Failed Unable to install backup agent: failed to connect to [computer name] Error: Access is denied.

What format of the credentials are you using?  For a workgroup you need - hostname\username and if domain then - domain\username.

If you search the community there are many topics on this subject with different answers and information.

Thank you for the response.

I have computer name as my hostname (double checked by command line winhost) and user as hostname\user.  I even added the user through the ‘Check Name’ dialog box to ensure it’s in there correctly.  I have tried searching and will continue to but I haven’t been able to find a solution yet.  

You may need to contact support and open a ticket.  Also try searching the forums as well - HTTPS:\\forums.veeam.com

Hi @heyr8kb -

Do you have Windows UAC enabled? Try disabling that if you do.

Also, I’m also seeing a bit of discrepancy between what you’re attempting to connect to manually versus what the error says. I’m seeing “ipredacted” and “computername”. How do you have things configured?...via IP or hostname? This I believe is Veeam Windows Agent correct? And, it sounds like you have everything connected to just this 1 computer...your local computer, right? As such, be consistent and use just 1 naming convention → IP or hostname. I wonder if you have your hosts file configured with your IP address? Go to:
C:\Windows\System32\Drivers\etc\hosts and put in a line for your local computer’s IP and map it to your computer’s hostname. See if that works for you.

Try those things and let us know.

Hi thank you for the response.

Some more details: I am on Win11 running Veeam Backup and Replication Console

Job looks like this:

Computer Backup

Workstation

Individual Computer

Under ‘Computers’ I added a computer with my Hostname i.e. MyComputerName - I actually have never typed an IP in at all in my setup.

I then added my only local account which is administrator  as user name MyComputerName\UserName

I went into my user and set UAC to ‘never notify’ - is that turning it off?

When I try and run the job it attempts to rescan and I get the error ofFailed Unable to install backup agent: failed to connect to MyComputerName Error: Access is denied. Failed to connect to share '\\myipaddress\ADMIN$'. 

If I try and copy / paste this \\myipaddress\ADMIN$ into a startmenu:run command it opens the folder successfully

One strange thing I noticed is that myipaddress listed is the one from my vethernet as opposed to my regular 10.0.x.x from my wifi (I have hyper-v enabled) - not sure if that is interfering. 

I also tried adding the computer under myipaddress and user myipaddress\username but same issue

I tried adding both of those ip addresses linked to the host file linked to computer name, but no luck unfortunately.

Awesome @heyr8kb 

Glad to see you found a resolution... & thank you for sharing it. 👍🏻

Nice to see you were able to figure it out and share the solution.  👍
