Configure ISA Server 2004 to Allow Exchange and Windows Logon RPC Traffic

Hi All,

I am currently having a problem getting my Exchange 2003 Front End server to start its services when separated from my corporate network by an ISA 2004 server. The error is always RPC server unavailable. I have enabled the RPC protocol (all interfaces), LDAP, Kerberos, CIFS services. I know it is an ISA config issue since I have tried to bypass the ISA and start the services. Everything worked normally when the bypass was in effect. If anyone has any idea as to what I need to do it would be greatly appreciated if they shared it with me.

Thank you.

To start with,
Open the ISA GUI.

Click on monitoring - logging.
Click on start query
watch the logs when you try and start the services.

Any deny messages seen?

Thank you for pointing me in the right direction. I am new to ISA, I didn't know it had the ability to display realtime packet filtering decisions. As it turns out. The problem was the fact that my Enterprise Policy was denying RPC traffic despite the fact that there was an array rule which allowed it. I created an enterprise level rule to allow RPC traffic to and from specific servers. Everything works now.
