Microsoft IIS Plugin Unable To Communicate With WebSphere

Technote (FAQ)
Problem
When Microsoft IIS plugin will not communicate with WebSphere.
Solution
Check the following:
  1. If upgrading WebSphere, did this machine have any IIS efixes applied to it before you upgraded? If so, were all efixes removed before upgrading?
  2. When IIS webserver is remote: Is this webserver machine outside of a firewall? If so is DNS enabled for windows resolution in the Winsattribute panel of the Windows NT operating system?
  3. If this webserver machine is inside the firewall, and DNS is disabled for WINS, ensure that LMHOSTS look-up is enabled.
  4. When IIS webserver is remote: Check if you have a WebSphere/Appserver/properties directory and, if so, there is a bootstrap.properties file there. Check that your bootstrap.properties file is picking up the correct install directory for your server.root.
  5. Is security enabled? If so, are you running with any security efixes? Check the WebSphere support website:http://www.ibm.com/software/webservers/appserv/support/index.html for the latest security efixes that may apply to the release you are running.
  6. Is the failing IIS webserver one of multiple IIS web sites on a machine (as defined in the Microsoft Management Console)? If so, see APAR PQ41425 for possible resolution.
  7. If none of the above resolves the problem, you can enable a plugin trace to get more info:
    • Server Side: Enable the plugin trace as follows:
      1. start the admin GUI
      2. select Topology
      3. select your app server (default_server if you are using the default)
      4. select servlet engine
      5. advanced
      6. select settings
      7. check all 4 boxes under "Select Log File Mask" (trace,inform,warning,error)
      8. click 'ok', then 'apply'
      9. recycle app server

    Note: The plugin trace output is written to the WAS "default_server_native.log_inform" file. Conversely the WAS plugin trace entries are written to the default_server_iis.trace.log.
    • Plugin Side:
      1. ose.native.log.level=ERROR|WARNING|TRACE|INFORM
      2. ose.plugin.log.level=ERROR|WARNING|TRACE|INFORM
