Start of the struggles here.

Update 1:
1) I was able to make audio work.
So "Multimedia Audio Controller" disappeared from this list:


2) I installed bluetooth drivers (looks successful, but I did not test if it actually works).

3) I was NOT able to make wireless network adapter work.
I successfully installed Intel® Wireless Adapter Driver for Intel® NUC Kits NUC7i[x]BN from Intel® NUC Kit NUC7i3BNH.

4) I updated NUC's chipset device software.

5) When rebooting after installing Windows Server updates ("Cumulative Update for Windows Server 2016 for x64-based Systems (KB4015438).") -- NUC is showing "We couldn't complete the updates. Undoing changes" message.
Then after couple of reboots that cumulative update is gone, but suggests to install itself again.

So, overall impression of "Windows Server 2016 on NUC7i3BNH" is poor.
I do not really want to spend too much time on troubleshooting these silly issues, introduced by greedy sales managers.

I do not really want to work with Windows 10 either, so I consider returning this NUC7i3BNH and possibly buying "older" and more expensive NUC version: NUC6i7KYK ("NUC Skull") because NUC Skull does officially support Windows Server OS.

What would you recommend me to do?


Update 2: rezkiy and yatur suggested ulterior motives to explain Intel's decision to not support Windows Server for most of their NUCs. The overall direction of these explanations seem right, but some details seem to be missing.
What do you think?

I bought NUC7i3BNH.
Then I tried to install Windows Server 2016 Standard on that NUC.
Windows Server installation itself was successful, but several drivers, including Network Adapters(!) and "Multimedia Audio Controller" - did not install.

Search for drivers brought me to:
http://www.intel.com/content/www/us/en/support/boards-and-kits/intel-nuc-boards/000005628.html
where to my amazement I discovered that most of NUCs do NOT support Windows Server OS.

Further research pointed me to a hack that allows to manually use Windows 10 drivers on Windows Server 2016.
It goes like this:
1) Open C:\install\LAN_Server2016_64_22\PRO1000\Winx64\NDIS65\e1d65x64.inf
2) From this section:
[Intel.NTamd64.10.0.1]

copy these 3 lines:
===
%E15D8NC.DeviceDesc% = E15D8.10.0.1, PCI\VEN_8086&DEV_15D8
%E15D8NC.DeviceDesc% = E15D8.10.0.1, PCI\VEN_8086&DEV_15D8&SUBSYS_00008086
%E15D8NC.DeviceDesc% = E15D8.10.0.1, PCI\VEN_8086&DEV_15D8&SUBSYS_00011179
===

into this section:
[Intel.NTamd64.10.0]

3) Then turn off drivers checks:
bcdedit /set LOADOPTIONS DISABLE_INTEGRITY_CHECKS
bcdedit /set TESTSIGNING OFF
bcdedit /set NOINTEGRITYCHECKS ON

4) And finally install the driver:
pnputil.exe -i -a C:\install\LAN_Server2016_64_22\PRO1000\Winx64\NDIS65\e1d65x64.inf

After that Network (and Internet) started working on my new NUC.


But I do not understand - why Intel does not allow these drivers under Windows Server 2016 by default?

Update: Windows Server 2016 on NUC7i3BNH struggles - part 2.

We tried to run PowerShell remotely (in order to automate build deployment).
We managed to make it work on developers' machines, but on production server it just refuses to work:

Note "Unable to check the status of the firewall." part of the message.
Why would Enable-PSRemoting command try to check the status of the firewall?

Another Windows WTF reported by yatur


Update
Finally we were able to fix this remote powershell issue.
The problem was in Group Policy for IpV4Filter on our production machine.
IpV4Filter was limited to a single IP address (main address of that production machine).
I have no idea why it was setup that way.

This is how I fixed WinRM localhost access problem:
Run gpedit.msc
Local Computer Policy
Computer Configuration
Administrative Templates
Windows Components
Windows Remote Management (WinRM)
WinRM Service
Allow remote server management through WinRM

In "IPv4 filter:" change "208.43.198.72" to "*":
IPv4 filter: *

In the end, PowerShell and Microsoft server tools leave a negative impression due to bugs and pathetic diagnostic.

Consider another PowerShell surprise:
"ls" and "dir" commands produce empty output in case when folder is empty. No headers, no message that says there are no files. Just nothing. WTF?

After several months of observations the performance of ElasticSearch instances I reported ElasticSearch memory leaks issue.

The issue was prominently closed without any resolution.

I guess now I have to just restart my ElasticSearch server every few days in order to "patch" these memory leaks.
dennisgorelik: (2009)
We moved our ElasticSearch job percolation functionality from Windows server to ElasticSearch cluster on two Linux VPS-es (3GB RAM + 2GB RAM).
Percolation performance improved at a fraction of hosting price (relative to price of dedicated Windows server).
The most important benefit is that we can increase percolation performance just by adding more nodes to our ElasticSearch cluster.
Performance of individual percolation query on ElasticSearch cluster is about the same as on single node, but adding more nodes to ES cluster allows to execute more queries in parallel.
From our experimentation we determined that optimal number of percolation queues on 2-node cluster (2 CPU cores on each node) is ... drum-roll ... 4 (1 for each CPU core).

That configuration allows us to percolate up to 216 jobs per minute.

Q: What is ElasticSearch percolation?
You may create a job search alert.
PostJobFree will put your alert alongside with 160K+ other users' job alerts into ElasticSearch job percolation index.
Then every time when we get a new job - we percolate that job against 160K records in job percolation.
If job matches your (or anyone else's) job alert, then ElasticSearch percolator returns IDs or all these alerts, so we know to send you email about new match.

Q: Why host ElasticSearch on Linux?
Windows version of ElasticSearch does not support mlockall setting. That means there is no good way to prevent ElasticSearch from using swap-file.

I'm trying to create USD boot device (from my USD thumb drive) in case if my primary SSD goes dark.
Here's the instruction how to create it:
http://www.thomas-krenn.com/en/wiki/Creating_Windows_UEFI_Boot-Stick_in_Windows

I did.
Then booted from my thumb drive.
It asked to install Windows.
But installer is unwilling to install Windows 7 on USB stick.
The only installation options are other disks on my computer.

Is it supposed to be that way?
