Installing Windows NT 4.0 SP4 on SBS Disables Winsock Proxy Client

ID: Q195074

The information in this article applies to:

Microsoft Proxy Client version 1.0
Microsoft Windows NT Server version 4.0
Microsoft BackOffice Small Business Server versions 4.0, 4.0a

SYMPTOMS

Applications that access the Internet and depend on the proxy Dial- On-Demand feature fail on the SBS server; the SBS server may not be able to successfully connect to FTP, HTTP, or Telnet resources on the Internet.

-or-

The WSP utility in Control Panel gives the following error:

WinSock Proxy Client is not installed properly

NOTE: After Service Pack 4 is applied to the client, WinSock fails as well with the same error message as the WSP utility. The Proxy client application is failing on both the SBS server and client. Internet browsing in Internet Explorer is fine.

CAUSE

Installing Windows NT 4.0 Service Pack 4 on a Small Business Server Version 4.0 (SBS) server disables the WinSock Proxy Client component. This problem is occurring because after applying Service Pack 4 the WSP Client was not reinstalled.

RESOLUTION

To correct the problem, reinstall the Proxy Client component after installing Windows NT 4.0 Service Pack 4 by clicking Start, pointing to Programs, pointing to Microsoft Proxy Client, and then clicking Setup.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
