Proxy Server Does Not Correctly Authenticate DPALast reviewed: December 30, 1997Article ID: Q171778 |
The information in this article applies to:
SYMPTOMSWhen you use Microsoft Distributed Password Authentication (DPA) instead of Microsoft NTLM Authentication on Microsoft Proxy Server, users that are allowed access to the proxy server will be granted access. However, users that are not members of the group that has been granted access to the Proxy Server will experience a looping condition on browser. Administrators of the Proxy Server will see log files grow rapidly and will notice that the Proxy Server is busy trying to authenticate user logon requests.
CAUSEProxy Server was not designed to use Microsoft Distributed Password Authentication.
WORKAROUNDMicrosoft Proxy Server has been fixed to provide support for Microsoft Distributed Password Authentication. The fix is installed by stopping all of the Microsoft Internet Information Server (IIS) Services that may be running on the Proxy Server and replacing the W3proxy.dll file.
STATUSMicrosoft has confirmed this to be a problem with Microsoft Proxy Server version 1.0. This problem was corrected in the latest U.S. Service Pack for Microsoft Windows NT version 4.0.
