SYMPTOMS
When you configure the TN3270 service in Microsoft Host Integration Server 2004 to support Secure Sockets Layer (SSL) encryption, the TN3270 service may not start. Additionally, event messages that resemble the following may be logged in the Application log:

Event message 1

Source: TN3270 Server

Event ID: 1025

Event Time:

Description: A server certificate was found but was invalid, chain error 0x1000040

Event message 2

Source: TN3270 Server

Event ID: 1024

Event Time:

Description: Server authentication certificate with common name

not found

Event message 3

Source: TN3270 Server

Event ID: 1022

Event Time:

Description: Port 23 rejected - no credentials available

Event message 4

Source: TN3270 Server

Event ID: 1021

Event Time:

Description: No port security records available - no ports configured

Event message 5

Source: TN3270 Server

Event ID: 102

Event Time:

Description: TN3270E Service initialization completed by initialization error.



CAUSE
This problem occurs because the TN3270 service incorrectly calls the CertGetCertificateChain function together with the dwFlags parameter set to CERT_CHAIN_REVOCATION_CHECK_CHAIN. The dwFlags parameter should be set to CERT_CHAIN_REVOCATION_CHECK_CHAIN_EXCLUDE_ROOT instead.
