Hi Jovert Lumbao,

Do you really mean Protection Domain (Nutanix) or Protection Groups (for Veeam Agents)?

Based on the error message I would rather say you mean Protection Groups and probably want to install a Veeam Agent on a system. Is that correct?

Best regards, Thomas
 

yes correct. installing windows agent.

OK, it's a bit difficult to say what the problem might be. Here are a few questions or things I would check:

• What kind of system do you want to install the agent on? Physical server (model?) or virtual machine
• Which Windows version? All current Windows updates installed?
• Is the agent already installed on the system? Or was it installed before?
• Are there duplicate machine IDs (clones) in your environment?
• Are there duplicate IP/names?
• Does the IP reverse lookup find the correct DNS name? If you ping the DNS name, do I get the correct IP address? 
• Is the date and time correct? On the VBR server and Windows client/server

One last thing, can you add another Windows server to the Protection Group and test whether you get the same error message?
