we already were discussing this some time ago.
See this thread https://lists.samba.org/archive/samba/2010-June/156387.html

When connected with smbclient you can retrieve the mangled name with
altname DAB11846_17.txt 
DC78E7~1.TXT

You see that the mangled name is "DC78E7~1.TXT", which matches DC*

Jeremy (jra) told me in an internal email that this matches the
windows behaviour, which we should follow.

You can disable this on a share by share basis with
   mangled names = no
