Windows 2003 plesk 8.4 – IP address conflict

While working on a windows 2003 server which has a plesk 8.4 control panel, I got the following error:

Unable to add ip xx.xx.xx.xx with mask 255.255.255.0 to interface PublicNetwork, WMI error code 42
Execute file name: C:\Program Files\SWsoft\Plesk\admin\bin\ifmng.exe

This means that there is an IP conflict, to get this fixed – you have to contact your dedicated server provider and ask them to remove the IP address or to provide a new IP address.
