Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Run regedit again and move to HKLM\System\CurrentControlSet\Services\ and remove the old service values from SQL Express from the DependOnService Multi string found in the vCenter services."

A block of code is set as follows:

com.rsa.db.type=MSSQL.
com.rsa.db.instance=RSA. (your RSA instance dbname is)
com.rsa.db.msserverinstance= . (Leave empty when using the default MSSQLSERVER instance on the target server)
com.rsa.db.hostname=destinationSQL server.
com.rsa.db.port=1433.

Any command-line input or output is written as follows:

vi /etc/sysconfig/networking/devices/ifcfg-eth0

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Navigate to Start | Run, type regedit, and then click on OK."
