What I need a way to associate a client name or IP address with an open file, so that I can cleanly close the file for maintenance. NET SESSION doesn't show the names of open files and NET FILE doesn't show the client which has the file open. I had hoped that I could cross-reference the data from these two commands, but that doesn't seem doable. Everything else I've see provides the same data as these commands, with no apparent way to determine which client machine has the file open.
