[HP UNIX B.10.20] NFS Client SubSystem fail

Recently moved a HP Unix B.10.20 system from US to Thailand, and everything is work well in US but after we changed:

1. set_parms ip_address (change the IP to TH range)
2. set_parms addl_netwrk (change the Subnet, Gateway, Domain name, DNS Svr Name, and DNS IP)
3. vi /etc/hosts (to commented entries and add new enteries.)

After rebooted encountered NFS Client Subsystem fail* during the post screen. Check the /etc/rc.log and it shown:


starting up the Automount daemon /usr/sbin/automount -f /etc/auto_master FAILURE CODE:1 mounting remote NFS file system.... "/sbin/rc2.d/S430nfs.client start" FAILED

Any expert can help to guide me through?
