We seem to get internment "FILE ACCESS DENIED" errors when creating or modifying files from a program called MBS (Metal Building Software). It basically hits the file server hard in creating and modifying files related to the job in MBS. It doesn't happen all the time but it is random when it does come back and when it does, they usually get several across a few day period. And oddly, it does seem to be the same people who get it.
It doesn't seem to be a certain file that it is "making" as it is random. It just stops with that error, they go back to the top where it says AUTO and make the cells again and it will usually work (but sometimes providing the error one more time)
The only commonality is the users who get this error also use Lync Messenger. But if I turn Lync off for a few users (but not uninstall), it still happens. The users of this MBS software who do not have LYNC do not get this error. So it seems odd that this can be a coincidence...
If they copy the folder they are working on to their local C drive, the error doesn't happen...so it is something in the network or perhaps permissions.
Because this thing creates and modifies 100's of not 1000's of files when they make the cells, it could be encountering network congestion and it just stops with that error. And it is possible that these Lync users are all on the same switch but I am almost certain one of them isn't.
All workstations are Windows 7 Pro, 64bit and our server is 2012 R2 (VM's)...
I checked the logs on the domain controller, file server and workstation. NOTHING. I've contacted the software company and they are clueless as to what it is. So, was wondering if it could also be network related? Perhaps the switch these users are on?
Any suggestions?
