I have an unusual problem.

i am able to disable telnet by doing the following..

config t
line vty 0 4
transport input ssh

and it works..as soon as I logout of the router..telnet is back on
again.

Is that normal?

make sure vty 5 - 16 is also configured for "transport input ssh".
your telnet session may be going to vty lines 5 and on.
