I have an application which uses ADS and I am attempting to deploy it in a Windows network environment with a rather restrictive firewall. I am having a problem configuring firewall ports appropriately.

ADS lives on \server, and it's listening on port 1234. When \client tries to connect to \server\tables, I get Error 6420 (Discovery process failed). When \client tries to connect to \server:1234\tables, I get error 6097, bad IP address specified in the connection path. \server is pingable from \client, and I can telnet to \server:1234.

If I try to connect from a client machine inside the firewall, either connection path works fine.

It seems there must be something else I need to open in the firewall. Any ideas?

Thanks, Aaron.

ADS lives on \\server, and it's listening on port 1234. When \\client tries to connect to \\server\tables, I get Error 6420 (Discovery process failed).

Edit: I should have specified that the firewall is open to \\server:1234 specifically for TCP traffic. Is UDP involved here in some way?
