c# - wcf custom header working on one server and not the other -

i have wcf service have added custom headers via iclientmessageinspector.beforesendrequest. when send original server (running server 2003 , asp .net 4.0) works fine, header included.

i moved server client , header not show up. server 2008 r2 64-bit net 4.0. code , web.config 100% same. possible difference in server causing this?

note there no errors or anything, not add together header. in addition, other server has iis issue asp .net tab not show up. unable resolve instead used aspnet_regiis set applications 4.0. works fine , dandy except not include header.
