Hi
good day
this is my first post on Veeam communities
please I need help with adding HyperV hosts to my Veeam infrastructure
I did an upgrade to Veeam 12 about a month ago. I realized that my HyperV hosts were offline. Of four, two are running Windows Server 2022.
i saw some things about DCOM Hardening which I don’t want to accept (yet)
can anyone help me with measures to resolve this problem?

Hi
Just following up again to see if you were able to add your Host to Veeam?

Hi
Were you able to resolve this? Curious how you did if so.

Once, i was the same trouble and open one ticket at the Veeam. We discovery one att at windows, i dont remember the KB.
Did you att your Veeam or OS from hyper-v server ?
You can check UAC account permissions too.
In my case, was this KB, at the hyper-v server:
Perhaps help you !

Are you seeing any of the events in this article in your event logs.
Are you adding it by ip or host name as DNS will need time to update
IP address, not FQDN

If you want to use DNS run - ipconfig /flushdns to refresh it then ping the hostname to see if it resolves the new IP or not.

Hi
I did an NSLOOKUP
And found another appliance sharing that IP address.
I changed the IP
Error was still persistent.

The logs show references to a cluster …. was the name / ip previously assigned to a hyper-v cluster?
If you do nslookup on the host IP does it just return a single host name? or nslookup on the Name even :)
When you said the firewall is disabled was that on the VBR server or the host?
Are you adding the hyper-V hosts standalone or as a cluster?

Hi
I have done everything here, and the error is still the same.
I also ensure the UAC from the Control panel was disabled
Error is the same.
I have tried both Veeam 11 and 12.
Same error.
The Veeam 12 is an upgrade of the Veeam 11.
All not working.
LocalAccountTokenFilterPolicy registry key and set it to 1 to disable remote UAC restrictions.
Same thing.
i found some logs in the Backup folder.
The highligted parts seemed very noteworthy:

Additionally, make sure you have File and Print Sharing service enabled, as noted by prerequisites noted in the Guide.

The irony of this is,
I tested another backup software [I will keep the name]
I was able to discover the hosts and the VMs.
Same procedure.
‘No tweaking or reconfiguration.
Honestly, are we sure this is not really about Veeam and HyperV hosts?
I was able to access the admin shares and the c shares with the same credentials giving me errors here.
The first screenshot was included to show that the username format was HOST\User
the password used was also checked [I can’t put that out here]
The windows firewall is also disabled:

Like the message states did you check permissions and expired password? You need to use a local Administrator account on the host to connect.
Also check the Veeam logs here - C:\ProgramData\Veeam -- see if there is any information there.
Also ensure Firewall ports are open and not blocking.
So what logs exactly am I examining here?
Check the Backup folder to see if there is anything of relevance and also ensure the credentials as per Shane’s post for the format.

What’s the format of the local credentials you’re using? It should be in the format of HOSTNAME\user (not .\user), or for a domain account DOMAIN\user.

Can you get to the Admin$ share on the hyper-V host? \\192.168.1.126\Admin$ Also can you ping the host?
I suspect the windows firewall is enabled and you’ll need to disable it 1st if you’ve not allowed the ports. Veeam will create the firewall rules allowing you to re-enable the firewall after readding it back in.

Keep us posted on the result when you’re able to test this out.

What you disabled was the UAC within control panel probably. What I’m suggesting you disable is REMOTE UAC from within the Windows Registry. No...2022 doesn’t matter. This is a known “issue” (security enhancement) for Windows devices for a while now.
