samba - Jul 2000 - Problem executing file from a samba-share via DOS-client

Hello,

i have samba-2.0.7 exporting a share for a DOS client (NET VERSION
says: MICROSOFT LAN MANAGER 2.2A.0).
Everything is okay - i can map it to a driveletter, read from it,
create files und modify files.
But I can't execute files which are stored on this share - my client
just hangs. If I copy the executeable to the local hard disk i can
execute it as usual.

Any ideas?

Rgds, Adalbert
