APPEND= with NISAM STOP Produces “Cannot Deinstall NISAM.EXE”

2.10 MS-DOS

Summary: If the network commands shown below are issued in the following order, the NISAM STOP command will generate a “Cannot deinstall NISAM.EXE” error message: NISAM START SRV APPEND=.. NISAM STOP The reason for this is that NISAM.EXE/ISAM.EXE chains itself to the same interrupt as APPEND (Int 21h). Thus, the Int 21h vector initialized by NISAM.EXE/ISAM.EXE is modified by the APPEND command. The problem does not occur if the APPEND command is placed outside of the NISAM START/STOP commands. This is a known problem in Version 2.1. Microsoft is researching this problem and will post new information as it becomes available.
