SharePoint 2010 Publishing | the request was unable to reply to an HTTP 401 request from Application SP2010 of type SharePoint14AAM RRS feed

  • Question

  • Hello,

    I'm facing an issue with SharePoint 2010 publishing with UAG 2010 SP3.

    The current environment is as following:

    - 2 SharePoint 2010 servers

    - 1 UAG 2010 SP3 Server

    - 1 UAG Trunk, contains 2 SharePoint 2010 applications:

            - SharePoint 2010 Portal.

            - SharePoint 2010 My Site.

    All the servers above are in the same domain.

    the issues I'm facing are:

    - Slow browsing for published applications when accessing fro internet or testing directly connected to UAG external NIC.

    - the following event is logged on UAG:

    Event ID 24 "The request from user contoso\test at source IP (external user IP) to trunk SP2010; Secure=0 failed because the request was unable to reply to an HTTP 401 request from Application SP2010 of type SharePoint14AAM".

    This event is always logged when a user is facing slow browsing.

    There was a HW Load balancer for SharePoint (F5 Big IP) and UAG was talking to it, but now we removed it and the same issue occur.


    Thanks, Shehatovich
