I have implemented an Outlook Web Access Server on the DMZ (third firewall nic)of my network. I opened three netbios ports (137udp, 138udp, 139tcp) on my raptor6.0 firewall (Unix)to the PDC as well as three ports for exchange (exchangeDS, exchangeIS, and endpoint mapper port) and set up secure channels to the Exchange 5.5 Mail Server as well as the PDC. I still can’t get authentication to work through OWA. The OWA is set up on NT4.0 Server on a different subnet using an LMhosts file for WINS resolution to the PDC and Exchange boxes. When the OWA Server tries to authenticate a user, I see traffic (at the firewall)only broadcast the request—but get no responses from the PDC??? Any Suggestions?
