Connecting to the guest os via vix error mlocate was not found

veeam connecting to guest os via vix error cannot upload file to admin share

• Veeam: Version 9.5.0.1536 installed on Windows 2012 R2 (Vm guest, part of Domain)
• Vcenter: 6.5 (VM Guest, part of Domain)
• Multiple ESXI 6.5 servers under VC

I am using Domain Controller Administrator account, & getting Error when testing job under «Guest Processing» (although I can access all server’s admin share from the Veeam server like \target_serverC$ etc)

The error is showing for different vm guests example windows 7 , windows 2008, windows 2012.

• Tried disabling UAC (via UAC gui and Registry)
• Added LocalAccountTokenFilterPolicy in registry for 2012 as well,
• Firewall is disabled on all machines by group policy

Popular Topics in VMware

I can say I have gotten this and then the backups still work. Weird, but I haven’t upgraded to the last 2 versions because of a legacy tech I’m currently trying to replace. Try performing a backup on a small VM where the authentication test fails. I bet it still works. Why? I don’t know, but may have been resolved in a later build

problem still exists.

Cheers for trusting us with the spot in your mailbox!

Now you’re less likely to miss what’s been brewing in our knowledge base with this weekly digest

Oops! Something went wrong.

Challenge

Note: The solutions to RPC and Win32 errors apply to the Credentials Tester when used with vSphere, Hyper-V, and Veeam Agent for Microsoft Windows. The VIX Connection issues section of this article is related to VMware only.

Regarding Warning in VMware Environments

In VMware environments, Veeam Backup & Replication can use two methods to connect to a guest: RPC or VIX. If RPC is testing successfully, it is generally acceptable for the VIX test to fail as it will not likely be used. However, if it is desired to have VIX succeed, please see the relevant section at the bottom of the solutions section.

Solution

Important notes about the Account shown in the error:

In some environments, there may be multiple entries in the Credentials Manager for the same account. It is advisable to review the credentials manager and remove duplicate entries. See: https://www.veeam.com/kb3224

If the account specified in the error is different from what is configured on the Guest Processing tab, check under the [Credentials. ] button on the Guest Processing tab to check if specific credentials have been set.

For VM Backup and Replication jobs (VMware or Hyper-V), the account specified to connect to the Guest is always the account used to login to the SQL instance. So the Credentials Tester can show good for a SQL server, but the SQL-related tasks (Truncation, Transaction Log Backup) may fail if the account being used does not have the correct permissions in SQL.

_{This is not an exhaustive list of potential errors. If you have an error not listed here, please use the «KB Feedback/Suggestion» button at the bottom of this article to notify Veeam Support.}

If the error you see is not listed here and you need help, please open a support case.

The following is a few of the possible errors which may be seen in the Guest Credentials Test in the line after «Testing admin share accessibility via RPC»

Just curious if there was ever a solution posted for this error. I am also receiving:

I recently came across this when moving our environment from Hyper-V to VMware, and if your situation is the same as ours the error only appears when executing the «Test Now» button under the Backup Job -> Guest Processing.
In your case, the VIX error you shouldn’t need to worry about (assuming you don’t have any guests that are «networkless»).
You see, when Veeam performs a backup it will first try to connect with RPC. Only if RPC fails will it try with VIX.
As you can see in your above log extract RPC succeeds. Hence you can ignore the VIX error, and there is no need to disable UAC in the guest or to back up as the actual «administrator» login. The backup will work without warnings or errors (well it has for us).

To remove this confusion I think Veeam should not attempt VIX testing if RPC testing succeeds (ie when «Test Now» is executed).

Guest processing

Post by badams » Jan 22, 2018 2:58 am this post

During the setup when I get to guest processing and credentials, I use the same credentials I have used all along. I run the test, and it fails every time. I get a warning on checking standard credentials and a red x on Connecting to Guest OS on RPC. Also, Testing Admin Share Accessibility via RPC and Cannot Connect to the Host’s Administrative Share. Any thoughts?

Re: Guest processing

Post by mriksman » Aug 16, 2018 4:45 pm this post

This is what I am seeing.

I used my personal, domain admin account when I first setup. Backups seem fine — no errors — but I haven’t tried a restore yet (it’s on the list of things to do. ). Log/report says that SQL logs were truncated (which I presume is related to Application Aware processing)

But I decided to create a standalone account. So I made it a domain admin member as well (as I saw this is required for DC backups), and went to modify the ‘Guest OS Credentials’. I clicked Test Now, and all of them have;
A warning next to ‘Checking Standard Credentials’
A red cross next to ‘Connecting to guest OS via VIX Error: Cannot upload file . ‘
A red cross next to ‘Testing admin share accessibility via VIX’

I tried my personal account again, and I too get the same warnings/errors.

So — the test fails, but the backups work.

I read somewhere, to try using the standard DOMAINAdministrator account to get around UAC. I tried this and _most_ of them now pass. Well — Windows 2012×64 and Windows 7 does. But my 2 Windows 2008R2 still fail (although these are Honeywell PCs and as part of their installation, may have extra security policies/settings enforced on them).

Any ideas? Am I missing anything critical with these errors, but the backups are ‘working’?

i can’t add servers on backup job

i can’t add servers on backup job

Post by astoinemicro » Feb 12, 2021 4:17 pm this post

Hi ,after a new installation of veeam 10 on a BACKUP VM , wich was setup on a Vmware ESXI 6.7.0 ,i can’t add all my VM servers on veeam , i keep having this error :
Connecting to guest OS via VIX Error: Cannot connect to host [192.168.50.13] over web services.
Login: [root].
Guest Login: [promadomain.proma.localerjout].
Could not initiate Web Service connection
Could not initiate guest virtual machine [6] with user [promadomain.proma.localerjout]
Could not validate host [https://192.168.50.13:443/sdk] credentials for guest [6] user [promadomain.proma.localerjout]
Could not invoke guest operation
Current license or ESXi version prohibits execution of the requested operation.

The userrname and password are right and have the proper admin permission .
i disabled Firewall rules from remote Servers
Pings are working fine
I can do remote with RDP on those servers
Shared folder are accessible from The backupserver
i reinstalled the Vmware Tools

Do you have any Idea how to resolve this ?

Welcome to Veeam R&D forums!

Is that a licensed or a free ESXi server? If the latter, then this is the case — free ESXI servers are not supported by VBR.

I’ve got an issue on my Veeam 8.0.0.2084.

I use account other than the built-in «Administrator» for application-aware processing.
—

I had this errors:
—

Error: Cannot upload  file to admin share [C:Windows]. Cannot create folder in guest: [C:WindowsVeeamGuestHelpersTest].

VIX Error: A file was not found Code: 4
—

Error: Cannot connect to host […] over VIX. Login: […veeam]. Guest Login: […veeam].

Failed to login to VM: [[…] xxx/yyy.vmx]. User: […veeam].

VIX Error: Authentication failure or insufficient permissions in guest operating system Code: 3015
—

Cannot create folder in guest: [C:WindowsVeeamGuestHelpersTest].

VIX Error: You do not have access rights to this file Code: 13
—

So, to resolve it I’ve done the steps:
—

1. Upgrade VMware Tools (10.0.9 build 3917699) in VM

—
2. Disable UAC in VM (win2012r2) by this key

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionpoliciessystem]

«EnableLUA»=dword:00000000

—
If you use built-in Administrator account, you needn’t disable UAC.

—
By the way, If you want to resolve Veeam RPC issue in virtual machines located in DMZ and not inside the domain, you need to enable Administrative share ADMIN$ by this key

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionpoliciessystem]

«LocalAccountTokenFilterPolicy»=dword:00000001
