Hello Alok,
 
what is your exact new FQDN? is it "RAM_D1_Rhel5-64_192.168.1.41.xx.com" if yes then you need to remove IP address from it. as in DNS every "." is considered as one child domain. Also in your windwos DNS server check all host entries. is you have same IP with two different host names.  thesn rectify it
