Error in Execution of a Job..

I am getting an error while executing a job. Can any one
give an idea how to resolve this...
Executed as user: GECCEFDBY\##MSSQLServer.
cdspcoin1ccefge.master.dbo.xp_fixeddrives [SQLSTATE 01000]
(Message 0) Access to the remote server is denied because
no login-mapping exists. [SQLSTATE 42000] (Error 7416).
The step failed.
Thanks much in advance..If this is a linked server, you may need to set up
an explicit sql server login in order to run this command.
Otherwise, logging sql services in as a domain user or
using kerberos may be required.
