I tried to install a new server running Windows server\n2003 into an existing Windows 2000 domain to replce the\nold server. I just performed the steps below\n1. Promote the new server to DC of the existing domain.\nThe AD information was successfully replicated.\n2. Transfer the all operate master roles to the new\nserver.\n3. Enable the Globe Catalog in the new server\nHowever, problem happened when I shutdown the old server\nthat no one could logon to the domain.\nI tried to run the diagnostic tool 'dcdiag.exe' and an\nerror discription was returned.\n"Warning: DcGetDcName(GC_SERVER_REQUIRED) call failed,\nerror 1355\nA Global Catalog Server could not be located - All GC's\nare down.\nPDC Name: \\I-CO.IDOM.DOM\nLocator Flags: 0xe00001f9\nWarning: DcGetDcName(TIME_SERVER) call failed, error 1355\nA Time Server could not be located.\nThe server holding the PDC role is down.\nWarning: DcGetDcName(GOOD_TIME_SERVER_PREFERRED) call\nfailed, error 1355\nA Good Time Server could not be located.\nWarning: DcGetDcName(KDC_REQUIRED) call failed, error 1355\nA KDC could not be located - All the KDCs are down.\n..........................
