NPS Proxy forward request to IAS - 802.x Wired RRS feed

  • Question

  • I have a problem with th NPS proxy(Windows server 2008 Enterprise) and the IAS(Windows server 2003 Standard). The problem is that the proxy forward the request to the IAS and IAS reply grant access but the PROXY doesnt receive the reply, so the PROXY forward the request again. 
    Proxy Server
    Network Policy Server discarded the request for a user.
    Contact the Network Policy Server administrator for more information.

    I think maybe could be a problem with the syncronous timer or wait time between server's.
