help with this problem? My company is losing transactions and
money because of this error and help is greatly appreciated.
