Remy, I'm using /etc/resolv.conf file & have two entries in it. like nameserver 10.0.0.1 nameserver 10.0.0.2 & tried to check the time host which is somewhere in the range of 48-50, which seems reasonably o.k. I'm also using the default cache size, which I want to increase to some extend. But I'm sure this is not a cache issue. Its surely something related to DNS name resolution problem. ~~~~~~~~~~~~~~~~~~~ Thanks & Regards, Sameer Shinde.
