When running the VIETool that is included with Symantec Endpoint Protection on a Unidesk volume, it appears that the VIETool is not taking action on files when expected to.
The nm_tool_service.log shows errors.

Unidesk managed VDI environment
After active collaboration of engineering efforts between Symantec and Unidesk, both vendors came to the conclusion that VIETool and Unidesk volumes are not compatible.
Symantec’s methods of determining what files need to be scanned or skipped with the VIETool is not compatible with the way Unidesk creates and maintains readable and writeable volumes. In order to make them compatible, both products would require major design changes in the way the volumes are created and managed by Unidesk and how Symantec identifies what needs to be scanned.
It is not recommended to use the VIETool on Unidesk volumes due to this incompatibility.
