I have struggled with this problem often. The primary problem is that the setver.exe that came with your distribution of DOS 6.0 is not lying properly to the rdrload.exe program. There are several versions of setver.exe, some work, some don't. Try the setver.exe that comes with DOS 6.2. The following brute force method has always worked when other methods fail, even with a bad setver. You can load starlan from a bat file after you switch to the DOS 5.0 redir.exe. Here is an example which assumes that the computer name is compname, the servername is server, and the StarLAN 3.2 files are in the attnet directory on the dos pc. This bat file can also be used to set portions of the network software into high memory. attstart.bat @echo off cd c:\attnet c:\attnet\attcfg c:\attnet\iso c:\attnet\vertbl rem parameters for redir from profile.sys c:\attnet\redir /b:2 /z:4096 /s:10 /l:12 /p1:256 /p2:128 /p3:128 c:\attnet\setname compname c:\attnet\prtsc c:\attnet\nps c:\attnet\msgpop ql link n: \\server.serve\attutil call n:\netstart call netstart.bat compname z: server.serve exit
