When Deploying the JAMS Agent to a Windows machine, the DeployAgent Job may fail with the error:
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
This is usually the result of the firewall blocking access to remote management. On the target machine, open a Command prompt as an Administrator and execute:
netsh firewall set service RemoteAdmin
Note: that if you have a 3rd party firewall, the procedure to allow remote administration will be different.
