Compliance>Account Changes>User Account ASP errors

Event Sentry web reports installed on Server 2008 R2. All aspects of web reports working expect for Compliance > Account changes.

Friendly errors are off and I am getting the following error when the search button is clicked.

error 'ASP 0156 : 80004005'
Header Error

/EventSentry/eventsentry_tracking_users.asp, line 1276

  • Hi Matt,

    This error is caused when buffering is disabled in IIS. Please follow the steps below to enabled buffering.

    1. Open Internet Information Services (IIS) Manager in the “Administrative Tools” folder.
    2. Navigate to Web Sites - Default Web Site - EventSentry.
    3. Right-click EventSentry and click the Configuration button under “Application settings”.
    4. Select the Options tab and ensure that Enable buffering is checked.
    5. Click OK to save the settings.

    Are there similar instruction for IIS 7.5?

    EDIT: All good, found it.

    Up to step 2 is correct. For IIS 7.x the next steps are as follows.

    3. Double click ASP
    4. Under the behavior heading set Enable Buffering to True
    5. Click apply (top right corner)
  • Thanks for the update Matt,
    has been updated to include the steps for IIS7 as well.
