Internal Processing Error at 0270: 0Bf8 with LMSM (100650)

SYMPTOMS

When you reboot after installing LAN Manager services for Macintosh version 1.0 on a system with LAN Manager version 2.1 or 2.1a and TCP/IP, you get an internal processing error at location 0270:0BF8 and the machine hangs.

CAUSE

The LAN Manager services for Macintosh work with NetBEUI, but encounter this problem with TCP/IP because of conflicts created by the ordering of TCP/IP and Appletalk drivers in the CONFIG.SYS file.

WORKAROUND

Edit the Device= and Run= lines in the CONFIG.SYS file so that the Appletalk drivers are listed first.

Boot from the HPFS recovery disk for the HPFS file system or from an MS-DOS diskette for the FAT file system.
Copy the CONFIG.SYS file to a floppy disk so you can modify it on another workstation. Rearrange the appropriate lines so that the Appletalk drivers precede the TCP/IP drivers. Use this order:
```
      Device=c:\lanman\drivers\protocol\appltalk\atalk2\atalk2.os2
      Run=c:\lanman\drivers\protocol\appltalk\atalkini.exe
```
Save CONFIG.SYS and copy it back to the server.
Reboot the server.

This problem doesn't occur if LAN Manager version 2.2 and LAN Manager Services for Macintosh version 1.0a are used.
