You are working with trust between two windows domains and gets this error.
Are you using vmware… ? yes, keep on reading.
This error does not occur on physical hardware but on a virtualized environment and only in vmware. The problem is the vmware driver  hgfs.sys. This driver handles the “vmware shared folders”.
To resole this disable vmware shared folders. It can be done thug regedit. Se the image below. Just change the “start” key value to 4. The path is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hgfs
