To create your own NatICQ server you need to:
1. Have Internet with static or dynamic IP address with direct connection to network (e.g., ADSL, but not via proxy)
2. Download the server itself and unpack it to any folder you like
3. Add run.bat file to Windows start up programs or to the Task Manager, or you can load server by your own every time. After launching run.bat you'll watch the empty black window opened - don't worry, it's normal 
4. Go to this site and register your own account and confirm this registration via e-mail
5. Create your host
6. Download program for IP renewal (for those who have dynamic IP address), setup it and input your properties (login, password, and if nessesary - program start at Windows start up)
7. If you use Firewall - configure it, permit network connection via port 5050
8. In NatICQ config input the created host and port 5050
