I've written a vbscript based on the examples provided with BizTalk to unenlist the send ports. When it calls the UnEnlist() method I always get this error, "Provider is not capable of the attempted operation (HRESULT: 80041024)". I've also tried checking the status property, of the port to see if it is already unenlisted, but I always get 3 returned. (which from the help means it's started, but when I look in the BizTalk Admin Console, it's only stopped) Does anyone know how I can get either of these to work? Does the UnEnlist() method need to be run under a specific user? All of the other methods run fine under my current user context. (local admin) Thanks, Anthony
