Hello Henry,
thanks for the reply. I'm having no trouble with other RHL 9 systems
which is having same Autofs version i.e. 4.1.2. In fact few days back I
added one RHL 9 system to my network with Autofs 4.1.2 & its working
perfectly, the same I've installed on the new system but its not
working, Autofs or mount gives me error for SGI,HP-UX & Sun systems
only.
I'm quiet amazed with this...!!!

thanks,
Pranay
