I have a SQL server that is freezing IO on all DBs 6 times per day at about 2am, 6am, 10am, 2pm, 6pm, and 10pm. These only freeze IO for approximately 2 seconds each time, but it is long enough ...

Microsoft isnt talking dates as to when automatic patching for SQL Server 2000, SQL Server 7.0 and SQL Server Yukon will go live, but its a given.
