Finder throwing error -1401 when attempting to open files on mounted volume

Question

Alright, this is driving me nuts. At random, Finder will refuse to open files on a mounted volume on my server. It throws the error "The application can't be opened. -1401" and then "The operation can’t be completed. An unexpected error occurred (error code -1401)." back to back. It doesn't matter what the file type is, as far as I can tell (.jpg, .xlsx and .pdf are on there).
From that point on, I can navigate those volumes to the point that I have navigated them since the volume was mounted at start up, but can't go any deeper into the directories or open anything. Finder also won't eject the volume. I can't open files from within applications, either.
I have to reboot for it to work again.
However, if I jump into Parallels I can open anything on the server. Even Acrobat files, which open in the Mac environment and not within the virtual machine.
Does anyone have any insight to what might be causing this? I searched and can't find anything.
Thanks,
Brian

Restart your computer with the Shift key held down,
and then open the Startup Items folder inside the
System Folder. Throw away all of the aliases you find
in this folder and then empty the trash.
To quit AppleWorks or another application when it
won't respond, hold down the Option, Command, and Esc
keys, and then click the Force Quit button. You
should also use the Disk First Aid application in the
Applications (Mac OS 9):Utilities folder to verify
your hard disk, as something may have been damaged
when you shut the machine down using that method.
