Hello,

When users visit our website in which cases the database to be queried we notice that the user gets a failure.  From our review of the Windows Event log it appears that the NT AUTHORITY\Network Service login fails.  Shortly after it fails it is able to login once again.  In looking at SQL log below is what we see:

2009-01-08 10:51:11.51 Logon       Error: 18456, Severity: 14, State: 16.
2009-01-08 10:51:11.51 Logon       Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. [CLIENT: <local machine>]
2009-01-08 10:52:07.96 Logon       Login succeeded for user 'NT AUTHORITY\NETWORK SERVICE'. Connection: trusted. [CLIENT: <local machine>]
2009-01-08 10:52:07.96 Logon       Error: 18456, Severity: 14, State: 16.
2009-01-08 10:52:07.96 Logon       Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. [CLIENT: <local machine>]
2009-01-08 10:52:16.42 Logon       Login succeeded for user 'NT AUTHORITY\NETWORK SERVICE'. Connection: trusted. [CLIENT: <local machine>]
2009-01-08 10:52:16.42 Logon       Error: 18456, Severity: 14, State: 16.

From what I find on the web it appears that the database is incorrect.  However, once we reboot the system everything works without a problem.
