You experience the following symptoms when you are using Microsoft Forefront Client Security.
In an environment that has many managed client computers, you request an on-demand scan from the Forefront Client Security Dashboard. However, the client computers take many hours to receive the scan request and to start the scan.
During this period, the ScanNow button on the Forefront Client Security Dashboard remains unavailable. Additionally, the following notification appears in the notification list:
Preparing to scan all managed computers
When the Forefront Client Security Management Service tries to import the anti-malware signatures into the Microsoft SQL OnePoint database, you experience one of the following problems:
The import operation fails, and an event that resembles the following is logged in the System event log:
Event Type: Error Event Source: FcsMs Event Category: None Event ID: 10002 Date: Date Time: Time User: N/A Computer: Computer Description:The Management Server Service failed to import the updated antimalware definition.
Details Result code: 0x8007007a Connection string: Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=OnePoint;Data Source=Computer;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=Computer;Use Encryption for Data=False;Tag with column collation when possible=False
The Category Overrides drop-down list in the Forefront Client Security Dashboard contains incorrect items.
Symptom 1 occurs because Forefront Client Security calls each computer individually to run the scan when Forefront Client Security sends a scan request. In addition, Forefront Client Security calls the Anti-malware (AM) scan and the Security State Assessment (SSA) scan as separate tasks. After you apply this hotfix, the individual scan requests are handled in batches to increase performance.
Symptom 2 occurs because of the number of characters in various entries that are in the signatures files. After you apply this hotfix, the entries are truncated to 64 characters.
To resolve this problem, apply the Forefront Client Security Management server hotfix that is described in the following Microsoft Knowledge Base article:
