SUMMARY
This article defines general guidelines for Microsoft support boundaries for Internet Server Application Programming Interface (ISAPI) issues.



MORE INFORMATION
ISAPI extensions and filters are dynamic-link libraries (DLLs) that are loaded and are called by Internet Information Server (IIS) in response to a Hypertext Transfer Protocol (HTTP) request or event. Microsoft supports the ISAPI interface that is provided by IIS.

Microsoft does not support the following:
 * The location of customer bugs in the customer code.
 * ISAPI extensions and filters that are written by third parties.

For third party issues, the customer must work with the party that creates the ISAPI extension or filter.
 * ISAPI applications where the customer cannot work with the source code to determine the problem.

There are several levels of support that Microsoft provides for customers with ISAPI issues:
 * If no ISAPI extensions work, then this is a configuration issue and is addressed by the IIS Configuration and Administration team.
 * Microsoft supports the process of configuring IIS to use ISAPI Filters. This is a configuration issue and is handled by the IIS Configuration team.
 * If the customer needs help in debugging ISAPI extensions and filters, the Microsoft Developer Support team assists in setting up a debug environment. However, the Developer Support team is not responsible for finding bugs in the code of the customer.
 * Developer Support works with the customer on problems with any ISAPI function calls.
 * Developer Support supports questions or problems that are an issue in the ISAPI environment that customer code is running in or in the IIS architecture.

NOTE: These are support guidelines. Specific circumstances may warrant going beyond these guidelines on some occasions.

NOTE: The boundaries that are mentioned earlier may not apply to consulting or to advisory services cases, which are charged to the customer accordingly.
