Hi Shawn,
Thanks for the input :) .. I verified the port configuration when i got
that error message.. but could not trace the problem.. As u have suggested I
would try and simulate the same scenario once again.. and update you..
Thanks to everyone for your inputs, i sincerely appreciate it.
Regards
Sajid
