Hi
go to SBS Server
Open the DNS Server Management Console
Click on your Server.
Add a Forward lookup Zone.
Dont change any default Options, Press Next Next and give the name of zone as no-ip.inf
After than Right click on that zone and Add a 'A' Record.
A Record name will be company. and type your IP.
and Finish.
now if you will ping from your PC to company.no-ip.inf it will go 192.168.0.2
Thanks
