I have not checked the event log. The computer replaced one with the same name that was in the domain. It had no problems joining the domain. Obivously it is well connected as it has no problem sharing with the other computers, both ways, in the domain, just not one particular one. So ping works and it has an appropriate IP address. The error messages are the same as if the target were powered off: \\admin is not accessible The network path was not found
