Appendix C. Troubleshooting and Help
Sometimes we buy technical books because we are having specific problems and cannot find good answers elsewhere. However, we often find the answers to our questions buried within the text in places where we might not have known to look, and only after hours of reading. In the interest of finding answers to specific problems more quickly, we have attempted to cross-reference some of the key troubleshooting material in this book by the various Windows error codes we encounter in our daily work. This list is by no means comprehensive and it does not replace the book's index, but it should help many readers get "unstuck" more quickly.
All of the errors introduced by an error code will come from System.Runtime.InteropServices.COMException in version 1.1 and System.DirectoryServices.DirectoryServicesCOMException in version 2.0, which are the two standard exception classes used in System.DirectoryServices (SDS) for relaying errors from the underlying ADSI interface. In some other cases, another .NET exception may be thrown, in which case we mention it directly.
