If you forget your password for Server 2008 or any server, XP then get this BootCD
Tested on: NT 3.51, NT 4 (all versions and SPs), Windows 2000 (all versions & SPs), Windows XP (all versions, also SP2 and SP3), Windows Server 2003 (all SPs), Vindows Vista 32 and 64 bit, and some say it works on Server 2008 (32 & 64 bit)
It worked for me :)
