Last November, I blogged about a weird bug with SQL Server 2005 on a Windows 2008 cluster.  We were having issues with Database Mail and other things and learned that it was due to the server names being in lower case.  To workaround the issue, we had to follow the steps outlined here as there was no bug fix at the time.  I’ve now learned that this bug has been fixed!  The fix is included in cumulative update package 9 for SQL Server 2005 service pack 3.  Check it out here.
