We have notice in PAM , if PAM service get stopped then we could not take direct RDP session to any of the agent windows servers though rule for direct RDP is not created yet. How can we overcome from this issue? because if anyhow PAM server get down, then normal mstsc / rdp could not be done till the PAM server get started.

So, We want to create backup pam server, so, if one PAM failed then other will start automatically. Noticed that , in hosts ,in admin console there is option "add domain" . Is that related for configuring backup pam ? Can anyone explain the steps please ?

Thank you.
