Thanks to several very helpful souls on this list we have been able to replace ndis2 NIC drivers and boot successfully in DOS, map a Samba drive ... permitting us to use a DOS Ghost to build lab systems. The guy who figured this stuff out last year has left the college and I don't understand what protocols, or clients he used to support a DOS-Samba connection. (I'ld be lost if I had to build a boot disk from scratch or fix something more than a change of NIC.) My "netstart.bat" looks as follows.... but source of protocol.ini and system.ini which I haven't copied - is a mystery to me. Does anybody recognize or tell me what this stuff is ..... amd if there is a simpler way to build a DOS disk to make a Dos connection? Is this Microsoft Lan Manager DOS client stuff, NT DOS client stuff ? net initialize nwlink netbind.com umb.com tcptsr.exe tinyrfc.exe nmtsr.exe emsbfr.exe net logon user /yes /savepw:no Dan Mandell Saint Mary's College Notre Dame, In
