OCS 2007 R2 - Live Meeting: Sharing a files fails


When we try to share a file with a person outsite our network, it gives us an error on the computer outsite our network: "Content failed to download due to  a problem with the Conference Center configuration. Contact your administrator"... I'm the f* admin and I have no f* clue :).. On the computer on the inside, it keeps loading the document... I've tried sharing a whiteboard and it works perfectly... So its only the file sharing..

Does anyone know how to solve this?

Nope for a person outside the Domain to Download a File through live meeting you would need Reverse Proxy.

The same goes with address book download.
If you need to download the Address Book from the Commuicator Client from Outside the Domain then you need reverse proxy configured.
Else you would get an error message on the top right hand corner of the Communicator Client.


Do you have Reverse Proxy Configured for OCS on the Firewall? (Like an ISA Server).

Was the file sharing feature from outside working before?
Sum WumAuthor Commented:
We havent got any reverse proxy.

No file-sharing has never worked and the whiteboard didnt work until last week where we made som changes.

The File Sharing externally is possible only if we have Reverse Proxy Configured on your Firewall.

I know best practise is to have a reverse proxy. But shouldn't file sharing work if the whiteboard works?
Sum WumAuthor Commented:
I have just tested all the possibilities in Live Meeting.

I can:
Share a program
Share Your Desktop
Start Remote Desktop Sharing
Poll page
Text page
Web page

I cant:
Upload file
Screen snapshot

Wouldnt it be almost everything that wouldnt work, if it was the reverse proxy that was the problem?
