Whose got my DAC?
What is the DAC?
The Dedicated Admin Connection, Commonly called the DAC is used to manage SQL Server when a regular connection wont succeed. Here's what SQL Books Online (BOL) has to say about the DAC «This diagnostic connection allows an administrator to access SQL Server to execute diagnostic queries and troubleshoot problems even when SQL Server is not responding to standard connection requests.»
DAC Errors
Occasionally, while troubleshooting SQL servers in a large environment, especially one thats managed from many different geographic locations you could come up with this error, if more than 1 person is using the DAC. It should also be noted this only happens if you have remote DAC enabled in your environment
Error 17810
PASS Value Allocation
Listening to the SQL community over the years, I thought Id take a second to put a quick thought out about why I believe PASS makes almost every decision it makes as an organization.
As a non-profit, Its all about money value, and its use to support the community. Almost every decision that is made within the organization has a value cost, whether that value is actual dollars that need to be spent, or if its a volunteers time, nothing is free or limitless. Just because Microsoft decided that the top tier SQL engine will now cost 58k per processor, doesn't mean they are giving that money away freely to user group organizations.
If you're unhappy with where the organization is allocating its resources, Contact them directly, or probably even better contact all of the board of directors (protip: email format ) let them know you want things to have a different priority, if that fails, they have elections every year, VOTE!
