Ever since I upgraded to ISA 2004 I have been seeing this error on out Event Log under "537"

 

Logon Failure:
  Reason: An error occurred during logon
  User Name:
  Domain:
  Logon Type: 3
  Logon Process: Kerberos
  Authentication Package: Kerberos
  Workstation Name: -
  Status code: 0xC00002EE
  Substatus code: 0x0
  Caller User Name: -
  Caller Domain: -
  Caller Logon ID: -
  Caller Process ID: -
  Transited Services: -
  Source Network Address: -
  Source Port: -

 

I have seen the issue of time sync and have issued a command NET TIME /SETSNTP: on all the machine in out network.

 

However this seems to have had no result. We have now had around 4800 of these errors averaging 600 a day. The end users see no errors themselves but have been complaining about slow response times when browsing the internet.

 

ISA 2004 is up to date as far as service goes (SP2 plus the extra fixes).

 

Any ideas please?
