MSXML2.ServerXMLHTTP and ISAPI_REWRITE problem?

[rvo Profile]

I have (2) servers.

Server A uses ServerXMLHTTP to retrieve a page from Server B.
Everything works.

Today, I install ISAPI_REWRITE on Server B.
I_R works great on server B.
But now, Server A is getting 403 Forbidden Error when it tries to retrieve a page from Server B using ServerXMLHTTP.

The only new thing/change done on Server B is the installation of ISAPI_REWRITE.

Does I_R cause any problems with ServerXMLHTTP? I'm pulling my hair here. This has been working for couple of months without problems until today.

Note: If I ask Server A to GET a page from another website (ex: Google), it works. So my code is not the problem. Something on Server B is now causing 403 Forbidden errors when Server A tries to GET a page.

Hello,

This is strange, but let's try to figure it out...

First, please try to uninstall ISAPI_Rewrite again and make sure the behavior is back to normal.

If it is, please show the rules you are using and see if there is anything in ISAPI_Rewrite error.log.
