Unable to Open Three Specific DWG Files from Network Location

Hello,

I'm relatively unexperienced with Autocad, so I apologize in advance for my n00b-ness...but here we go:

I've got two end users who are unable to open a file located on a network drive by double clicking on it through Windows Explorer. I haven't tried File -> Open yet; just read in another post that it may be related.

Both PC's are running Windows 7 (one of the machines was deployed in the past month or two), and I think they both have Autocad 2012. Their server is running Windows Server 2012. It was recently replaced, so my boss and I are thinking it's a bad file path that's being linked with a template or other file.

As far as I know, the problem is only with three files: when the user double-clicks to open, and Autocad is open already, it gets to about 17% and then stalls and the application becomes unresponsive.

If Autocad is not open, it gets to 99% and then the same thing happens (app becomes unresponsive, and have to close out).

How do I determine what files are being linked to from the DWG file? It seems like that's the problem, I just don't know how to go about fixing it.

Thanks in advance!
