There is, although you will need a volume license key
You will need to change a file on the CD so unless you have a cd burner etc?
Look for setupp.ini in your i386 folder open it and it will look something like this:
ExtraData=707A667567736F696F697911AE7E05
Pid=55034000
The PID tells you whether its OEM, Retail or Volume License (Coporate)
Change the PID to 51883270 and it will ask for a Corporate version license key and you wont have to worry about WPA as far as i understand it!!
