    Do consider VDI using thin client.
    I would use FAT VDI in CAD and art.

    Also I would have Core that is fiber only and top of cab switches in the server racks it will make wiring easier.

    In the coms racks go interleaved this does not look as nices as some techniques but it pay dividends down the line.

    24 port Patch panel
    0.25, 0.30 or 0.5 patch cables
    48 port switch
    0.25, 0.30 or 0.5 patch cables
    24 port Patch panel
    24 port Patch panel
    0.25, 0.30 or 0.5 patch cables
    48 port switch
    0.25, 0.30 or 0.5 patch cables
    24 port Patch panel

    You may end up missing switch in this design but leaving space for then at a latter date.

    Great provisional plan, I would do something simular. My only advise is dont set it in stone, makesure you have the flexibility to change what works for you. and I would definatly drop XP and opt for win 7. Also make sure you use a knowledgeble company to buy off as they can be the pinacle of good support.

    I'd love a challenge like this

    - Upgrade the DC's to 2008 R2
    - Create 2 file servers for redundancy. Consider DFS
    - Run all other servers on Hyper-V
    - Migrate to live@edu (seriously no one is installing bloated local exchange servers any more. Its pointless and yesterdays technology)
    - Use SSD drives in the clients to increase real world speed for users
    - Ditch profiles

    Thanks. Network infrastructure (switches etc) is already all in place

    Its the biggest improvement we made in our school. Surprising really as it was so easy to do with a massive benefit to the end user.

    To be honest they wont really care about virtualized servers or updated domain controllers so much

    Whatever you do... document!

    The best thing I've ever done was set up our IT Sharepoint site; everything I do is logged on there... user requests, change management, knowledgebase, backup schedule and so on. That way when you come back in 6-12 months wondering just how you set up that awkward bit of software or what you did to the core switch config you'll have it all there for easy reference

    Btw virtualise, EES licensing, SCCM for deployment \ management and have a look at VDI (although I still don't feel it's hit that maturity \ value for money sweet spot yet)

    I think that Citrix's VDI in a box is trying to get there. But for management thin client a much better in the abused and the room with IT round the (edges I stupid idea unless you have big rooms!) Also with the idea that schools now have extended opening it is difficult to get time in the rooms.

    There's a difference between "Not locked down" and "users can see it" and its not clear from your post which one of these issues you're having. I can see why you may prefer to hide some things to stop users playing with them, but if permissions are correct then the fact that things are visible isn't a security risk, and if permissions are not correct then hiding something won't stop a determined user from being able to do bad things with it.

    Accessing local drives is fine, providing that permissions are set correctly to prevent them viewing altering parts of the workstation that they should not have
    access to.

    Browsing network shares - again likewise, browsing shares isn't a problem per se (though I agree it may be undesirable). What matters is what they have permission to do; permissions need to be set on "staff only" shares to keep students out, or on "SMT only" shares to keep students and 'normal staff' out.

    The command prompt - again simply having it is not a problem as they shouldn't be able to run commands that are harmful to the system if permissions are set correctly.

    As for RDC - If you're saying that any user can actually LOG IN to any server via remote desktop then this is indeed a problem, because that means that someone's been playing with the default permissions on those servers. Simply being able to run the remote desktop client and connect to a server and be asked for a login isn't a problem, by default anyway, as non-admin users do not have permission to log into servers*

    (*except terminal servers, because of course the point of these is that users can log into them...)

    I'd suggest you need to determine exactly what users can do (not see) and then fix any permission issues you find because these are fundamental to securing your network. with that done, you can then worry about anything you wish to hide because you don't want users to see it... a completely different and separate issue to securing items.

    A quick update!

    In three weeks or so, I have managed to achieve what I think many wait a lifetime for!

    - New air conditioned server room
    - New ICT Support office + repair area (two separate rooms all kitted out with new stuff)
    - £22k worth of new server, including a hyper v solution based on a SAN for resiliency
    - 90 new PCs ordered - i5s with 4GB and 60GB SSD and a 22" screen
    - set up EES
    - setting up a biometric fingerprint registration system
    - revamping the entire network from ground up this summer
    - Creating an ICT Hub with a brand new IT Room, including a Wii, Xbox connect and various other toys and gizmos.

    So, er, yeah, Going well. Even did my first SIMs update this week.

    So, it happened. I did it. All change!

    This summer, my budget of £160k has paid for:

    Brand new Hyper V Fallover CLuster with a SAN to boot.
    Brand new domain, every machine rebuilt and all running windows 7 64x with office 2010
    90 new Novatech all in one machines with 22" screens and SSDs to refurb every room, and an IT room.
    A brand new office and IT repair area built with brand new machines etc for us
    New Server room with air con
    New storage area
    Sitewide CCTV
    Complete room refurb of an it room, with the addition of a 42" LED, and 55" Benq SMART touch screen, new benching, new layout and the machines mentioned above.
    Exchange 2010 setup (almost!!) Impero, SIMS and more all migrated across.
    Sitewide Biometrics

    Think that is it. Apparently more money/fun to come!!

    And I thought I'd been busy...

    Firstly: gratz! The smug sense of satisfaction must be wonderful.
    Secondly: pics or it didn't happen

    Pics will appear, but we are still finishing off. The main IT room still needs machines in -as we have been using it as a building area.

    got a quick question regarding the nova tech AIO. Looking at their website, the AIO they feature is a celeron dual core AIO, for less than £400. It's 2GB of RAM, but it's still less than the combined cost of many a SFF pentium/core i3 desktop with seperate 22" monitor.

    So i'm asking myself what the performance differences are between that and a £350 SFF desktop ? Or do you sacrifice not having a 5-yr warranty at that price ?
