error on remotely hosted repo on mac server with smb

[lgroger]

We have a repo that was on a windows server that we would access with Source Tree from our local machines.  They just migrated that Windows server's data to a Mac server running smb and now we get this error when trying to stage a file on the existing repos or on any newly created repos.  I can manually browse to the location and write a file though.  I'd appreciate any insight anyone could provide on what could be causing this.
