classic asp : MSXML3 dll ServerXMLHTTP

Question

I am using below code

Set objXML = Server.CreateObject("MSXML3.ServerXMLHTTP")
objXML.Open "GET", sendstring, false
objXML.Send()

Its giving error on objXML.Send on localhost environment I dont see any problem in this code but could not able to understand why its giving error. I have already register successfully dll MSXML3 using regsvr32 from location C:\wINDOWS\SysWOW64\msxml3.dll

Do I have to run proxycfg - d ? Please advise

Please see attached error screenshot
