SYMPTOMS

When you start Internet Services Manager, you may receive the following error message:
The service configuration dynamic link library (the path in the reg value) failed to load correctly: The specified module could not be found.

CAUSE

After you install a hotfix for Internet Security and Acceleration (ISA) Server, three redundant values are added under the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetMgr\Parameters\AddOnServices
The values that are added are:
Web Proxy
WinSock Proxy
Socks Proxy
Adding those values can cause the error message to occur. These error message may also be displayed when you start the Services and Applications object in the Computer Management snap-in.

This is a problem with the hotfix installer, not with the hotfix itself.

RESOLUTION

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.

If you are experiencing these problems, use Registry Editor to remove the redundant entries in the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetMgr\Parameters\AddOnServices
Remove these values:
Web Proxy
WinSock Proxy
Socks Proxy

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
