Following VMWare Tools upgrade from version 12.2.0 to version 12.2.5 on Windows VMs, the Site Recovery Manager IP customization process fails. The error displayed in the Recovery Plan report is "Failed to authenticate with the guest operating system using the supplied credentials".
Inside the guest operating system, "C:\Program Files\VMware\VMware Tools\VMware VGAuth\VGAuth.dll" is missing after VMWare Tools upgrade from version 12.2.0 to version 12.2.5. This issue does not happen when VMware Tools is upgraded to version 12.2.5 from versions prior to 12.2.0, nor a fresh install of 12.2.5.
This issue is resolved in VMware Tools 12.2.6. If you have an affected Windows VM, upgrading from VMware Tools 12.2.5 to 12.2.6 will replace the missing VGAuth.dll file. Please refer to the Download link and Release Notes link below for more information.VMware Tools 12.2.6 DownloadVMware Tools 12.2.6 Release Notes
