WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To work around this problem, do the following:

    • Content Index Service
    • IIS Admin Service
    • Microsoft Proxy Server Administration

    • Inetpub\Scripts\Proxy
    • Msp
    • Urlcache (this folder may exist on more than one partition)
    • Winnt\System32\Msplogs

  3. Find and delete the following file, if it exists:

    Winnt\System32\Drivers\Ipfltdrv.sys

  4. Use Registry Editor (Regedt32.exe) to delete the following registry keys, if they exist:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IpFilterDriver

    • MSP@v2.0.372.12 (value for Proxy Server 2.0)

    in the following registry key:

    HKEY_LOCAL_MACHINE\Software\Microsoft\MS Setup (ACME)\Table Files

    Note that some values may not exist, depending on what versions of Proxy Server have been installed on the server.
