Do not leave master as the default device, database creates without a device
specification will be created in master.

- improves performance
- increases chance of device corruption during failure

Extend tempdb:
size should be about 20% of the main production database's size.


/* configure tempdb to 20 mb ... this command adds an additional
18 meg to the 2 mb already present on the master device */
1> alter database tempdb on device26 = 18
2> go


/* Add local server name */
