Troubleshooting or tuning your network for Sametime

In the event that you may need to troubleshoot network issues or tune your network for Sametime, we have provided some resources for you. Especially after an installation or migration, you may find that servers and/or clients are not connecting and, therefore, may need to troubleshoot what may ultimately be a network issue. One tool that is good to have in your administrator's toolkit is the Wireshark Network Analyzer. This allows you to "sniff" network traffic to see what is occurring during a network transmission. Of course, check with your network administrators to see if they permit this type of tool before you start analyzing network traffic.

Sametime Meeting Server audio/video tuning

If you are considering deploying the Sametime Meeting Server with audio and video capabilities, you may need to tune both your Sametime servers and your network to address the bandwidth usage that may occur as meeting room usage increases. Deployment of the Sametime Bandwidth Manager will help you manage your audio and video traffic across the network and track usage; however, there are also some resources for tuning the Sametime servers for this specific need and these are as follows:
