Unable to open the Schedule Discovery Result tab

Updated February 16, 2017


Schedule Discovery Result tab does not open. When navigating to the tab, it results to an error message similar to the following:

Error: Getting unexpected website error - Request time out


NPM 12.x


Edit the value of the minutes timeout (default is at 2).

  1. Go to C:\Inetpub\Solarwinds.
  2. Open and edit the web config file in Notepad:

    <httpRuntime requestValidationMode="2.0"/>


    <httpRuntime requestValidationMode="2.0" executionTimeout="300" />

  3. Restart IIS service/s after making the changes.
