You need to be sure, that xp_cmdshell is enabled in your SQL server. It disabled by default.
To enable it, please refer to MSDN
http://msdn.microsoft.com/en-us/library/ms190693.aspx[^]

If it is enabled, then there are maybe not enough permissions to use it.
See information about permissions in MSDN
