Problemer med internetforbindelse^(Internet) ? DNS -cache ødelagt? Står du over for DNS-problemer eller -problemer^{(DNS issues or problems)} ? Måske skal du tømme Windows DNS-cache^{(flush Windows DNS Cache)} . Hvis din computer har svært ved at nå et bestemt websted eller en bestemt server, kan problemet skyldes en korrupt lokal DNS - cache. Nogle gange cachelagres dårlige resultater, måske på grund af DNS-cacheforgiftning og spoofing^{(DNS Cache Poisoning and Spoofing)} , og de skal derfor ryddes fra cachen for at tillade din Windows -computer at kommunikere med værten korrekt.

Typisk er der tre typer caches in Windows 11/10 , som du nemt kan skylle ud:

1. Hukommelsescache^{(Memory Cache)}
2. DNS-cache
3. Thumbnails cache

Rydning af hukommelsescachen^{(Memory Cache)} kan frigøre noget systemhukommelse, mens rydning af miniaturecachen^{(Thumbnail Cache)} kan frigøre plads på din harddisk. Rydning af DNS-cachen^{(DNS Cache)} kan løse dit internetforbindelsesproblem. Sådan kan du tømme DNS - cachen i Windows 11 , Windows 10, Windows 8 eller Windows 7.

Skyl DNS-cache i Windows 11/10

For at tømme DNS-cachen^{(DNS Cache)} i Windows 11/10 skal du:

1. Åbn et administrativt kommandopromptvindue som administrator
2. Skriv ipconfig /flushdns og tryk på Enter
3. Du bør se – Windows IP-konfiguration^{(Windows IP Configuration)} . DNS Resolver Cache blev tømt
4. Afslut CMD
5. Din DNS -cache burde være blevet nulstillet.

Lad os se det lidt mere detaljeret.

Du skal åbne et administrativt kommandopromptvindue. Skriv cmd^(cmd) i søgefeltet . Højreklik derefter på den og vælg ' Kør^(Run) som administrator' mulighed. Alternativt kan du også åbne en forhøjet kommandoprompt fra WinX- menuen.

Skriv derefter følgende og tryk enter:

ipconfig /flushdns

Du burde kunne se et bekræftelsesdialogvindue:

Windows IP Configuration. Successfully flushed the DNS Resolver Cache.

Vores freeware FixWin til Windows 10^{(FixWin for Windows 10)} lader dig tømme DNS - cachen osv. med et klik.

Vis DNS-cache

Hvis du ønsker at bekræfte, om DNS -cachen er blevet ryddet, kan du skrive følgende kommando og trykke på Enter :

ipconfig /displaydns

Dette viser eventuelle DNS-cache-^{(display the DNS cache)} poster.

Slå DNS-cache fra eller til

For at slå DNS -cache fra for en bestemt session skal du skrive net stop dnscache og trykke på Enter.

For at slå DNS-cache til, skal du skrive net start dnscache og trykke på Enter.

Når du genstarter computeren, vil DNC-cachen naturligvis under alle omstændigheder være slået til.^{(Of course, when you restart the computer, the DNC caching will, in any case, be turned on.)}

Deaktiver DNS-cache

Hvis du af en eller anden grund ønsker at deaktivere DNS -cachelagring, skal du skrive services i start søgning og trykke på Enter for at åbne Services Manager . Find DNS Client -tjenesten her.

The DNS Client service (dnscache) caches Domain Name System (DNS) names and registers the full computer name for this computer. If the service is stopped, DNS names will continue to be resolved. However, the results of DNS name queries will not be cached and the computer’s name will not be registered. If the service is disabled, any services that explicitly depend on it will fail to start.

Dobbeltklik på den for at åbne dens egenskabsboks^(Properties) . Skift her dens opstartstype fra Manuel^(Manual) til Deaktiveret^(Disabled) . Hvis du deaktiverer DNS-klienttjenesten^{(DNS Client)} , kan DNS^{(DNS Lookups)} -opslag  tage længere tid.

How to Clear, Reset, Flush DNS Cache in Windows 11/10

Internet connection problems? DNS cache corruрted? Facing DNS issues or problems? Maybe you need to flush Windows DNS Cache. If your computer is finding it difficult to reach a certain website or server, the problem may be due to a corrupt local DNS cache. Sometimes bad results are cached, maybe due to DNS Cache Poisoning and Spoofing, and therefore need to be cleared from the cache to allow your Windows computer to communicate with the host correctly.

Typically, there are three types of caches in Windows 11/10 that you can flush easily:

1. Memory Cache
2. DNS Cache
3. Thumbnails Cache

Clearing the Memory Cache can free up some system memory while clearing the Thumbnail Cache can free up space in your hard disk. Clearing the DNS Cache can fix your internet connection problem. Here’s how you can flush the DNS cache in Windows 11, Windows 10, Windows 8 or Windows 7.

Flush DNS Cache in Windows 11/10

To flush the DNS Cache in Windows 11/10 you need to:

1. Open an administrative command prompt window as an administrator
2. Type ipconfig /flushdns and hit Enter
3. You should see – Windows IP Configuration. Successfully flushed the DNS Resolver Cache
4. Exit CMD
5. Your DNS cache should have been reset.

Let us see it in a bit more detail.

You need to open an administrative command prompt window. In search box, type cmd. Then, right-click on it and choose ‘Run as administrator’ option. Alternatively, you can also open an elevated command prompt from the WinX menu.

Next, type the following and hit enter:

ipconfig /flushdns

You should be able to see a confirmation dialog window:

Windows IP Configuration. Successfully flushed the DNS Resolver Cache.

Display DNS Cache

If you wish to confirm if the DNS cache has been cleared, you can type the following command and hit Enter:

ipconfig /displaydns

This will display the DNS cache entries if any.

Turn Off or Turn On DNS Cache

To turn off DNS caching for a particular session, type net stop dnscache and hit Enter.

To turn on DNS caching, type net start dnscache and hit Enter.

Of course, when you restart the computer, the DNC caching will, in any case, be turned on.

NOTE: Here’s a Batch File to Release TCP/IP, Flush DNS, Reset Winsock, Reset Proxy all at once.

Disable DNS Cache

If for some reason you wish to disable DNS caching, type services in start search and hit Enter to open the Services Manager. Here locate the DNS Client service.

The DNS Client service (dnscache) caches Domain Name System (DNS) names and registers the full computer name for this computer. If the service is stopped, DNS names will continue to be resolved. However, the results of DNS name queries will not be cached and the computer’s name will not be registered. If the service is disabled, any services that explicitly depend on it will fail to start.

Double-click on it to open its Properties box. Here change its startup type from Manual to Disabled. If you disable the DNS Client service, DNS Lookups may take longer.
