Hosted I was told is capped at 1200 students so £2400. A bit cheaper than an emerge site licence (£2950).

Half of our PCs now have Samsung 840 Evos in them. Makes a big difference. Hope to get up to 100% in the next 1-2 years. Forgot to say, we spent about £45 on 120GB Evos back in July based on 100 units. Any old box shifter will do to be honest.

I'm slowly migrating my domains to namecheap for this exact reason.

V=IR So if the current (I) drops, and the resistance ® of the circuit remains the same the voltage (V) will drop also. Ohms Law.

I think someone on here a while ago suggested the Mobius Camera. The quality looks excellent, but it isn't designed to be a dash cam really. You can replace the lens with a wide angled alternative, you can remove the lens entirely from the camera body (useful if you want the install to be as hidden as possible) and you can replace the battery with a capacitor which ensures that recording stops minutes after the power is cut. ~£80 with a cradle and a suitable length of cable. I keep looking at it. I guess it's like a cheap GoPro - there are other mounts and accessories you can get for it. It's not waterproof though.

Some more feedback Dave - this needs some work...

If you are donating your time (well done you) then a bit of wire isn't going to cost them much as long as you are willing run the cable. In my own experience at home, wifi extenders and homeplugs do cause latency - massively reducing end user experience. Sending a tweet takes no bandwidth at all, but adding 35ms internally to every packet can soon add up to a frustrating experience. Unifi standards work really well for general web browsing, and will support a surprising amount of devices. You don't have to run the controller software all the time (but I like to at home on a raspberry pi) but if you do it allows you a captive portal and 'insights' into connected devices. I managed to get my unifi standards for just over £50 a piece (inc VAT) and a raspberry pi for just under £30. With some wire and a plug adapter to plug them all into next to your switch you'd be looking at ~£200 for a three AP solution or ~£250 for four. Running the controller software on a machine you've already got will save you £50 I'd guess, but unless it's running for another reason the electricity can soon add up.

Have you seen the free sophos android AV app? I believe it is one of the few that has been built from the ground up for Android, and not a ported engine from another platform. Might be marketing blurb though! I think it has a fairly quick and easy way of auditing permissions in apps too - which may be of interest.

iPhone 6 - Three Sim Only. 2GB, 200 minutes, unlimited text (plus they chucked in 3000 3-2-3 minutes which is handy as the whole family is on three) for £10. Includes tethering. Feel at home a fantastic (but so far under used) additional benefit.

I doubt there is any school or college that has 'unfiltered' internet. At the very least ISPs are likely to block the IWF list of really horrible stuff and are likely to insist on a minimum additional level of protection. After which, there are degrees of filtering. Filtering should be age appropriate but will also depend on the schools willingness to monitor and educate. After years of being with providers who did little monitoring, but blocked anything even remotely questionable many schools are now increasing their staff and student knowledge of good internet etiquette, how to spot dangers, and who to speak to if there is a problem. Monitoring is increasing, where filtering is becoming less strict. The latest Ofsted guidance reflects this trend and recognizes that it generally provides better levels of safeguarding and allows students to achieve more. The other thing to consider here is that Ofsted also want to see evidence of where eSafeguarding matters go beyond the school gate. How does the school educate and prepare parents and learners in their own home for a safe internet experience. Monitoring the internet is far more important than over blocking. Partly to ensure students are on track, but much more importantly to ensure the school can intervene if there is a safeguarding or child protection concern. Karl Rivers wrote an interesting blog a little while ago with some thoughts on his findings in schools in Denmark who take a very different approach.

As do the left and right buttons on the tweets - although as Dave said, still work to be done.

Winning comment - I should have noticed that one!

Some honest feedback. Simple and straight forward - a clean feel. Sensible segregation of areas and pages into menus. Nothing which takes too many clicks. I know it is temporary, but personally I dislike popups - especially those that take over the whole page. Menus on mobile a little clunky - I have had to attempt to open the services menu three times on my iPhone before it expanded rather than just take me to your services page. Personally I like a few tweets on the home page, but if your plugin can, I'd try and resolve the real URLs rather than the t.co ones. Although I'm having this same trouble at the moment, so who am I to criticize. You might want to retire the come and see us as Bett post? Any developments to come - online support ticket tracking, service status page... etc. etc?

Anything to suggest particular ports are very busy, perhaps there is an alert section - any errors springing up (remember dates and times are probably completely wrong). Not knowing which netgear switches you've got it is hard to say - are they all netgear? I haven't really used netgear switches for a while I'm afraid.

Now DNS seems to be working a bit better, start again with the wireless devices - are they getting valid dhcp leases, can they ping servers and other clients (via DNS name and IP). What are ping times like? I'd want to be sure my wired network was working efficiently - look at getting access to the switches. Because most of your clients seem to be wireless it's easy to assume it's a wireless issue - but it isn't forced to be.

It will take the lease to renew I believe. If you manually force a few devices to renew, you should start seeing the corresponding dns records.

That looks better. Are records being created within those zones if devices are getting IPs in those ranges? Ipcofig /release, ipconfig /renew a few of them.

Ok well the apple remote desktop stuff may well be a red herring then - especially if the machine you are using is using it. To add a reverse lookup zone simply right click on Reverse Lookup Zones, New Zone, Primary Zone, Replicate to All DNS servers in the domain, IPv4 and then input the first three octets of your IP (ie. 10.157.5), default file name is fine, then allow dynamic updates (this might be why the pen was showing on some of your devices in DHCP). Then follow the same for 10.157.6.x and 10.157.7.x Again - this might not be your issue, but should really be set with this amount of devices. I think next, you need to get into a switch. Look at DHCP is there a device with the mac address ending 79:7a:75 - looking at wireshark, that is probably one of your netgear switches. If you can't find a IP to access your switches, can you use console to set an IP? Look at ports that are very busy - what is connected to them. You might be able to setup a mirror port, that will give you loads more info in your wireshark output which might help diagnose. If thats difficult, wireshark on your server might show up more issues than running it on a workstation on a switched network.

Are there no further folders under the reverse look Zone folder in DNS ie. 5.157.10.in-addr.arpa? If not perhaps your devices are struggling to reverse lookup other devices on IPs in the 10.157.5.x, 10.157.6.x and 10.157.7.x range? As your devices is increasing that could cause additional traffic over your network. The wireshark screen grab you posted suggested a reasonable amount of UDP 3283 traffic which I had to look up... Port 3283 (tcp/udp) :: SpeedGuide Are you using Apple remote desktop heavily? I'm afraid this is one of those issues that often takes a while to pin point the culprit.

The formatting is right - but does the data look correct? Is your server on 10.157.4.1 named correctly for example. Is the record for the workstation you are using correct? Does anything seem old and stale?

Under that folder is there any mention of your IP ranges (in reverse)? 4.x.x.in-addr.arpa, 5.x.x.in-addr.arpa, etc? If you click on 4.x.x.in-addr.arpa, can you see your servers mentioned in the right hand pane? Have you tried running an internal test on your DNS server? Right click on the DNS server and click properties - then click the Monitoring tab. Try a simple test first, then try a recursive as well. do they both pass? Out of interest - does your internal domain name end in .local ?

Ok so your subnet is set to 255.255.252.0 right? The pen icon next to your DHCP scope suggests that DHCP has issued the lease, but it is also set to write this back to DNS - and it's not able to. That suggests that DHCP is set to "Automatically update DHCP client information in DNS" but you either haven't got a reverse look up zone set, or for some reason the server can't adjust the record. This could be part of your problem - but it might not. Have you got a reverse DNS zone setup? With a range of addresses amounting to over 1000 IPs, it is probably best to have one. As long as DHCP isn't serving addresses it shouldn't DHCP sounds ok. Grab Wireshark portable if you are having trouble and open it on a PC (probably much easier if you have a windows machine to hand). It runs out of a folder but does need to install one thing. Capture your (wired might be best to start with) nic traffic and ask about the type of packets you're seeing most. If there are lots and lots of broadcast 'whose got x please tell y' then we're starting to narrow things down a bit. Is x or y nearly always the same address? Narrowing down further... I'd be looking closer at DNS personally.

You said in your first post that you'd checked DHCP and you had 'plenty of addresses'. Have you double checked that the subnet is set correctly on your DHCP scope? Have you any wired devices, and are they seeing any issues? Can you ping your AD servers IP or the routers IP on a wired machine? On a troublesome wireless machine, what IP info are you actually getting? How does this correspond to what you think should be set? Can you ping your AD server IP and the router IP on a wireless machine? Looking at your switches GUI, are you seeing any high load on any ports? Could there be a loop or a faulty device causing lots of traffic? Does DNS look correct - can the machines resolve the domain, can they resolve the servers? Have you fired up Wireshark - what type of traffic is actually creating the most packets in the list - where is it coming from? It could well be an issue with bonjour - or that could be a red herring. Start simple and work upwards.

I find the dude is better when you manually create the diagram - once set up it is very useful indeed. Perhaps not the click and go solution you were after though.

I too asked and got much the same response as @grant_girdwood. Something's on its way, but they can't tell us any more. I did tweet one of the Google bigwigs some time ago asking if YouTube videos embedded into google classroom courses could be automatically approved in YouTube for schools. He thought the idea was great and thanked me for it... Hopefully the products will better integrate with each other before too long.
