MSS Javascript Error

Hi,

We have done Integrated Windows Auth using IISPROXY 1.6

We have implemented MSS & ESS . When we access MSS -> Reporting workset through portal directly we are not getting any error. When we access the MSS -> Reporting workset thru IISPROXY we are getting Javascript error. Do we need to specify anything in IISPROXY.XML?

Thanks & Regards

Vasu
