In my experience, what you've described sounds like either a dead processor or motherboard (or both), usually caused by a faulty PSU/short circuit/power surge. In this case, I hope for your sake I'm wrong. Good luck If you have a spare processor you can try, that may work for you.

Installing Adobe and Java across network
Sephiroth replied to marsdenprimary's topic in Windows Server 2008 R2
Not sure if it was fluke, but I've managed to get all of the relevant MSIs downloaded by using different browsers! PPAPI from IE; NPAPI from Chrome and Active-X from Firefox. What a faf...- 16 replies

That was one of the reasons we went with the midspans that we did; full control of each port.
-
Yeah, it is a bit steep... We got those as an alternative to replacing all of our switching with PoE when we had our new APs and telephony. That saved us around £20k so was justified to go with the more expensive midspan. If it's only for those bits I do recommend the 8+2 port Netgear switches. That is almost exactly what we bought ours for, with the added bonus that they are silent, unlike most standard switches.

We have 10 of these: https://www.comms-express.com/products/high-power-24-port-full-power-36w-per-port-managed-gigabit-poe-midspan-dc-and-ac-input/ they're fully managed over the network, and have been running faultlessly for the last 3 years with no hiccups at all. Admittedly we didn't pay that much for them, though I can't remember exactly what we did pay. We also have 4 of these, I can confirm that they are good switches and are easily managed. the interface is very slow on them though and they don't have a full CLI (that you can get to, anyway)

I'm having the same issue here. I can get the NPAPI for Firefox, but can't get the PPAPI or Active-X versions. clicking on the links does nothing.- 16 replies

EduGeek Minecraft - HermitPack Server details
Sephiroth replied to localzuk's topic in EduGeek Minecraft
I'm having issues with this pack, both single player and on the server. I've no idea why, but I get 1-5 FPS whilst standing still with all settings at their lowest. Vanilla 1.10 works fine at ~300 FPS. I've updated my graphics drivers, played with the java settings, killed everything that isn't necessary... Has anyone come across this already? PC Specs: L5520 Xeon quad core processor 12GB DDR3 RAM ATI Radeon 6870 GPU -

IIRC, villagers are dependent on the number of doors, not structures. so as long as our houses have doors, they should be alright I'm not sure how they handle doors from mods though... -

I would imagine a large coal plant would look good. we could even make it run on coal (charcoal)! -
Have a look at APR Telecoms. We've not made the switchover yet, but they provided and support our IPCortex phone system. We got comparative quotes in from several suppliers and APR were by far cheapest for us. I'll see if I can get some more info when I get into work.

I downloaded last night but didn't join... Forgive a n00b question, but how do you install client-side mods? I've got the waila mod but now have no idea how to get it to work. -

Support companies for your school's IT - Quick poll
Sephiroth replied to nikaso's topic in General Chat
We have a fully managed service for our Macs (integrated with Windows AD Domain), and we get SIMS support from our LA. Almost everything else is done in house, though we're looking at getting a support contract for anything high level taht we don't have time to deal with or fault find (e.g. file server failure; VM cluster/ backup repairs...). We're a team of 3.5 (IT Manager [FT], Network Tech [FT] and 2 IT/Expressive Arts Techs [FT, TTO]) in a school of 2000 students. -
@pcstru I have something similar here. 3 scripts and a DB to do it, but works for me. All automated and runs every night. Most of the time, students have their accounts before the staff know they exist (or I do, for that matter!). I have a script to pull house, year, form, admission (used for their username, so all are unique by design), SIMS UPN, and name from sims (as well as generating a temporary password and working out what the year of entry would be if they joined at year 7) into my own database table; I pull student class codes and subjects, listed per student, into a table; I pull all staff name, code, subject (main where applicable) and role into a table; and I pull all generated student groups (with appropriate prefixes) into a table. Each row is flagged 'modified' if there's been a change to the record. I then have a script that reads from that and checks for the modified flag or active flag and updates or creates as necessary. It sets up the home directory including quotas and file screens, along with all the group mappings and filling in AD fields. I have a 3rd script which creates Exchange contacts for each student, put's the contact in the correct groups so that they are put into the correct address lists and contact groups, then collates all information into emails to relevant people (1 per staff member, regardless of number joining a class) and emails me a full log (also stored in the DB).

I tend to use Sketchup for this. Perhaps not the simplest method, but gives nice and accurate designs.

Viewing Students Passwords Without Changing Them
Sephiroth replied to Brad_Sarge's topic in How do you do....it?
Would resetting the password not stop them getting to the mailbox anyway? -
Click Start, type regedit in the Start Search box, and then press ENTER. If you are prompted for an administrator password or for a confirmation, type the password, or click Continue. Locate the following registry subkey, and then right-click it: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\CSC Point to New, and then click Key. Type Parameters in the box. Right-click Parameters, point to New, and then click DWORD (32-bit)Value. Type FormatDatabase, and then press ENTER. Right-click FormatDatabase, and then click Modify. In the Value data box, type 1, and then click OK. Exit Registry Editor, and then restart the computer. Source KB942974 Note that any files not synced to the network will be lost if you do this.

PowerShell HELP - Need to change just server name in home folder path
Sephiroth replied to MuttsNutts's topic in Scripts
I'm assuming that the space in "$oldS erverName" is not intentional? If you take that out it should run, I believe. -
This is the Routing table from my core: The "Learned Routes" at the bottom are the VLANs subnets and the "Next Hop Address" is the router's address and the gateway for the subnet. I have static routes for any traffic that goes to our other site, which you can ignore, but also in the "Static Routes" tab, at the top, is the default route, which means; anything that the router doesn't know about goes to this address (in my case, the firewall/gateway). Once you've added the addresses to the VLANs here: they are automatically added to the Learned Routes table (above). The routing table is what tells the router where everything is. As it knows where all the subnets are and what the IP ranges are for each, it knows that for a client on VLAN 170 sending packets to the servers on VLAN 10, the packets need to be routed between the 2 subnets. As far as internet access is concerned, What happens is that your device sends a packet request for a website address to it's gateway, the router. the router doesn't know where that address is, so it passes the request to it's default route, the upstream gateway. This process is the same, regardless of which subnet tthe request came from.

I have no experience with doing it this way, though should also work if preferred. Either way I would use a Layer 3 switch rather than a dedicated router. I have a full Netgear environment with M7300 24 port fibre core and M5300 edge switching in each cab. If you need advice with config just ask.
-
Sorry, I missed the "Brand new school" bit If you have no core switch, I would get a device to use as a router (another Netgear switch with layer 3 licence would be ideal. We have an M7300 fibre switch, though that may be overkill for a primary. an M5300 or if you have the money and foresee expansion in the future, an M7100) and configure that to be the default gateway of each subnet. Then it's default gateway becomes then next upstream router (192.168.40.1 in your example). This will connect to all edge switches (and ideally no edge switches will be connected together). Once you've got routing set up properly, VLANs can be created on the router and given an IP address on the router. This will be the routers address on that subnet and therefore the gateway for that subnet. then you'll need add the VLANs to each of your edge switches with the uplinks (at both core and edge) tagged on every VLAN being used. The client's gateway will be the router's address within their subnet. With this set up all packets will go to the router for it to pass to the next hop. For internal traffic, that will be direct to wherever it's destined for and externally it'll be the upstream router. For clarity: -Untagged packets into the network from a client will be tagged by the switch with the VLAN set by the PVID of that port -Untagged packets out of the network to a client will gave any VLAN tag stripped from the packet -Tagged packets will pass through any port that is tagged for the VLAN in the packet -A port can have a multiple VLANs tagged but only 1 untagged (though it can have tagged and an untagged at the same time; e.g. if you have phones with network passthrough that support VLAN tagging, you can set the port on the switch to be tagged on VOIP[10] and untagged on Default[1])

what are you using for your internal routing at the moment?

I would recommend Counterpoint for Macs. We use them for everything beyond 1st line as we don't have anyone in-house with the skill set. They do everything from software updates to full suite imaging to sever set-up. They also joined our Mac server (dustbin) to our AD domain and set up backups. If anyone wants a contact, drop me a PM. We used to use XMA for our project works. Their support and communication has been dire since they were bought out by Viglen. We waited for 2 months for a response to a request for a scheme of works for a major project, to be told that the engineer that we'd been talking to (and that had done most of the works on our site before now and knew the infrastructure intimately) had been reassigned without us being told. That engineer was the only thing keeping us with the company. For cabling I would recommend Advantage Technologies, whom have cabled the entirety of one of our buildings for AV and projection (projector, speakers, amp, breakout box, cable kit, whiteboard). We also got them to re-cable a large amount of the building, including moving a cabinet out of an office and re-terminating everything in it. They are a little more expensive than some but their work is very good.

There are a few ways around this. As @JonThompson said, scripts are good to clean up at the end of deployment or for those irritating applications that don't work otherwise. To silently install applications varies... Best is with an MSI, either provided or extracted from an EXE. If you can't get an MSI, most EXEs have a silent switch you can use. There's a website that I use to find what packager was used and what the switches are. I'll find it and post tomorrow when I'm at work. If none of that works, then AutoIT is a very useful tool to script navigation through a GUI. I've had to resort to this a few times to get things installing properly. A well set up MDT system can be nearly zero-touch if you set up the database. I'd never go back to thick imaging again now! It's saved us loads of time, even when preparing an app can take 10 times as long as just doing it manually. Best of luck to you.
