On the SBS server we need to open port 2967. If I type telnet localhost 2967 at the command prompt I get the error message "connecting to localhost...Could not open connection to the host, on port 2967: Connect failed.

Where on SBS 2003 do you configure ports. An application we have requires that that port be open on both the server and the client. We do not have any software firewalls.

Hi gardnerbartlett,

An application residing on the server itselfs opens a port. Not the server by itself.
Is the applicaiton installed on the sbs server?

Then do a telnet -ab to see whether the application has opened port 2967 for you.

Cheers!

The application is symantec corporate antivirus version 10.1 and it is installed on the sbs server.

telnet -ab give me the same prompt as if I had typed telnet /?.
Is there something else I have to add to the command?

netstat -ab on my xp box gives me a list of ports established or listening.
when I type the same command on the server i get the same message as if I had typed netstat /?. I've checked the syntax and I'm typing them both the same way.
maybe something is stuck in memory. I retype that command after rebooting later this evening.

In sbs, unless you have a third pary firewall, there is no firewall between the server and clients, just NAT, between the NIC that points to the WAN.

We do not have NAT setup. There is only one NIC used. If ports are not closed by default by sbs 2003 and are not opened by the OS but by a progam I need to find out what program may be closing that port. After rebooting I'll se if netstat -ab works.

In that case the windows firewall would be working on that network connection.

My previous example was only applicable for a SBS server with 2 NIC's

Symantec Antivirus DOES use port 2967, but you can't telnet to that port, as there is no protocol established for it.  What is the problem you are having with Symantec?  Because as stated already, it should open that port itself without any need for you to do any further configuration.
