So basically we have a client whom on their Fileserver, contains a shared application which is their client management software which everyone runs. However there is one user which gets the following error when they try to run from the share, and the only thing which appears the resolve the problem (but only temporarily) is rebooting the machine.
The error is just the standard Windows cannot access this file.... but when looking at the security from their account - "requested security information is either unavailable or cannot be displayed"
But he can log in with his domain account on another machine and access it fine so evidently permissions are correct, which I've checked. Any ideas?!
