No, I should have written 612-626. In other words, the lines to replace
are

 (define csi (make-COSERVERINFO 0 machine #f 0))
 (define mqi (make-MULTI_QI IID_IUnknown #f 0))
 (define unknown
   (CoCreateInstanceEx clsid #f CLSCTX_REMOTE_SERVER (and machine csi) 1 mqi))
 (when machine
   (SysFreeString (COSERVERINFO-pwszName csi)))
