Problems Accessing and Displaying Web UI

Access Denied

If using the default Log in using Windows credentials check box, the current user account must be a member of the Veeam Virtualization Extensions Users group.

If you run Mozilla Firefox and try to access the web UI remotely using the Login using Windows credentials option, you will need to perform an additional configuration:

  1. In the address bar, enter about:config.
  2. In the list of configuration options, find network.automatic-ntlm-auth.allow-non-fqdn.
  3. Set the network.automatic-ntlm-auth.allow-non-fqdn configuration option value to true.

To log in using different credentials of the Veeam Virtualization Extensions Users group member, clear the Login using Windows credentials check box and enter the user name and password for the administrator account.

Login using Windows credentials check box not displayed

When a distributed Veeam installation is used, where the VE Service is installed on a different server from the web UI website, the Login using Windows credentials check box will not be available as account delegation across servers is not supported.

Page does not display

Check your browser settings to ensure the web UI site is included in the list of "Trusted sites" (in IE, go to Tools > Internet Options > Security). Alternatively, the Automatic logon with current user name and password option should be selected for the list of "Trusted sites" (in IE, go to Tools > Internet Options > Security > Custom Level and scroll down to the User Authentication options).

Web UI displayed incorrectly in IE with Compatibility View enabled

Web UI website does not support the IE “Compatibility View” feature. To turn it off, click Tools > Compatibility View settings and clear the Display intranet sites in Compatibility View check box.
