Hi, I've been following this thread in the hope that it would help with a similar problem that I've been experiencing. Alas it doesn't help.
The scenario: I am running a dos app from a shared samba directory on a linux server with both windows and dosemu clients. The problem: When the dosemu clients start the app first, the windows clients get the following message:- Cannot access the file "N:\DATA\EQUITY\EQUITY.EXE". Make sure the file is a valid program and that it is not in use by another program. When the windows clients start the app first, the dosemu clients don't have a problem accessing the program or the data. I've applied the patch to dosemu from the previous posts on this thread with to dosemu 1.1.3 and am using the current version of samba. EQUITY.EXE is a clarion 2.1 based dos app that has been in use for years on all networks tested. Any ideas? Yours, Uwe.
