I haven't seen mention of this in any of the documentation or HOL's but here
it is. Running Win 2k, you have to grant the ASPNET account "Act as part of

I am using separate machines for client and web service. Can get the
x509signing sample to work OK. WSE 2 verifies signature OK.
Accessing web method of my own web service I get the dreaded 'Cannot find
the certificate and private key for decryption' error using the same machines
as the x509 signing sample. Looking at the few differences I have been them

different causing it!
