Answer 1

I have solved this problem. Please refer to this thread: http://social.technet.microsoft.com/Forums/forefront/en-US/d2624655-e6ff-4947-b1a8-a2edcffd8a21/denied-connection-netbios-session-protocol#68321990-4ac4-46fa-b7f8-9e0ded3234bb

In detail: I was receiving the following error from ISA when trying to connect from my SBS 2003 Server to my offsite MSSQL Database Provider via SQL Server Management Studio:

Denied Connection
Log type: Firewall service Status: A packet generated on the local host was rejected because its source IP address is assigned to one network adapter and its destination IP address is reachable through another network adapter. Rule: Source: Local Host ( 192.168.1.1:29859) Destination: External (...:139) Protocol: NetBios Session

I have figured this out. I had to add "Local Host" as one of the sources for the ISA Rule that I had initially created to allow SQL Server Management Console connections in the first place. That rule was allowing "Internal" sources but not the Local Host (127.0.01), which is needed for this scenario.
