Disabling client authorization check on Veeam ONE Monitor Server


There might be several reasons to disable client authorization check on Veeam Monitor Server:

  1. It is necessary to use Veeam ONE Monitor Client outside the domain to which Veeam ONE Monitor Server belongs.
  2. It is necessary to disable or bypass client account authentication to connect to the Veeam ONE Monitor Server from Veeam ONE Monitor Client.


To disable client authorization check on Veeam ONE Monitor Server, follow the next steps:
  1. Log on to the machine where Veeam ONE Monitor Server is installed.
  2. Stop the VeeamDCS service.
  3. Open the registry editor and navigate to the following registry key:

    for v5.x - HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Monitor for VMware\Service
    for v6.x/v7.x - HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam ONE Monitor\Service
  4. Create a new value with the following settings:

    For v5.x

    Type - DWORD
    Name - ClientUserCheck
    Value data (decimal) - 0

    For v6.x/v7.x

    Type - DWORD
    Name - DisableClientUserCheck
    Value data (decimal) - 1
  5. Start the VeeamDCS service.

NOTE: For the instructions to work, authorization has to take place on Windows level. This requires identical accounts with identical passwords to be created on Veeam One Server and Veeam Monitor Client machines if Veeam One is used in a workgroup. Additionally if the registry key noted above is not listed manually create as noted or contact support for assistance.

If these instructions do not help, the problem might be in security limitations of cross-domain network communications. Before running Veeam Monitor Client, use the following command to pre-establish network connection between the two servers:
    net use \\your_monitor_server

You might be asked for security credentials. As a result, the network connection will be established between the Veeam Monitor Server and Veeam Monitor Client workstation. Run the Client to make sure it works.

Please note that disabling Client Authorization is an unsecure way to resolve the problem. Anyone who has Veeam Monitor Client installed would be able to connect to your Veeam Monitor Server, change settings or use remote connection to the virtual machines in your environment via the Console tab.

If you have any questions or problems, please contact Veeam Support at
