INTRODUCTION

This article introduces an update for the Dynamic Host Configuration Protocol (DHCP) server role in Windows Server 2008 R2.

Currently, DHCP event logging is limited to the scope level. More specifically, a DHCP event is logged only when you change the DHCP options in a particular scope.

After you install this update, a DHCP event is logged when you change the DHCP options at the server level. Additionally, the name of the user who changes the DHCP options and the property that the user changes are contained in the event log. 

The following event is logged in the Event Viewer when you change the IP Version 4 (IPv4) options at the server level:

Log Name: Microsoft-Windows-DHCP-Server Events/Operational
Source: DHCP-Server
Date: Date_time
Event ID: 85
Task Category: None
Level: Information
User: Domain\user name
Computer: Computer name
Description:
Server level option [Option ID - Option name] for IPv4 has been updated by user name.


The following event is logged in the Event Viewer when you change the IP Version 6 (IPv6) options at the server level:

Log Name: Microsoft-Windows-DHCP-Server Events/Operational
Source: DHCP-Server
Date: Date_time
Event ID: 85
Task Category: None
Level: Information
User: Domain\User name
Computer: Computer name
Description:

File information

The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias.

Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    VersionProductMilestoneService branch
    6.1.760 0.21xxxWindows Server 2008 R2RTMLDR
    6.1.760 1.22xxxWindows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
