Experiences in managing web sever

For the past three weeks i am successfully managing a web server. I have installed sql server 2005 and .NET 3.5. I am using Symantec Backup Exec System Recovery for taking backups. Please see my post about it. I have no problems with the server yet except some hacker attacks, i am regularly getting continuous sql server,ftp login attempts from china, pune(india),korea its are coming from same ip everyday.
