I was trying to install SCOM 2012 R2 agent from the console on a couple of our remote DR servers, However we received the following error message every time we tried the install. "The operations manager server cannot process the install/uninstall request for computer. Failure of operating system version verification." As checked RDP and Ping worked fine, There was no firewall issue as it was disabled. Permissions for Agent account were correct. However when we tried to access the \\server\C$ it failed. It turned out WAN optimization software was blocking CIFS access As soon as we made changes to allow CIFS access , SCOM agent installation worked fine. Hope this helps.
