You experience the following symptoms when you are using Microsoft Forefront Client Security.
Symptom 1On a computer that is running Microsoft Windows 2000 Service Pack 4, the Anti-malware user interface cannot open when you log on to the computer by using a non-administrator account.
Symptom 2In the notification area, the Forefront Client Security icon becomes orange to indicate that an issue has occurred. When you open the Forefront Client Security client to view the issue, the client incorrectly reports that a product update is available for the Forefront Client Security client. A product update is not available.
Note In this scenario, the new product update notification differs from the new definition update notification.
Symptom 3When you save a Microsoft Office Word document that already exists on a FAT32 volume, the file disappears unexpectedly. This occurs only when antivirus real-time protection (RTP) is enabled.
Symptom 4The Microsoft Forefront Client Security Anti-malware Service stops unexpectedly. Then, this service does not recover automatically. This symptom occurs if the signature or the engine update is invalid.
Cause 1Symptom 1 occurs because of a permission issue that is specific to Windows 2000. In Windows 2000, a non-administrator user is denied access to the RegisterGPNotification function. This function is used to monitor policy changes.
Cause 2Symptom 2 occurs because a registry value is not reset as expected after a successful upgrade. To determine the current state of Forefront Client Security Agent, the Forefront Client Security client queries the following registry entry:
Note A value of 0 indicates that new updates are not needed. A value of 1 indicates that new updates are needed.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Forefront\Client Security\1.0\AM\ProductUpdateAvailable
However, the Forefront Client Security client update package did not reset this registry value to 0 after the last upgrade.
Cause 3Symptom 3 occurs for one of the following reasons:
Cause 4Symptom 4 occurs because the Microsoft Forefront Client Security Anti-malware Service registers with the Service Control Manager (SCM) to automatically start two times after a failure. If an invalid signature causes the service to stop repeatedly, the SCM makes only two restart attempts and does not continue to restart the service.
