WebException -The decryption operation failed, see inner exception

[jigs]

I'm getting this exception when trying to call external WS that
requires client side certs. It fails sporadically and not always -
Please see the below exception. This is urgent and need some immediate
assistance if possible, thanks.


The underlying connection was closed: An unexpected error occurred on
a receive. ---> System.IO.IOException: The decryption operation
failed, see inner exception. --->
System.ComponentModel.Win32Exception: The certificate chain was issued

Have you considered the possibility that the exception is telling you the
truth?

Do you have more than one server hosting this web service? Is it possible
that some server involved in determining trust is not always available?

Yes. I've checked on all servers hosting this WS. All servers have
accurate certs installed in appropriate stores.

FYI - My WS is a client-side WS and tries to initiate a call to
another WS on the vendor's end.
