Error while importing option “6.” “This option conflicts with the existing option “An Internal Error Occurred”

Hi,

In one of my migration process, I have encountered with expectable message error while I tried to move DHCP server to Server 2008R2.

In order to the perform migration process, we have to use on CMD or POWERSHELL commands. (Netsh)

netsh dhcp server import c:\dhcp.txt all

The error message you might get is:

Error while importing option “6.” “This option conflicts with the existing option ”An Internal Error Occurred

It happens because when you install the DHCP Server role it automatically created two entries under server options:

006 DNS Server 

015 DNS Domain Name

You should delete them and then run the command again.
