Recently I have been seeing quite a few laptops arriving in the office with their NICs set to strange DNS entries. It appears that some home broadband routers are able to overwrite the DNS setting for a NIC and apply some strange IP range. The below script when applied in GPO will reset the DNS back to “obtain DNS server address automatically”.<\/p>\n
If it fails bear in mind that it requires “elevated priviledges”. You can uncomment the wscript line which will give you an error code. 0 = success and 91 = access denied. For a full list of error codes, see this page here<\/p>\n
