Rescan host failed?

[BassTeQ]

Hi,

I've just updated to the community edition and trying to configure a physical machine backup.
In the inventory section, I can see my host listed, however it appears it's having trouble scanning it.
Any ideas?



Thanks

Try to remove and re-add the host.

[BassTeQ]

How do I do that, there's no option to remove the host in the "manually added" section as per my screenshot.
I think it was added when I created a backup plan?

I also have Veeam Windows Agent Free installed on the same pc, not sure if that may be causing any problems?

[DavoudTeimouri]

Right click on the group; 'Manually Added', select 'Properties', 'Computers' and remove it from there.

[BassTeQ]

I've removed the host and added it again, I've completed the credentials test and it passed.


However looking at the logs, it shows "access denied" ?


Any ideas?
Thanks

anyone?

Hello Bass,

Sorry for keeping silence. Any chance this host was managed by another Veeam B&R installation? Thanks!

[BassTeQ]

No problems, I still have veeam backup agent for windows installed on the same host, could that be causing an issue?

[Dima P.]

You mean Veeam Agent for Windows is installed on the Veeam B&R machine? Thanks!

[BassTeQ]

Yes thats right.

As a test, I created a fresh win 10 VM and installed veeam B&R, disabled the firewall.
Created a new protection group, added the IP address of the VM, did a credentials test, completed OK. Attempted a host rescan and it also failed at the same point. I'm not sure of I'm doing something completely wrong or what it is, it's just strange that I've recreated the problem on a clean win 10 install.

I was successful however when I added a windows 7 PC to the protection group, the rescan worked fine, could it be related to windows 10?

Thanks

Hi all,

Looks like I've found the root cause to this problem. I had to disable UAC is the registry and reboot, the host now scans successfully.

Open the registry. Path; "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\policies\system -Name EnableLUA -Value 0"

That worked for me too, thank you @BassTeq.

Hi all,

Important side note. Know that disabling UAC (LUA) is a security risk and I wouldn't recommend doing so unless you are sure that nobody with bad intentions can access your computer.

Gribri,

I am with you on that. Generally we do not recommend to disable any Windows built-in security tools but sometimes it's required to understand the root cause. In this particular case we've discover that UAC is blocking the agent rescan activity and from the admin perspective it's clear that UAC policy requires fine tuning.

If I remember correctly the User Account Control Group Policy and registry key settings this option should help:

User Account Control: Only elevate executables that are signed and validated ValidateAdminCodeSignatures Disabled
