microsoft Server 2008 Active authentication to a linux server

Hi,

Please could someone advise I'm trying to use winscp from a Window server 2008 R2, but i need to add the authentication key to access the linux rh 5.4 servers ?

What is the best way of approaching this ?
If there are any web links that could help me do this, that would be good.

thank you

Ah, come here, did you try checking out the WinSCP docs on using publick key files...
