I love xtoolbox, save me turning on my PC to transfer games from 1 xbox to another... but i would also like to be able to access my PC from my xbox but im not sure how to setup the host.ini for it... Or to setup my PC... Pretty sure i need my PC to have username and password, which i wouldnt have the slightest idea how to do...

Here's my current Host.ini in xtoolbox if you can make sence from the cut and paste job...

[XBox: IP 192.169.1.210] # Name of remote server
IP = 192.168.1.210 # IP address
Port = 21 # Port number to use
Passive = 0 # Passive mode transfer. 0 = off, 1 = on
KeepAlive = 0 # Number of seconds between NOOP command
Username = xbox # User name
Password = xbox # Password
Initial folder = /E # Initial folder

[My computer] # Name of remote server
IP = 192.168.1.203 # IP address
Port = 21 # Port number to use
Passive = 1 # Passive mode transfer. 0 = off, 1 = on
KeepAlive = 0 # Number of seconds between NOOP command
Username = anonymous # User name
Password = # Password
Initial folder = /C/xbox # Initial folder

You need to set up an FTP-server on your PC. There are lots of good (free) ones out there which come with good documentation and their own support forums.

Once you managed to do that, configuring Host.ini will be easy
