Best is to work with your Aruba partner or Aruba TAC Support. Timeouts can have multiple reasons, like client settings, MTU issues, authentication server timeouts. In this case, it may be that you have the EAP server root certificate in the Windows User certificate store, and not in the Computer certificate store.
Not that I think it is related, but ClearPass 6.7 is end-of-support and I would suggest to upgrade to a recent version.

Hi, did you ever get it solved?
I'm facing the issue only with computer authentication in wired and wireless, clearpass version 6.7.4.107401.
Everything works fine with user authentication.

I faced same error code 9002 but with different error message in access tracker as below:
"MSCHAP: AD status:{Device Timeout} The specified I/O operation on %hs was not completed before the time-out period expired. (0xc00000b5)
MSCHAP: Authentication failed
EAP-MSCHAPv2: User authentication failure"
And sometimes user authentication faild 2 or 3 times before success login.
any idea ?
