Can you provide some more info...
i.e.
Is Realmd.exe / Mangosd.exe running ok ?
What are your Realmlist info: Realm name / ip addr
Generally:
1) Realm Name CAN NOT be Mangos... it just will not work
2) Realm IP Address should be the server ip address, not 127.0.0.1 (although there are some cases where it will work as this)
3) Timezone must not be 0
