I get the above error in one machine from a VB 6 application. In other machines it is working fine. Also the same kind of code works in a web server. I am using MSXML2.XMLHTTP (changed from servercmlhttp due to another issue). Any way to resolve this or some debug program to figure out what exactly is missing will be helpful.

Hi, try this: 1) open a command prompt 2) write regsvr32 msml3.dll 3) hit enter and try to rerun your app. HTHEdoardo Benussi - Microsoft MVP Management Infrastructure - Systems Administration https://mvp.support.microsoft.com/Profile/Benussi Windows Server Italian Forum Moderator edo[at]mvps[dot]org
