consistency job failing

[rashmi.cognos]

Hello,

I am trying to create a consistency job in cognos 8.4 environment. The job is failing while finding inconsistencies with below error:

CM-ADM-4012 During consistency check, an error occurred while validating the search path (CAMID("ADS:u=S-1-5-21-681199449-713514135-316617838-126086")) in external namespace. CAM-AAA-0053 The call to the NTLM function 'NetUserGetInfo' returned with the error code: '2221' ( '{2}'). The user name could not be found.



Mine is cognos 8.4 environment with wintel machine, single server environment.

Please suggest.
