2003 Server Vs 2008 Server

-

i have vb.net webservices , console apps run fine on 2003 server receive below error when trying run on 2008 server.  proxy used both 2003 , 2008 servers same, on same network, in same data center.  has else had issue , know start looking resolution? i'm assuming there configuration change needs occur on 2008 servers i'm not sure look.  web , knowledge base have not pointed me in direction.

here error i'm receiving:

unhandled exception: system.net.webexception: remote server returned erro
