Hi, We have a customer with two event ID's: EventID: 8032 i 8021, Source Browser. When problem appears servers arent available through network, master browser is very slow (my network places is opening too long), network share are unavailable, and sometimes whole server is not available (physical restart helps). Can you advice how and from where to start troubleshooting? Maybe with netdiag and dcdiag? Thanks and best regards.
