Never come across this. Is the file actually there visible in the Vault View? Can you preview it?
I think I have seen it when someone has created a file in their local vault but has not checked it in yet. The server knows there is a file with a certain name but since the file has not been checked in, the server does not have the file and cannot have anyone else open it.
After some more testing I have been able to confirm that the file is physically in the vault and checked it in just to be safe.
A couple other strange things. When I try to clear the local cache of the user the saem messagebox appears that the "file could not be found".
I had the user log into my machine and he was able to open the file no problem.
I'm starting to wonder if this could be a windows permission issue.
on some occassions i've seen the servers path to the vault shown instead of the local views, ie C: vs D:. Have you tried doing file-open (from solidworks or word or whatever) and browsing to the file?
With the help of my VAR I have discovered what the issue was.
All of our department machines are imaged from a master image. The master image contained a vault view that was already installed.
Every vault view has a unique ViewID number, since various users had the same Vault View ID #, it was causing all kinds of anomolies such as this one and also not allowing some users to get the latest version.
The lesson here is never clone a vault view.
Also if you ever have trouble deleting a vault view because the original user that set up the view is not available to delete it, you can get around it the following way.
1) Open a Command Prompt
2) change to your vault directory CD/vault
3) type "desktop.ini" to launch the file in notepad
4) edit the user name found in "attached by" and close the file
