Msg 5832, Level 16, State 1, Line 1
The affinity mask specified does not match the CPU mask on this system.

If you haven’t P2V’ed the system before you do simply change the various affinity masks to 0 which sets them for all processors.  If you have P2V’ed the system your best option is to log into the SQL Server using the dedicated admin connection and manually change the value in the system table by using the following query.

update sys.configurations
set value=0
Where Name = 'affinity mask'

Hopefully you never run across this problem, but if you do there’s the solution for you.

UPDATE: Paul Randal reminded me that CPU Affinity has been deprecated as of SQL Server 2008 R2 so you’ll probably not want to be configuring the CPU Affinity anyway.

I can’t stress this enough.  Actually reading the error messages when there is a problem is key to solving the problems.

Most of the time (I admit, not all the time) SQL Server will give you some very useful information about what to do next.

Recently someone posted the following error message and asked how to resolve it.

Msg 682, Level 22, State 148, Line 1
Internal error. Buffer provided to read column value is too small. Run DBCC CHECKDB to check for any corruption.

Now just by reading this error figuring out the next step should be pretty easy.  Run DBCC CHECKDB and post that information, or better yet after it runs and tells you that there is corruption in your database, follow the instructions that it gives you.  Why should you do this?  Well because when you post this error message on a forum you will be told to go and run DBCC CHECKDB and report back.

Those that answer questions online don’t have any magical power to know what’s happening on your SQL Server.  If you don’t read the errors and follow what they tell you, we are not going to be able to help any beyond that.

My rant now ends.
