Re: Windows 10 in domain connects but fails to manually reconnect

without further details I'd say you checked the 'do not prompt' for certificate..so it was connected but wont reconnect because its not happy about the CA or RADIUS cert. just ensure you've imported the CA used for the RADIUS server into the correct root authority store so that the client is happy with the server cert. you really SHOULD have all those things (CommonName filled and CA selected etc) - if doing a windows domain this is VERY easy with a GPO that can be just pushed to all Windows clients in the domain. alan
