CHiLL

Not the HP ProBook 450 G8/G9. Replacing the keyboard requires the whole laptop to be entirely disassembled. Like entirely. I wish there was a way to lock the interchangeable modules, as I can just see them being stolen in no time.

We have had an incident with emails and tasked with deleting not only the specific emails from all student mailboxes, but also any other email chains that it was forwarded to or used to create a new email chain. We have created a search in the Compliance Centre and it returns all the emails we want to delete. We have also been given these commands by Microsoft, to be run in this specific order: 1. Set-Mailbox -Identity "[email protected]" -SingleItemRecoveryEnabled $false 2. For($i=1;$i -lt 100;$i++){do{New-ComplianceSearchAction -SearchName gym -Purge -PurgeType HardDelete -Confirm:$false -Force;Sleep 2}While($i -ge 100)} 3. Start-ManagedFolderAssistant -Identity "[email protected]" -FullCrawl However, we are having issues with errors being thrown: Write-ErrorMessage : |Microsoft.Exchange.Configuration.Tasks.ThrowTerminatingErrorException|Unable to execute the task. Reason: Compliance search initialization for "gym_Purge" failed with exception: Your request can't be started because the maximum number of jobs for your organization are currently running.

However, due the sheer amount we are trying to delete this time, we think we are being rate limited and it's failing. Has anyone successfully deleted a lot of emails from a lot of mailboxes? If so, how did you do it?

But is that a per client connection limit or multiple clients? If I have a WiFi 7 AP and 20x WiFi 7 laptops, pulling files from the network - surely a 1Gb uplink is going to become the biggest bottleneck and it'll perform no different than the same 20x laptops connecting to a WiFi 5 AP with the same 1Gb uplink?

Maybe my understanding is wrong and I get all that MLO stuff, which is great if you're communicating with something else immediately directly connected to that AP. But as soon as your clients want to pull data from elsewhere on the network, they're all traversing that 1Gb link and bottlenecking. Is a 1Gb link enough for multiple clients on an increasing network and cloud based storage?

Is there any point in upgrading from WiFi 5 until you replace each APs network connection with 2.5Gb or greater (which includes replacement/additional switches)?

Turns out we did indeed have a loop on our network and removing it stopped all the multicast warnings that were appearing on every switch. I remember previously using a free version of HP IMC network monitor (like 10-15 years ago), but it's not been free for a long time. Spiceworks once also did an on-site hosted platorm that you just added your SNMP targets and it gave you an overview and alerts. I have tried PRTG and Zabbix, but I found them extremely complicated to set up and eventually gave up as we had other things on the go at the time. Are there any other decent free solutions? Thanks, I'll have a look at that next week, when nobody is in.

We already had Impero to remote and monitor all computers and laptops on-site and found that it also worked when we implemented our VPN. When users are connected remotely via the VPN, we can see and control their machines. We also have Meraki's free MDM, which includes a basic remote control client and use it as a fallback if Impero isn't working. As for UAC prompts, standard remote control via Impero won't show the prompts - but if you switch to Share Control, you will see them.

I'm trying to look at that now, but being pulled from pillar to post, you know how it is. I have noticed that the core switch clock is an hour ahead, as the log times were out compared to the other switches. While it might not have a direct effect, it's worth fixing. SNTP is set to our DCs, which are the correct time, Time Zone is set to "60" and DST on the is set to "Western-Europe". I wonder if setting Time Zone to 0 would bring it to the correct time and if so, would it adjust when we change to BST?

Our core config shows that VRRP is disabled. Since I don't know what VRRP is or what effects changing that setting would do, I'll not be doing it during term time at least. If all our workstations are on the same VLAN, would that cause an issue regarding Impero broadcasts? I presume Impero broadcasts work just like network broadcasts in that way, right? I'm not actually sure. We have spanning tree enabled on each switch, so that would trap broadcast traffic to only the switch the clients are connected to?

That error has been an issue in DelProf2 for a very long time, since Windows 8 and the introduction of the Microsoft Store and Apps I believe and DelProf2 hasn't been updating in quite a number of years. It is fine to ignore it as the rest of the profile is deleted as expected. Just be aware that DelProf2 doesn't work when using /d switch to only delete after x amount of days, as Microsoft changed the way that the modified dates are read.

I don't think it's specifically either the printer (Xerox C405 with 1Gb) or the laptop, as swapping the ports around still produced the error and I'm seeing the same logs on other switches. Thanks for the tip on Ruckus, though sadly we're out of support with them and aren't eligible for updates (or support if I force an update and brick it).

I'll do some more digging. Thanks for clarifying the STP, I wasn't aware that was the behaviour and you've saved me chasing my tail! The MAC address displayed is that of the Core Switch, which is somewhat concerning.

With our core network being relatively stable over the years, it's very rare that we have to diagnose potentially network related issues. We have had a relatively large number of reports that either the network is very slow or things aren't connecting. This can range from two PCs, connected to two different switches in different buildings are auto-negotiating 10MB or 100MB, not 1GB (or just say there detecting and then saying no network connected), reports that file transfers are incredibly slow, despite the file servers and storage devices looking perfectly healthy, issues with wireless clients dropping off or getting very slow download speeds and probably more that I can't remember off the top of my head. We are a HP ProCurve (5406zl core and 2530 edges and the odd Aruba CX6000) house with a Ruckus ZD1200 controller and Ruckus R500 APs. Short of going into each switch individually and checking the event log (which isn't the easiest to read), is there an easy way to diagnose where network issues are coming from?

Our A-E ports are our fibre links to our edge switches, though I don't know if these broadcast messages are related to the use of Impero, though it could be related to spanning tree.

I don't know how RAM allocation works on Hyper-V, but on VMware, I don't specify how much the hosts uses (or it's already accounted for). So I just set my subsequent VMs to have x amount of RAM available to them. According to Altaro, 2GB is enough for the host OS and the rest to be allocated to VMs: However, that's not something I can verify.

I agree with @3s-gtech, it's probably SQL eating all your RAM. Ideally, the hypervisor machine should only be doing that and nothing else, with all other requirements being on other VMs. (I'm sure I also read that they shouldn't even be domain joined for security reasons, though that's not related to this post) While we use VMware, our VEEAM server is a VM and we have it backing up all our VMs. IIRC, our license doesn't allow us to backup bare metal servers...but we have the free community edition (with SQL Express) installed on another VM to target those bare metal servers or workstations.

I had to go through our storage a while ago and convert a lot of video. For easiness sake, we use iPads or the odd old video camera to record, but the default file format, especially for the latter is not efficient. I ended up using WizTree to locate all the .MOV iPad files and .MTS video camera files and using handbrake to convert them into a H265 MP4. My PC has an Intel Arc A380 and I had best performance from the H265 Intel QSV preset. I also set the destination location to be the same as the source location, so the new file would end up in the same place. However, it was a time consuming process because I had to do a quick check with each file that the conversion had worked before deleting the original video. On average, I had file sizes that were some 15-25% of the original .MOV files and about 10% of the original .MTS files, saving about 400GB on our storage server. We are starting to move a lot to SharePoint for storage and as long as they copy them onto there, I don't really mind the file sizes - it's only an issue if we break 40TB+ on our SharePoint/M365 local backup...which given we're on <10TB for absolutely everything up until now, I think we should be fine.

In fairness, NI probably falls under the "Bromcom MIS Cloud UK". I am also not surprised that the UK has the most downtime, as I presume it's by far the most busy of all of the other cloud instances.

We had a demo of Senso Cloud within the past couple of years and also experienced this sort of thing. We liked the idea of it being serverless on our end, but it was inconsistent with commands, WOL, broadcasts, etc, not hitting all machines selected, despite them being on and online. We decided to stay with our on-site Impero...while certainly not perfect, it's more reliable in those ways.

Basically all the points raised previously. I don't have the time to deal with pressure sales, repeated calls for clarification, etc. Here's what I need and you give your pricing and ETA. If you can't source it (or on a timely manner) or your pricing is too high, fine, you tried, we aren't going to hold that against you - just say so and we'll do business again another time. They should know their market, most of us don't have much money to spend, so we're only contacting you when we know what we want to achieve. I think I just involuntarily twitched, just thinking about an ink/toner/printer sales person who does not understand that, despite knowing we are on a multi-year managed printer contract with another company for 95% of our printers. We were getting calls at least once a week and we'd told them not to call unless we ask, but they still do. It got to the point where our receptionists knew them by voice knew not to even attempt to put them through to us and we ended up having to contact their manager who had to have a word with them. They still try about once a month, but for those printers we have that aren't managed, I'm using a different supplier anyway.

Reminds me of the technician in the secondary school I attended, though he was a sole technician. The "office" was literally a cupboard with servers in it, just deep enough to fit a shelve for a monitor and some floor tower servers. If the door was open, he had to stand up and use a folding chair when inside with the door closed.

I drink a lot of tea, but I'm lucky that for the past 9+ years in this school, our office has been two doors down from the staff room which has a water boiler. We did have to resort to buying an under-counter fridge though, as even though the staff room is so close and has a fridge - our school doesn't provide tea/coffee/milk/sugar and anything in the fridges there are often stolen or used without permission. Instead we opted to get a second hand fridge from eBay (we made sure it passed a PAT before using it!) and store our milk and lunch here. A previous school I worked at had a similar setup, though due to the inconvenient distance to the staffroom, they used a large 5L water dispenser bottle and refilled it as necessary.

For organisation, we bought ourselves a couple of these Gratnells shelving units and trays, so we can organise our cables and other regularly used items: [ATTACH=CONFIG]70754[/ATTACH] Our office is very small, so storage and organisation became a priority. We keep a small selection of larger items, like monitors, projectors, laptops, desktops, etc, for quick access if we need any. The rest of the larger or infrequently used items live in our storage room, on the other side of the building. Because power sockets were limited, I pulled out a couple of 10-gang extension leads from an old iPad/laptop trolley that was being disposed of and screwed them into the wall by my desk for easy access (I just have to be conscious about the amount of power I'm drawing through the one wall socket it's plugged in to).

I have figured out how to reattach the keys, assuming there's no damage or spare parts are available. Due to the brittleness of the materials, there's a few places of failure that can occur and I've tried to address them in the guide I created (for when I inevitably have to do this again in the future and have forgotten). If anyone wants the guide, it is as follows: Fig 1: [ATTACH=CONFIG]70740[/ATTACH] Fig 2: [ATTACH=CONFIG]70741[/ATTACH] Fig 3: [ATTACH=CONFIG]70742[/ATTACH] Fig 4: [ATTACH=CONFIG]70743[/ATTACH] Fig 5: [ATTACH=CONFIG]70744[/ATTACH] Fig 6: [ATTACH=CONFIG]70745[/ATTACH]

Thanks for that, though unfortunately, I cannot get them to stay down. Once the scissor mechanism is in place and I put the cap back on, I do sometimes get a click as I'm pushing, but it's evident that the top of the cap is lifted. Two or three key presses later, then the whole cap comes off again. I don't know if this is a common issue with these G8s or I've come across two faulty keyboards in as many months.

We have a number of HP ProBook 450 G8 laptops and we've now had two laptops where the users have reported the keys have just popped off. With the first laptop, the T key came off, but had broken clips, so wouldn't stay on. We opted to replace the keyboard (something like £120) and it's not a small job - you pretty much have to disassemble the entire laptop to replace the keyboard, as it's the entire top shell. Now we've had another instance, but the key clips look intact. I am loathed to repeat the process of purchasing and replacing the entire keyboard, because it seems like a waste of money and a whole load of time. This leads me onto my main question - when these flat style laptop keyboard keys pop off and look intact - how on earth do you reattach them? It's something that has evaded me my entire career and I've never truly had to investigate or had the will power to look into it separately.
