We would like to seek some advise from the forum member if KMS were to installed on Windows Server Web Edition, will it violate the MS licensing?

Since IIS definitely will be stopping plus KMS data storage are reside in the same machine!

Coz don't think we really needed a full blown server to host the KMS.

Windows Server Licencing is based on the number of CLTs ( Client Access Licence ) you have. These CLTs only apply to services on the server that require authentication based on the local windows username and password ( referred to as authenticated connections ) this will include file sharing, active directory etc. You basically need one licence per connection or seat depending on your CLT type.

The real clincher is that by default you only get 5CLTS with a copy of Windows Server so if you were to set up sharing on Server 2003 you can have 50 machines using that share but only 5 can connect at the same time.

This is the way Microsoft screw over small businesses because Windows XP/2000 and Vista can also perform file sharing but they are limited to a maximum of 10 such connections so if you have more than 10 machines and say a windows XP file server you will need to purchase Windows Server plus x access licences which means

Anyhow Microsoft call these "Authenticated Connections"

Windows Server Web 2003 doesn't have CLTs they simply dont apply. If memory serves you can't use the server as an AD controller so it has the same restrictions as a copy of Windows XP which is 10 concurrent authenticated connections. In essence Windows Server 2003 web is Windows XP with a few of the server components such as a Full IIS suite and Windows Media Services.

IIS, Apache, Kerio ( if not using AD Authentication ), Any 3rd party software etc are classed as UNAUTHENTICATED connections. This means they don't need to interact with the windows user system or AD user directory and just run over TCP/IP so you can create as many as you want.

I haven't read the licence aggrement for Web Server 2003 but I extremely doubt they will force you to have IIS installed and running as you can use Server 2003 Web for Windows Media Services but if they do simply make it run on port 8080 or similar.

you pretty much hit the nail on the head when you said "don't think we really needed a full blown server to host the KMS."

Kerio will run quite happily on a copy of Windows 2000 or Windows XP there is no real need to purchase server unless you planning on doing Domain Integration or using some over service you only get with Windows Server. Download a copy of Virtual PC or set up a dummy machine with a default copy of Windows and try it out Wink
