Port 80 on IIS RRS feed

  • Question

  • Hello All,

    I have query regarding the a share point application. We developed an Share Point 2010 application say X,Y,Z, on certain port numbers, say X:1234, Y:5678, and Z:9012 and we extended them to port 80. In our Farm we installed the solutions on the Application Server say 'A'. Now we did Alternate Access Mapping for those applications on the Web Front End Servers say 'B','C'. We gave Host Headers to the applications so that they all are present on port 80 in the Application Server. 




    Now we need to do Load Balancing to those two WFE Servers. But When we gave the Servername:portnumber/landingpage.aspx for the applications it did not show up, like http://servername:80/ or http://ipaddress:80/ We used NTLM for the application and when extended to port 80 its Kerberos. Will that cause any issue?

    How do we do the Load Balancing to those two WFE Servers. I can see the applications on B and C in the Inetpub folder with the port numbers and the extended to port 80. And I can see the site opening from IIS from the Application Pool when we hit the link under Browse to view the site.

  • Hi,

    not sure if this is the right forum for your question ;).

    But I was interested on your description. I think the port 80 is reserved from other application --> I would expect the IIS in your case.
    You can check this with the TCPview.exe tool which is part of the great sysinternals suite.
    I know that some application like to reserve specific ports for your "own" usecase. But if this port is blocked or used from other applications... re-route the port using.
