Other signs may include sharing violations. Local file operations are not serviced by the server and are not subject to RFCB caching. Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.
Attempt accesses to the file from the local machine.
If you are not able to access the file locally, the remote application might hold a lock on the file or has opened it in exclusive mode. End the remote application and attempt access once again. If this corrects the problem, the application developer should be consulted on their support for running the application on a network. Disable the RFCB caching by modifying the Registry. If this appears to correct the symptoms, you can continue to run the server this way but it will not benefit from RFCB caching.
