NFS mount issue

Hi Friends,

My source server is HP and my destination is linux. I have to mount a dir thru nfs from source to destn. almost 8 servers i did the same thing and it is working fine but on the 9th server i can't able to mount.
Everything i have did for nfs configuration.Even i can able to ping across n/w .So i think no issue from network side.But only thing is nslookup is not showing the o/p in destination linux server.
The error is as below,

mount.nfs: Connection timed out

Also when im checking the nfs services status in destn,
rpc.svcgssd is stopped
will it need to be started.
What are the services need to be started and how to.
Waitng for ur reply friends.

Thanks in advance!!!

Please on the Linux box give result of

rpcinfo -p <put_your_nfs_server_here>
