Outside Contractors Can't View Our SolidWorks Files

Hello Community,

This may not be a SolidWorks issue, but lets see. We have been trying to connect some contract workers to our SolidWorks server/files, but we have not had success. We have been able to get the contractors to view our file structure, but they can't view the files.

One issue that my admin and I can think of is that when he set SolidWorks up, he used Windows credentials from our domain for the engineers to log into SolidWorks. Since these computers are not from the local domain that our SW server is on, could this be causing a problem?

Does anyone have any ideas?
