  1. New/Set-NetQosPolicy -ThrottleRateActionBitsPerSecond is double buggy, vs documentation vs actual set values

    Documentation at
    https://docs.microsoft.com/en-us/powershell/module/netqos/new-netqospolicy
    says -ThrottleRateActionBitsPerSecond would enter the value as bytes per second. Example 4: 10 MB would result in limit of 80,000,000 bits per second.

    In reality this will set: ThrottleRate : 10.486 MBits/sec

    Note! Not 10 megabits per second, but 1.0486 times that, nearly 5% difference.
    This is a potentially very bad bug because limits would be set as the highest rate of traffic. Someone trying to set limits per whole available bandwidth might end up going 5% over the available bandwidth and result in network traffic congestion.

    And it makes setting actual limits a difficult exercise when…

  2. IPAM-Client benötigt sinnloserweise lokale Admin-Rechte

    Wie unter https://social.technet.microsoft.com/Forums/de-DE/c69529e0-a8de-4063-a2f0-1b2d8e180c28/windows-not-finding-ipam-client-installation?forum=windows_Serverde diskutiert benötigt der IPAM-Client im Server-Manager lokale Administrator-Rechte. Dies ist in meinen Augen unnötig und diese Abhängigkeit sollte aus Sicherheitsgründen entfernt werden.

  4. VPNAuthProtocol uses the first certificate found with matching name, should use specified certificate.

    On my VPN server, I run "set-vpnauthprotocol -rootcertificatenametoaccept $RootCACert", with $RootCACert containing the public certificate of our internal root CA. After running this command (and after restarting the server) I run get-vpnauthprotocol to confirm that the certificate was updated, but find it set to a different certificate than the one I provided. This different certificate has the same name, but all other attributes are different.

    Even though a certificate object is required for the 'rootcertificatenametoaccept' parameter, it only uses the name of the certificate provided, then searches for a certificate matching that name in the computer's local root store. If…

  6. Conservative RSS Profile assigns 2 CPUs when 1 RSS Queue is chosen

    Hi,

    I'm trying to understand how RSS works and while experimenting, I found out that when Convervative RSS Profile is used with 1 RSS Queue, Indirection Table stay the same, with two processors. Is that correct behavior?

    I'm asking, because when I choose other RSS Profile (for example Closest or ClosestStatic), number of the processors in IndirectionTable always match NumberOfRecaiveQueues.

    Is that mean that I have some bad version of Powershell/Windows/Drivers or is it correct??

    Can anyone help with that?

    I've used Set-NetAdapterRss cmdlet to set things up.

    Name : test0
    InterfaceDescription : Intel(R) Ethernet Converged Network Adapter X550-T2
    Enabled…

  8. Fix the ping timeout bug that gives incorrect "reply timed out" messages in Server 2012r2 and Windows 10 for pings under 1000ms timeout

    Ping can take a timeout, if the timeout is set less than 1000ms then genuine replies start getting ignored as timed out failures.

    Does not affect Server 2003 or 2008.

    Does affect Server 2012 r2 and Windows 10

    Appears to be a problem in WinAPI / networking stack rather than .Net or ping.exe implementation - happens at ICMPSendEcho2Ex and ICMP6SendEcho2Ex layers at least.

    Documented in detail here: https://stackoverflow.com/questions/45528336/winapi-why-does-icmpsendecho2ex-report-false-timeouts-when-timeout-is-set-belo

    and here: http://web.archive.org/web/20150519002258/http://www.frameflow.com:80/ping-utility-flaw-in-windows-api-creating-false-timeouts/

  9. DNS recursion using wrong NS for delegated zone CNAME

    When Server 2016 DNS Server has a delgation within a primary zone, CNAME records in that delegation result in queries to the delgation's name servers, not forwarders / root hints.
    For example:

    Primary zone: one.example
    Delegation: foo.one.example, with nameserver ns.bar.com

    In that delegated zone, there exists a record:

    baz.foo.one.example IN CNAME other.two.example

    two.example's zone, hosted by ns.somethingelse.com, has a record:
    other.two.example IN A 1.2.3.4

    From a client pointed at the DNS server, query baz.foo.one.example.

    I would expect the server to query ns.bar.com for baz, receive a reply of other.two.example, and then query either two.example's nameserver, or use the default forwarders…

  10. Fix Remote-NetIPAddress to work inside try/catch

    Writing a script to provision a machine - we first remove the IPAddress (and any default gateway), But sometimes there is no address. That;s fine - we just try/catch and move on, liike this:

    Try {

    Remove-NetIPAddress -InterfaceIndex $IfIndex `
    
    -AddressFamily IPv4 `
    -Confirm $false
    }

    Catch {Write-Verbose 'No IPAddresses found'}

    But instead of the nice write-verbose message, we get a fatal error:
    Remove-NetIPAddress : No matching MSFTNetIPAddress objects found by CIM query for instances of the ROOT/StandardCimv2/MSFTNetIPAddress class on the CIM server:
    SELECT * FROM MSFT_NetIPAddress WHERE ((IPAddress LIKE 'False')) AND ((InterfaceIndex = 3)) AND ((AddressFamily =…

  11. Server 2016 wifi does not work

    In Windows Server 2016 RTM, like in the TP5, still Wifi does not work!
    I can enable the service, device is known in device manager and it also finds Wifi networks, but when i connect, after entering password, Explorer.exe crashes!
