The xp_cmdshell option is a server configuration option that enables system administrators to control whether the xp_cmdshell extended stored procedure can be executed on a system. By default, the xp_cmdshell option is disabled on new installations and can be enabled by using the Policy-Based Management or by running the sp_configure system stored procedure as shown in the following code example:
— To allow advanced options to be changed.
EXEC sp_configure ‘show advanced options’, 1
— To update the currently configured value for advanced options.
— To enable the feature.
EXEC sp_configure ‘xp_cmdshell’, 1
— To update the currently configured value for this feature.
