DHCP Not handing out addresses after importing all settings?

Here is the scenario I ran into… Following the import of all DHCP data from a “soon to be retired” DHCP/DC (2003) to a new DHCP/DC (2008 R2) and the subsequent demotion of the old DHCP/DC, new DHCP leases were not being handed out to clients. The DHCP Server Service was restarted and the following error came into the System Event log.

Looks like following the Import the Bindings are not properly configured, which if you think about it makes sense as the adapter and/or the address would be different.

Here’s how to Configure the DHCP Server bindings.

GPO to map drive. Better than scripts in many ways.

The best way to map a drive is to use Group Policy Preferences, introduced in Windows Server 2008. Group Policy Preferences removes many of the reasons we had to use scripts in the past.

1. Open an existing Group Policy Object (GPO) (or create a new one linked to the domain or OU you want to map to).

2. Navigate to User Configuration, Preferences, Windows Settings, Drive Maps.

3. Right-click Drive Maps and select New, Mapped Drive.

4. To add a new mapped drive for users, select Create (or select Replace to replace an existing map drive that might already exist with the same letter).

5. Close Group Policy.

6. Enter the details for the share, a name, and letter, then click OK (see the screen shot below).

At next Group Policy refresh, during logon, the drive will be mapped.
