When : It happens on Friday 5 p.m.• Few IT Staff available• Friday 5 p.m. is a common schedule

because the timeshift between Chicago and Paris.

What : A non-blocking problem• AccessGrid client is working• No Sound• Hum / noises• No video

No video• Quick to decide the issue

Hum noises• Check the plug

No sound• Check the RAT

Validated on Windows XP / with an already tested AG.• Start AG, only once (don’t click too much)• Go into a venue

Change the bridge -> works as the unicast/multicast is getting reinitialized

Turn off AG client / Restart client -> works as the ports may changes (if a Firewall is filtering) as it’s Windows that give the ports

Turn off the computer / Restart (not useful by itself, but helps end-user to decide)

AccessGrid is mature and works fluently• For example : shared browser / shared ppt

you have some local requirements

• It relies on the operating system for opening the internet ports

• It relies on the IT staff for fixing the filtering rules• It relies on the ability of the end-user to fix quick

problem (hum, defective microphone,…)
