    Introduction

    The Management Console displays the following message for the upload of events: Test failed but no further BITS Error invormation is available

    Detail

    Microsoft UrlScan is installed on the Management Server(s).

    Microsoft UrlScan is a security tool that restricts the types of HTTP requests that Microsoft Internet Information Services (IIS) will process.

    By blocking specific HTTP requests, the UrlScan security tool helps prevent potentially harmful requests from reaching the server.

    UrlScan is implemented as an ISAPI filter that screens and analyzes HTTP requests as IIS receives them.

    As an initial test, UrlScan could be uninstalled to prove that this is root cause of the failed upload.

    Following on from this, you can edit the following file to modify the UrlScan configuration:

    %windir%\system32\inetsrv\UrlScan.ini

    The two main sections of the UrlScan.ini file that require editing are:

    1) MaxAllowedContentLength specifies the maximum allowed numeric value of the Content-Length request header.

    For example, setting this to 1000 would cause any request with a content length that exceeds 1000 to be rejected.

    Modify the MaxAllowedContentLength value to 40000000 as some of the strings for Management Server are above the default value of 30000000.


    2) Also within the UrlScan.ini file, ensure that UseAllowVerbs=1

    Check the entries for [AllowVerbs]

    The following is in the list by default:
    GET
    HEAD
    POST

    You may also need to add:
    BITS_POST

    Note, UrlScan 3.0 added change notifications for the UrlScan.ini file, so it is no longer necessary to restart IIS after updating your UrlScan.ini file.
