We are using ISA 2004. The workstation is XP SP2 with firewall client installed.
We are trying to video conference to the outside world using the Logitech vid software.
When trying to make a connection, ISA has the following error:

Log type: Firewall service
Status: The object cannot be created because an object with the same name already exists.
Rule: Internet Access Groups
Source: Internal ( x.x.x.x:2599)
Destination: External ( 66.151.151.20:5062)
Protocol: Unidentified IP Traffic (UDP:5062)
User: somedomain\someuser
Additional information
Number of bytes sent: 0 Number of bytes received: 0
Processing time: 431250ms Original Client IP: x.x.x.x
Client agent: vid.exe:3:5.1

I don't understand what "The object cannot be created because an object with the same name already exists" means and what the object could possibly be. What possible "object" could ISA be complaining about and/or what could possibly be the problem? Thanks for any help.

Have you created the correct outbound access rules? Have you server published the camera's IP addrress?

Thanks for inquiring Steve.
Yes oubound access rule has been created. Right now it just states to allow all outbound protocols for authenticated users. Very simple.

As for publishing the camera's IP, no. That's not how we want to use it. The camera is attached to a Windows XP computer and is to be used to make only out going calls from it for video conferencing with people who allow incoming calls using the "Logitech vid" software, but this workstation and camera will not be recieving any calls and will not be published.

When we try to call someone who is also using the Logitech vid software, that's when ISA is coming up with the error message stated previously. Thanks for any help.

Dear dear dear.....If the corresponding party is to see your user then you will have to publish the camera..you can make it granular by only allowing the IP address of the 3rd party to use it. Also, all out does "NOT" mean all out......

You need to create proper access rules for the protocols & ports that the camera uses.

Steve, I really appreciate your efforts in this problem. Having a conversation such as this can be rather difficult. It's hard to get all information in the first post. It makes it to lengthy where things get missed or misunderstood or no one replys and so I find that if you start slow and build on information exchange, it's sometimes better. Sorry for going on but the next piece of this is:

I understand what you are saying about creating rules and publishing the camera, however, this ISA server is only being used as a Proxy and caching server (single NIC). Not as a firewall. It sits behind a Cisco firewall and only does proxy services. I can configure the Cisco firewall for the camera, and that works. I would rather that the video conference work through ISA so that I don't have to create extra rules in the Cisco.

The rule in the Cisco for the ISA server pretty much lets it do anything that it needs to (according to our Cisco expert, which I am not). According to our Cisco expert, anything initiated by the proxy can come in. Anything that is not intiated by the proxy can not come in, unless specific rules are create, which I'm hoping to avoid.

The problem is that when trying to video conference, it does not get past the proxy. The proxy keeps coming up with "The object cannot be created because an object with the same name already exists". Which I have no idea what the "object" could be or what the object with the same name is. In this setup, I don't think that publishing the camera through ISA is going to work. Using the Logitech software, two people meet on their site and initiate a video link between them. Which is a little different than connecting to each other directly. Thanks for any insite on this problem or any other suggestions that you might have.

Mike
