@adam-ierymenko I'm guessing the laptop was off two+ days. The user only uses it two days a week at most.

I'll consider changing it when I move to the flat network...

You are not on a flat network? That is how it works. You can have as many DHCP servers as you want as long as they do not see each other.

No, I have several subnets. The networks see each other through a router.

I'm not sure what you mean that you can have many DHCP servers as long as they don't see each other?

In my current setup, at this branch location of 10 PC's and 16 phones I have two DHCP servers. Each provide IPs for a different range in the same subnet. The Mitel PBX has a DHCP server but only responds to Mac addresses belonging to Mitel phones. The windows DHCP will respond to everything. My question was - what happens if the Windows server responds to a phone faster than the Mitel DHCP server? I'm guessing the phone wouldn't work.

This branch will probably always be on a different subnet (local to that location), but my main office has 5 /24 subnets.. I'd like to move them to one /22 subnet.

I need a series of "how I hear it" marketing interpretations but here is one that I like:

Marketing: 9 out of 10 dentists recommend toothpaste X.

What I Hear: Likely 90% of dentists say it doesn't matter what you use as long as you use something, 10% say definitely don't use toothpaste X.

Saw this today and thought of this thread...

OK, I guess I could try and test it if I have the time soon 😉

Did you get a chance to test?

I am lost on this one too.

The Battery is draining fast after some google application update. Please share if any one also facing same problem.

That's not very good. Google's own apps should have the best chance at being good about battery life issues.

Those little Atom processors that they tend to use (I miss the Sparc32 days, it was just more interesting) use very little electrical power and produce very little heat and tend to last for forever. Pretty much unbeatable.

Unfortunately no. We at @ntg used to provide leasing for Upstate NY but have gotten away from that, too much complication without enough benefit. We have never leased gear ourselves, especially internationally.

@chrislaz8592 did you get this working or do you need additional assistance?

So you could use something like WinSCP to connect to Amazon S3 service of yours assuming its configured as NFS / SMB Share and copy down or upload your file(s).

No, there are a couple things wrong here.

NFS / SMB are network file systems, not block storage. So this goes against what you posted in the line about about using whatever filesystem you want which means block storage. Neither block storage nor network file storage is an option on any of these products. Nor would you want it as even NFS is horribly weak over a WAN link and SMB is far worse.

WinSCP is a tool for SFTP, FTPS, SCP and FTP usage, not SMB or NFS. So that isn't the right tool in any circumstance here.

The biggest reasons for always virtualizing are around hardware abstraction and free. Virtualization is free and easy, which is important as it takes away the "why not virtualize" caveats. Virtualization has, effectively, no downsides. It actually lowers the cost and effort of systems administration and through the miracles of abstraction it actually makes the overall system simpler, rather than more complex!

The hardware abstraction aspect is critical because it makes our systems more stable, rather than less stable, and more flexible for whatever we might need in the future. It reduces technical debt with no real cost of its own. These aspects mean equal or lower cost with lower risk.

It's these aspects, the "always pros" and the "lack of cons" that puts virtualization into the solid "always category.

Blades seem to make you give up a lot of flexibility. With an old fashioned server I can run them diskless today and add disks tomorrow if the way that I want to use them changes. But if I have a blade, I'm stuck.

Best way I've heard it described is that when you enable Hyper-V on a Windows Server, your Windows Server Core (or GUI) becomes the Linux equivalent of Dom 0

And exactly like installing Xen onto Linux, Xen inserts itself as a "shim" under Linux and then reboots, booting into Xen instead of Linux. HyperV is identical, inserting itself as shim under Windows, rebooting and booting into HyperV instead of Windows.

HyperV is modeled identically after Xen.

Scott, thank you for your topic. I am planning new installation and comparing between RAID 10 and RAID 5 on ssd drives. What do you think about stripe size and TBW for two types of raid? Do you know what size of blocks will be written on disks if service (sql for example) writes 8Kb on volume. For raid10 I think it will be two 8K blocks on mirror disks. But for RAID 5 it will be two blocks with size=stripe size and may be 32 or 64K. And in raid5 configuration TBW limit will be reached faster.

I'm not Scott but in your context RAID5 seems to be preferred. Because 1) Flash and not spinning disk used so typical parity RAID issues associated with high-capacity spinners are gone (see URL below) 2) Database logs are sequential writes of a big sizes so should "touch" maximum amount of spinners possible and because of sequential nature read-modify-write is not going to happen and 3) RAID5 gives you write performance of (N-1) and RAID10 does (N/2) (where N = amount of spinners).

Good luck 🙂

One thing I think they missed is the ability to select what updates you want to do. All Windows 10 updates are forced as I have seen... I think that while many updates are great to have,... there are some I just don't want....

Like BING or Edge...

This sucks because I know one update that broke the ability for SolidWorks to do calculations. It was a non essential update, so if you have it SolidWorks pretty much was useless. Once you uninstalled it, everything was fine.

The key...if you're into functional GPO's (vs. monolithic) is having an effective and meaningful OU structure. Otherwise, half of your time will be creating security filters or specific targeting which can get very confusing very quickly.

The performance impact of processing GPO's in general is negligible, but it does depend on what that GPO is doing (i.e. deploying software in general or printers over slow links? Have a seat and grab a cup of coffee). I would be more concerned if you have slow links at your sites - if this is the case, you need to ensure that you have Sites and Services configured appropriately and a RODC at your remote site to facilitate speedy logins.

Being aware of GPO enforcement (which you should try to avoid) and LSDO ordering will help you tons.

There's really no right or wrong way to deploy GPO's as it is more about what you're doing with them, how they are deploying, and what you're deploying them to.

Personally, my preference is to break my GPO's out to functional objects - i.e. this one is for security, this one is for desktop preferences, this one is for drive mappings, etc.

Will this be a thread that escalates quickly?

I hope to keep it curtailed to just the facts - if you want to whine or better - ask for help regarding an issue/outage, please make another thread.

That makes sense. This is a FreePBX install from FreePBX ISO as far as I can tell from looking at it and all files come from the Schmooze repos and it is causing it to be very out of date compared to standard CentOS 6.

Wait, what? Does the FreePBX distro change what repos yum uses for base CentOS updates?

Yeah, it uses Schmooze repos instead of CentOS ones. I can change that, of course, but by default...

In previous versions(of MS office) and I'm stretching my memory as I haven't had to do this in a long time my self.

You could place another window right behind the presentation view and use Alt-Tab to present it.
