Hi; I have a user coming in through a vpn connection. This computer account is not setup on the domain. However the user account and e-mail exists. When the user access his e-mail the following message appears in the logs: Event Type: Failure Audit Event Source: Security Event Category: Account Logon Event ID: 681 Date: 10/6/2003 Time: 9:00:51 PM User: NT AUTHORITY\SYSTEM Computer: srv1 Description: The logon to account: user@xxxxxxxxxx by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 from workstation: srv1 failed. The error code was: 3221225572 The user can access all files on the network including e-mails, but this messgae is bugging the hell out of me. Any ideas how to solve this. I checked Technet but it didn't give me a solution. Thanks in advance
