| Source | DhcpServer |
| Description | The DHCP service has detected that it is running on a domain controller and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service. This is not a recommended security configuration. Credentials for Dynamic DNS registrations may be configured using the command line "netsh dhcp server set dnscredentials" or via the DHCP Administrative tool. |
| Event Information | CAUSE:
This behavior occurs because you did not configure the DNSCredentials on the domain controller on which you installed the DHCP Server service, and DNS services. This is not a recommended configuration
RESOLUTION: To resolve this behavior, configure DNSCredentials by using one of the following methods: By Using the DHCP Server Snap-In In the DHCP Server snap-in, which is located in the Administrative Tools folder, right-click the DHCP server that you want to configure, and then click Properties. On the Advanced tab, click Credentials. Type the username, domain and password of the account under which you want the DHCP Server service to run. You can use any valid existing user account for this, such as a Domain User account. The account should not be set to expire or have any other restrictions. Click OK, and then OK again to exit the Properties dialog box. By Using the Netsh.exe Command Line From a command prompt, type netsh, and then press ENTER. From the netsh prompt, type dhcp server ipaddress (where ipaddress is the IP address of the DHCP server that you want to configure), and then press ENTER. Type set dnscredentials username domain password (where username domain password is the user account information for the account under which you want the DHCP Server to run), and then press ENTER. You can use any valid existing user account for this, such as a Domain User account. The account should not be set to expire or have any other restrictions. Type quit, and then press ENTER to exit. |
