    Thanks for responding back...
    I verified that the Web Service is using SSL version 3 Certificates.
    Unfortunately, I can't get any details on their server envirnoment due to
    security reasons. Is there any way to extract more information on why I'm
    getting this error on the client side? The web service call returns the
    following status message:

    Status: SecureChannelFailure

    Also, I enabled detailed logging of the SChannel. The event log entries
    suggest that the SSL Session between the client and the server was
    successful...

    Event Type: Information
    Event Source: Schannel
    Event Category: None
    Event ID: 36880
    Date: 8/30/2004
    Time: 5:44:25 PM
    User: N/A
    Description:
    An SSL client handshake completed successfully. The negotiated cryptographic
    parameters are as follows.

       Protocol: SSL 3.0
       Cipher: RC4
       Cipher strength: 128
       MAC: MD5
       Exchange: RSA
       Exchange strength: 1024

    Any other suggestions?
