I'm at a complete loss here. Randomly earlier this week, several folders in one of our primary network share disappeared for me and the other IT staff members. I can't figure out what's going on. Security groups are still there, folder still exists on the server as I verified permissions on there. But if I type in the path on my computer, it kicks back the following error:

Windows cannot access \\Servername\Primary share drive\Folder name Check the spelling of the name. Otherwise there might be a problem with your network. To try to identify and resolve network problems, click diagnose. Under details, it’s unspecified error, error code: 0x80004005

In the primary share drive, there's about 12 folders, half are still accessible with no issues, the other 6 all generate this same error.
