I have two servers: SP01(sharepoint) and SQL01(database). At last time Sharepoint gives me error "Farm is unavailable". After SP01 rebooting, error longs 10-15 minutes, and starts to work normally. I thought that the reason is in connection between SP01 and SQL01, but there is ok. SQL01 is available from SP01. I've edited connection strings and database address from SQL01 to static ip-address, but no result.
Anyone faced with the same situation?
