Solution
Ensure the correct account is used
To use VIX for Guest Processing, one of the two following accounts must be specified for Guest Processing:
- The Built-in Administrator (i.e., hostname\Administrator)
Note: This must be the original Built-in Administrator who has a SID that ends in -500. This user is unique and has the ability to bypass Windows User Account Controls. Even if the account was renamed, it will work.
- The Domain Administrator (i.e, domain\Administrator)
Troubleshoot VMware Tools
- If issues with VIX connectivity persist, confirm that VMware Tools is up-to-date for the VM to be protected.
For information regarding issues when upgrading VMware tools, please reference: https://kb.vmware.com/kb/1001354 - Uninstall VMware Tools, and reinstall VMware Tools.
For information regarding uninstalling VMware tools from the command line: https://kb.vmware.com/kb/2010137
Note: If the Veeam Server, which acts as the default Guest Interaction Proxy, is in an isolated network, separate from the production VMs, RPC will fail. In such a situation, building a dedicated Guest Interaction Proxy
that sits in both the isolated and production networks may be preferable to allow for RPC-based Guest Processing.
More Information
For more information regarding disabling UAC under 2012 and 2012 R2, please review the following: http://social.technet.microsoft.com/Forums/windowsserver/en-US/0aeac9d8-3591-4294-b13e-825705b27730/how-to-disable-uac?forum=winserversecurity
In a blog post regarding Windows 10 and UAC Microsoft has stated "Disabling UAC on Windows 10 puts you into an untested and unsupported configuration. It also blocks your ability to run many modern applications."
