hey mark

thankyou for the mail

and now its seems working

this is the etc/export on the server

/home/users 10.4.139.3(rw,no_root_squash,async)
/srv 10.4.139.3(rw,no_root_squash,async)


and the clients etc/fstab is

10.4.139.2:/srv /srv nfs rsize=8192,wsize=8192,timeo=14,intr
10.4.139.2:/home/users /home/users nfs rsize=8192,wsize=8192,timeo=14,intr

this is working at the moment

but i dont know wen it will stop working :)
