An event id 560 is just an open event. Check the user's permission carefully. There may be something he/she doesn't have access to like a particular proc or table. Is the message onscreen or is there a failing process? Does the issue occurs with a user with local admin right?
In SQL2000, SQL Enterprise | SQL logins if 'Poll Server' is checked <Tools><Options>[Panel]General, it will generate audit failures trying to poll/acquire data using their domain account(s)
Also, this issue may not be related to SQL server itself. It can occur on a machine with multiple NICs installed.
WORKAROUND:
1. Verify the users logging permissions for the domain, proc, database, service and tables.
2. Because the users are getting Object Access Failure when trying to access a server, you may want to use a third-party tool such as filemon/regmon (which can be downloaded from www.sysinternals.com) to monitor the "access denied" error.
3. If you have multiple NICs, you may wish to temporarily disable the unused ones for testing purposes.
