Hello, I want to know what is the recommended ping latency between clients towards domain controllers over VSAT. I aslo request you to share any technet article if available. Thanks Sunny

Hello, we sometimes use SATcom connections with 2Megabit lines and the ping is roundabout 500 ms, if this is the question you have. Please keep in mind that this has nothing to do with the used OS versions as the network is here the reason for ping times and speed etc.Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hello, Our moto is to reduce the network traffic between DC and clients.The ping latency from one of the client towards DC looks as below.

Does this indicates that there is a huge network traffic between client towards DC.What can be done to reduce this traffic. Thanks Sunny

Hi Sunny, If the bandwidth speed between clients to DC is too low, it can cause some connectivity issue for DC to control the clients, such as apply GPO etc. Please check the following thread which may help you to deploy the connection between clients and DCs.
