Q. How can I change the port that the BranchCache retrieval protocol uses?

A. The default HTTP port (80) can be changed by adding the value ConnectPort to the registry key HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionPeerDistDownloadManagerPeersConnection. This registry key needs to be added on the hosted cache server and all clients. Once you make the change, open an elevated command prompt and run the commands

netsh branchcache set service hostedserver
net stop peerdistsvc
net start peerdistsvc

For the clients to detect the new port, you need to run the following commands on each client:

netsh branchcache set service hostedclient location=
net stop peerdistsvc
net start peerdistsvc
