I have an old proprietary application running on OS/2 until October. These PCs login to our Windows domain for file sharing purposes only. We just upgraded a couple of Windows DCs to 2012R2. We are now having issues. Some OS/2 PCs have no issue logging in and others do. Its random which confirmed for us that those that login to 2003 servers work ok still.
On the OS/2 PC can I make a change to LAN Manager or some INI file that will allow me to login to a specific Windows server?
