I am administering a WinNT4 server running IIS4, installed is the XML parser 4.0sp1

When trying to access an xml page, we are getting WINHTTP5.DLL or higher must be registered to use the ServerSMLHTTP object.

This was working fine a couple of days ago, to my knowledge nothing has changed on the server and I have tried to unreg and reregistered the winhttp5.dll with no effect.  Should I try reinstalling the xml parser?

Thanks for any help.

Probably only after the reboot was the change effective. The WinINet component seems to be a bug-bear at MS since it gets changed often. There is a new INet componnet required. See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/htm/sdk_dependencies_9po5.asp

for full details.

WINHTTP5.DLL is part of the WinHTTP 5.0 SDK. This can be installed from here:


The latest version of WinHTTP however is WinHTTP 5.1 which uses WINHTTP.DLL.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winhttp/http/winhttp_versions.asp This is installed as part of Windows 2000 SP3 or Windows XP SP1. I suggest you install this.

you may also need to run the proxy configuration tool http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winhttp/http/proxycfg.asp. I think however this is only necessary for WinHTTP version 5.0 .

Hope this helps,
