@scottalanmiller said in Getting DHCP BAD_ADDRESS on Windows DHCP:

Have a DHCP server that is getting something trying to register to it with a BAD_ADDRESS. Obviously, we can't just look up the MAC address and track it down, because the MAC we get is bad.

We've got one new switch that went in about the time that the issue started, but we think that that is off of the network now, and the issue continues. There are loads of new web cams on the network, but they seem to all be working fine.

Any guesses on tracking down the issue?

Any time I've ran into this issue, it was because either someone statically assigned an address which resides in the DHCP scope (rather than doing a reservation, or using a different range). The other thing I've noticed is two devices, unaware of eachother, serving DHCP requests; such as a Windows Server with a DHCP role, and a Cisco router, both doing DHCP in the same range (human error obviously).

@dustinb3403 said in Synology-Storage Manager less than File Station:

Is there something doing snapshots on this device?

No snapshots, replication, or cloud services associated. It's just a destination for Veeam jobs.

Running the latest DSM. The appliance is just a backup destination. One single volume, no LUNs, no apps doing replication or using something like Cloud Station. Pretty simple device overall.Storage Manager shows used space is 4TB, but 2 folders in File Station add up to 9TB.

Any idea how that's possible?

At about an hour a year, I would say four 9's is acceptable.

Now what I do find interesting is this is a Android device, so if you can install apps (you can) you should be able to install SfB and then you'd have SfB on the phone as well.

It would likely work as a secondary phone service though that is in no way associated with the SIP service you have. FreePBX etc

Using something like SfB on it might go beyond its intended use... using it for that would save on cost of buying Polycom, but if cost and quality was a concern then the client wouldn't use SfB at all.

Wondering if this solution is a weird little niche where Ubiquiti can just check a box that says "we offer VoIP".

Well this isn't a VoIP offering, its another device that takes advantage of the VoIP capabilities. These don't work without a phone system.

From the documentation I found, it looked like the USG would be able to control the devices; but I haven't looked into exactly what extent or if they are just devices with an Internet connection and an Android phone app.

@dustinb3403 said in Unifi VoIP:

From looking at this, you can use the Unifi controller and DHCP option 66 to configure and update these as well. What I'm seeing for the type of service though appears to be SIP only.

So I'm not sure if these would work with SfB or some other traditional style phone system.

My feeling is that you'd have to use some app like Grasshopper if you want central anything (extensions, ring groups, etc). But if you were going to use an app like Grasshopper, may as well not even use a physical handset and just use a soft phone.

But for places that are extremely tiny, need to just call out or have one person answering the phones and have Ubiquiti gear anyway, I don't see a reason not to take a look. It's just a question of if you would buy something like this or just use a soft phone at that point.

@black3dynamite said in Unifi VoIP:

$149 is considered a good deal?

Similar basic devices from places like Meraki/Cisco/Polycom are much higher than that. $149 is decent... Considering it's basically just a tablet with a handset, I can see the prices potentially coming down even further over time. Strap a $10 handset on a $50 Amazon Fire tablet and boom, Ubiquiti phone.

Anyone actually tried Unifi for VoIP? I think it's been out a couple years now but have yet to try them out.

Are there any printers installed on it?

I had server once that kept randomly crashing and it turns out it was a printer driver of all things.

No printers installed... but I had wondered the same thing as I found that on some forums.

It drove me nuts.

Kept rebooting the server in the middle of the day, randomly. It was awful.

Are you sure the spooler caused the reboot rather than a faulting driver not being isolated and caused the server to reboot because of a driver issue? I've witnessed print spoolers on servers crash many times and cause the whole list of printers to become unavailable, but that is about the extent of it.

Pretty sure it was the driver.

I think it was an older printer that maybe didn't have an updated driver.

I could definitely see a problematic driver causing a server to crash. If it isn't isolated, it could certainly cause the spooler to crash as well (but without causing the server to crash).

@bbigford said in Why is the Third World Running Windows?:

Why are they running outdated versions of Windows rather than something free... I have no idea on that.

Well, if you have a market where essentially no one knows what an OS is, or how to install one.... it's rather a leap to think that they could reasonably update. In the US everyone knows how to install an OS or their nephew does. But in much of the world, that would be an expensive, rare resource that you have no idea needs to be sought out.

Sorry, I meant to add I get that Windows carries an expense and not everyone can honestly afford to run it up to date. What I meant is if they need a platform and the end user computing device is irrelevant for that access, they could run their favorite distro of Linux and have it both fully up to date and carry no cost.

Why are they running outdated versions of Windows rather than something free... I have no idea on that. If they had more access to either up to date software or more innovation through cloud resources, that would be key for me.

By access to more innovation, allowing third world country researchers to more easily (and cheaply) access cloud computing for machine learning/AI/etc... in my opinion access at an affordable level is important.

Also found vssadmin crashing. Found a scheduled task to create a shadow copy, which conflicts with backup software installed on the server. Not sure wtf they have been thinking after cleaning up this server so far. This one is definitely going to be redone before too long.

Backups are officially healthy; completing without error.

Veeam to Synology, Synology to BackBlaze B2 or Wasabi. Works great and is cheap ($5/TB/month)

Some people I know reserve them for things like "Sent from mobile, please excuse my typos!"

After some embarrassing typos from people, I see the reasoning.

Virtual

@phlipelder said in Windows Server - AppCmd crashing:

Are all RDS (Broker/Gateway/Web/Session Host) set up on the same server?

If that is the case, make sure Broker/Gateway/Web are set up correctly and have the correct permissions set for the deployment and for the collection(s).

Obvious, but make sure the host is up to date.

Where is the RD License server? Has it been set up and activated correctly and is the Session Host working with it without error?

All the features are on the same server, and it has every feature added (I recently removed some for testing). As far as permissions, I finally saw in the advanced settings where you could specify the local account (Network Service or otherwise), and I am assuming the log file that it writes to is in c:\programdata...\WER as I can see some appcmd.exe output files in there, but I was a little unsure if I understood the permissions piece of that requirement correctly.

@dbeato said in Windows Server - AppCmd crashing:

Is there a dump file or just this application that is failing?

I tried using a couple programs that would capture a dump file. Never could get them working. I've disabled some Windows features on RD/CA stuff that were unnecessary, and backups are now completing without error. I'll report back if they keep going well through the weekend.
