COM Internet Services Do Not Work Without ProxyOverride Entry

ID: Q240664

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Workstation version 4.0

SYMPTOMS

After you install Microsoft Internet Explorer version 5 on a computer running Windows NT version 4.0, you may receive the following error message from COM Internet Services:

The remote server machine does not exist or is unavailable (Error 462)

CAUSE

This behavior can occur if you clear the Bypass proxy server for local intranet access check box in Internet Explorer options.

In Internet Explorer 4, clearing the Bypass proxy server for local internet access check box sets the following registry value to null:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyOverride

In Internet Explorer 5, the ProxyOverride value is deleted. The Remote Procedure Call (RPC) protocol flags an error condition when it cannot find the ProxyOverride key in the registry.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT 4.0 service pack that contains this fix.
