NFS access failed .... error 5 (RPC: Timed out)

Mon Jan 30 11:32:34 UTC 2006

Hi,

We have a RHEL AS 3 (Kernel 2.4.21-20.ELsmp on an i686) as our NIS and NFS
server.

Today while loging, using a NIS account, on one of our servers (a solaris
server), I am getting the following error.

login: gpunam
Password:
NFS access failed for server bangapps.bea.com: error 5 (RPC: Timed out)
No directory! Logging in with home=/
Last login: Mon Jan 30 11:34:33 from 172.22.45.128
Sun Microsystems Inc.   SunOS 5.10      Generic January 2005
-bash-3.00$

I tried to login directly on the NIS server, but cannot login....looks like
the system is now stopped responding.  I had to restart the server.
How do I go about finding the root cause for this issue. Please suggest.

Thanks & Regards,
