Disable Skype Supernoding

Skype is one of the most popular pieces of VoIP and IM software available.  It is fast, free, good quality, fairly reliable and seems to work almost anywhere. It is also one of the few more secure pieces of communication software, using basic PGP Encryption for calls and instant messaging.

Skype operates on a peer to peer model, rather than a server to client model using is own Skype Protocol and proprietary VoIP Network. This means that the user directory is scattered between "nodes" in the network, rather than using an expensive, centralised infrastructure.

The Zone in question was an Active Directory Integrated Zone, so the first job was to set this as not Active Directory Integrated. Easy enough, in DNS manager, right click the zone and click Properties, on the general tab, click change next to Type, and uncheck “store the zone in Active Directory”.

Once that is complete, navigate to C:\windows\system32\DNS and locate the file containing the local copy of the zone, this will be named the same as the zone you have just amended in DNS Manager, in my Case GlobalNames. Open this up with Notepad, and below the ZONE RECORDS heading you will see the DNS entries listed, these are in tab delimited format of;
