Symptoms

On Microsoft Windows 2000-based servers, Exchange servers fail Kerberos authentication server requests when the computer account password is changed against Kerberos Key Distribution Centers (KDCs) in the network environment. Kerberos authentication server requests are also known as KRB_AS_REQ messages. The following Event message appears in the Security log on domain controllers:

Event Source: Security
Event Category: Account Logon
Event ID: 675
Description:
Pre-authentication failed:
User Name: <ExchangeServer>$
User ID: <user sid>
Service Name: krbtgt/<domain>
Pre-Authentication Type: 0x2
Failure Code: 0x18
Client Address: <ip address>

This scenario can also cause unnecessary traffic on the domain controllers and delays on the mail servers. Additionally, user passwords are automatically changed every 30 days by default.

Cause

This problem occurs because there is a problem in Windows 2000.
