Your remark one gets pinged but i can not bring that online. indicates the IP-address is allready in use by another resource (server/PC/network device). An IP-address has to be unique within a network and can only be assigned to one single device. Check which device is currently using the IP-address (PING -a http://www.xxx.yyy.zzz or NSLOOKUP) and assign this device another IP-address or assign a different IP-address to the cluster resource of SQL. Make sure the DNS matches all changes in IP-addresses.
