If the client has already mounted the server using the hard option - and 
then the server goes away, the client will hang on the mount point until 
the server reappears - there is no such thing as a 'timeout' with hard 
mounts ...

However, if you mean reducing the mount failure timeout when the client 
attempts to mount a server that is not available, then have a look at 
the NFS 'retry' option in the nfs man page

But if you are using /etc/auto.net to automount under /net, then this 
uses showmount to find exported mounts from a server, so will error 
fairly quickly anyway if the server is available
