samba - May 1998 - DOS-Client with TCPIP and SAMBA

Hi there,

I have a client in a network using a samba-server that has to use MSDOS, because
some software running on it needs a clean DOS. I installed the DOS-Client for 
TCPIP that is available from Microsoft V 1.0 and it works fine; the only thing 
is, that it takes so much memory below 640 K, that another program also running 
under DOS does not function correctly anymore. Maybe some of the programs loaded
in the autoexec.bat are not neccessary or maybe there is some other TCPIP client
for MSDOS available that eats up less memory. A listing of autoexec.bat and 
memory-map (made with mem /c) follows. In case LPC is loaded into high 
memory, things get worse. Any suggestions, thanks in advance?!

Thanks for listing the AUTOEXEC.BAT and the MEM /C output. 


It's clear that you're using the FULL redirector.  The easiest way to
save loads of memory on the client PC is to use the BASIC redirector.
You lose some functionality on the client and you _MUST_ use encrypted
passwords at the Samba server.  (The MS-Client (basic) is naughty in that
it ignores instructions to use plain-text passwords)


I don't remember ever finding bits tht can be removed from AUTOEXEC.
Also, if you want to try and do better meemory managment yourself (I
notice you had 50+K free in Upper Memory) then you should comment out
UMB.COM while you try.  UMB.COM is a special memory manager itself.


Best of luck.
