Disabling Remote UAC to add Hyper-V servers

[jmertensnetuk]

Hi All,

I have found that on some Hyper-V servers I need to disable Remote UAC to allow me to add the Hyper-V server to the Veeam console. I get an error "Failed to create persistent connection to ADMIN$"

I use the following reg key to do this: https://support.microsoft.com/en-gb/hel ... egistry-se

However in other cases I do not need to do this registry change to add a Hyper-V server and was wondering why that is.

Ideally I do not want to disable Remote UAC with this registry change and want to find the proper solution to this issue.

Hi Jonathan,

Do you use a local admin account to do this or a domain user added to the local administrator group? Additionally, what is the version of your Windows Server when this does not happen?

Thanks!

Hello Vitaliy,

A mix of 3

1. The local administrator account "Administrator"
2. A different local account added to the "Administrators" group of the Hyper-V
3. A Domain user account added to the "Administrators" group of the Hyper-V

The issue seems to occur with the accounts in 2. and 3. more often.

Ok, that's what I've thought. To resolve this you should be using a local admin account, as this one bypasses the UAC restrictions. See this similar topic for more info. Hope this helps!

For most environments, it makes sense to disable UAC on servers. https://support.microsoft.com/en-us/hel ... ows-server

As long as you are not browsing the internet or doing anything on the server console except legitimate administrative functions, UAC cases more issues than it solves.
