hello, I am new to this list, so ... :) short: I seem to have a "share" problem with an app, while it is running I cannot overwrite files that it seems to have "open" - when using an NT server this should work. long :) I have following problem with my Samba server: It is serving for a "distributed" (serves three workstations) proprietary app. That app mostly reads and modifies files thru Btrieve ( I don't like it but I have no choice ) using local btr dll's, I am not running a btrieve server. This app has an "update" (sub)program, that prog is called from within the app and calls windows' "file copy operations" (as far as I can tell the standard windows file copy dialogs appear) to copy/overwrite the install files on the server - then the copied installer is called on every workstation. Everytime I run the update app I get "Could not copy file $bla$. Access denied. In use by another application?" (or alike - the msg is in a different lang). If I do the same manually while still running the app using xcopy it works, but if I try to overwrite any file from within windows (explorer e.g.) while the app is running I get the same error. As far as I can tell, this seems to be a share or lock problem - have been reading all of the man I could find on this issue and played with all oplock and directory/create mask settings w/o success. My other thought was that it is due to wrong permissions but afaik they seem right - now I actually set file and dir create mask to 0777 and force masks to 0775 and no luck. Does anybody have an idea? I'd very much appreciate help b/c I could find anything about this online or in the docs. Thanks. - Lorant
