Ok, so this isn't a coding question, but I'm pulling my hair out here. I run a development SQL Server here at my desk, and I need to do some backups on that server regularly. Everything works fine normally, but sometimes, it doesn't do the backups.

My main backup is done to the HD of the server itself, and that works fine. However, I do a secondary backup to a network drive in case that HD fails. I had it setup and it was working great, but I come in this morning and all of those backups failed. And now I can't create a backup device other than to the C drive of the computer the server is on.

I had setup a backup device to the drive of the webserver (different computer), and that worked fine for a while, but now I can't recreate that either.

The thing is, I have about at least 7 or 8 network drives connected to this server, but it doesn't show any of them when I try to create a new backup device.

Does anyone have any clues as to what I could try... or why this keeps happening? The error I keep getting is "operating system error 67 - network name cannot be found"... which is a bunch of crap, because it can see that drive just fine.
