Thanks Mark,
Two connector configs works.
Any ideas, on why the behavior if different for ISAPI and mod_jk modules?

Two things I would try:
1. Two connectors, one with address='::1' and the other with
address='127.0.0.1', both with port='8014'.
2. Configure the other end explicitly: tell HTTPD and IIS which
address to use, and then configure your AJP Connector to match.
