SBS SP1 Upgrade issue!!

[ChicagoRookie]

Hi... Super experts..

I am having problem, when I tried to upgrade to R2 from sbs sp1.

First of all, I got stuck at Installing Sp1..

Everything's looks fine but I got error when I have installed KB88r918-sp1-x86(last step to upgrade).

It said "Installation of the server networking component was not completed."

Plz help me out..!!

Actually our server have two Lan.. But i disconnected one of those..

is it may be problem??

Any suggestion would help..
