Vault issues. Can see the folders, but can't access them

So the IT guys were attempting to set up a VPN and some how screwed up the vault.  I checked all the vault setting and they seem correct, the issue is when I go to pull something form taht vaulte, the folders and files are faded out.  Also, some of the folders seem to be missing, but I can still see them in the VaultAdmin software and the folders can be seen physically on the server.  Any ideas?SolidworksWorkgroup Pdm
