Hello,

Today, the backup of our domain controller is no longer working and we can't access the host. Everything was working fine until now.

17/11/2024 21:00:44 Failed Unable to install backup agent: failed to connect to "domainename" Error: Account restrictions are preventing this user from signing in. For example: blank passwords aren't allowed, sign-in times are limited, or a policy restriction has been enforced. Failed to connect to share '\XX.XX.XX.XX\ADMIN$'.

The package is accessible when I try to access it manually. I don't understand. The account entered is the domain admin account and even with another account, it doesn't work.

I've scoured the forums and I can't find anything.

Could someone help me?

 

Regards


 

Hi ​@Infra ALAINE -

Welcome to the Community. Needing more info here, though not entirely sure we can assist. I’ll start off with saying your best bet is to contact Support...even if you’re using free version of whatever Veeam backup product, you can still contact Support. 

So, what product are you using?..VBR or Agent for Windows or combination of both? What are you trying to do?...backup, recover, or both? Is your domain controller down? If so, and you’ve used domain accounts for everything, then the error you’re getting makes sense. If you’re using Veeam Agent for Windows, you can check the logs and see if anything definitve shows there:

C:\ProgramData\Veeam\Endpoint\

or, for VBR:

C:\ProgramData\Veeam\Backup\<job-folder>\<job-name>.log

Please provide more info and we can try and assist.

Thanks.

Hello,

Thank you for your feedback.

We use Veeam B&R Community to back up our servers. Our domain controller has no problems at the moment.

We will examine the logs and report them here.

Based on the error you are getting you should check your domain health to ensure it is functional.  To me that is where there failure points to but checking the logs will also help.

it's very strange, it worked a little while ago and my domain is fully functional...

Can you try another account for the backup instead of the Domain Admin to see if that works?  Maybe create a service account with domain rights to test.

i have tested with another account with domain admin privilege, and the result it’s the same

Then you will need to see if the logs can point you to the issue or symptom otherwise I would suggest a Support ticket at this point to get better assistance.  The community is not technical support and we offer as many suggestions as we can to try and help.

J’ai ouvert le ticket et jattend le retour. Voici un extrait des logs :
