SYMPTOMS
A Windows Server 2008-based Dynamic Host Configuration Protocol (DHCP) server that is configured in a workgroup environment may consume too much memory. Over time, the memory consumption may make the DHCP server become slow. Additionally, the memory consumption may make the DHCP server eventually shut down.
Back to the topCAUSE
This problem occurs because of a memory leak in the path that is used for unauthorized DHCP server detection on the DHCP server.
RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To resolve this problem, disable unauthorized DHCP server detection on the server. To do this, follow these steps:
| 1. | Click Start, click Run, type cmd, and then click OK. |
| 2. | Type the following command, and then press ENTER:
reg add HKEY_LOCAL_MACHINE SYSTEM ControlSet001 Services DHCPServer Parameters /v DisableRogueDetection /t REG_DWORD /d 1
|
Note After you follow these steps, you must restart the DHCP server.
