SYMPTOMS
If your XML Web service requires NTLM (Windows Challenge Response) authentication, responses to the Web service requests may be slower than responses to requests that do not need this authentication.



RESOLUTION
Note When you install the following fix, you must turn on the UnsafeAuthSharing class. To do so, set HttpWebRequest.UnsafeAuthenticatedConnectionSharing = true. A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next .NET Framework service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:
