Hi, I have a protection group of 8 windows machines.  The machines were added to the protection group using their host names.  The machines get their ip from a DHCP server.  I see that one of the machines, originally with ip 192.168.1.151, is not 192.168.1.155 and is not being backed up.  Is there a way to update the protection group for the new ip?  Unfortunately, I cannot revert back to the original ip because that ip is now being used by another machine (that’s not part of the protection group).

Hmm...no way that I’m aware of ​@Hammer . I think the only thing you can do is remove it from the PG, then re-add it, then go into the Backup Job, go to the Computers and probably need to re-add. You of course would have differing Restore Point (Backup) Chains. 

Maybe someone else can chime in with a suggestion I’m overlooking..

Best.

Did you try going through the wizard for that machine to see if there are connection issues?  If you use DNS properly with DHCP then it should update and pick it up.  Might need to remove and add again as Shane said.

Okay, thanks…I did try the rescan and it found the machine, but when I go back to the list of machines in the PG, it still had the old IP.

I am sure support could help with that at this point.  Not sure what else to suggest.

Is your DNS prefix set on the VBR server? I had a similar thing in the past where the rescan had issues when you run a non domain-joined VBR with domain-joined PG objects. Can’t remember the details but worth a shot to set the prefix and try rescanning as Shane suggested.

You don’t use DNS FDQN name?   My VEEAM CE uses my Fortinet DNS Server for all IPv4 and IPv6 addresses of every VM and physical machine to back up.

That’s the correct way (to use a proper DNS sever) but you can either use FQDN or the simple hostname. The difference is that for non domain-joined systems you might struggle resolving the FQDN since default workgroup servers don’t attach the correct suffix by default as long as you don’t set it in the IP settings (advanced section).

Hi ​@Hammer ,

I don't know if you have solved your issue but I thinks was a hostname resolution problem. You wrote VM was added by hostname, but after rescan you can see oldest IP address. Have you verified if there are manual entries on file hosts on VBR server?
