Windows Server waxay siisaa qalab aad u badan oo loogu talagalay maamulayaasha haddii codsi ama kumbuyuutarku aanu awoodin inuu ku xidho deked gaar ah ama server IP. Mid ka mid ah shay isla markiiba soo baxa ayaa isticmaalaya qalab lagu xalliyo DNS iyo arrimaha kale ee shabakadaha, laakiin haddii aad jeceshahay isticmaalka PowerShell , waxaa jira amar cajiib ah Test-NetConnection oo aad isticmaali karto.

^{(Troubleshoot Network)}Cilad ku samee arimaha isku xidhka shabakada PowerShell

Waxaad isticmaali kartaa Test-NetConnection cmdlet si aad u ogaato macluumaadka ogaanshaha xiriirka. Waxaa ka mid ah taageerada tijaabada Ping , tijaabada ^(Ping)TCP , baafinta dariiqa^{( route tracing)} , iyo waliba ogaanshaha xulashada dariiqyada.

Iyada oo ku xidhan xulashooyinka la isticmaalo, wax soo saarku wuxuu ka koobnaan doonaa macluumaadka sida  ComputerName , RemoteAddress , SelectedSourceAddress , OutgoingInterfaceIndex , SelectedNetRoute , iyo in ka badan.

Waa kan liiska cabbirrada la taageeray

• Dekadda guud ee TCP : Waxay qeexdaa lambarka dekedda TCP ee adeegga caadiga ah
• Magaca Kombiyuutarka: Wuxuu qeexayaa Nidaamka Magaca Domain-^{( Domain Name System)} ka ( DNS ) magaca ama cinwaanka IP-ga ee kombiyuutarka la beegsanayo.
• ConstrainInterface: Wuxuu qeexayaa xannibaadda is dhexgalka si loogu isticmaalo ogaanshaha waddooyinka.
• ConstrainSourceAddress: Wuxuu qeexayaa ciwaanka isha ee xannibaadda si loogu isticmaalo baarista dariiqa.
• DiagnoseRouting: Waxay tuseysaa in dariiqa ogaanshaha ay u socdaan si ay u soo saaraan dariiqa iyo isha xogta xulashada cinwaanka martigeliyaha fog.
• Hops: Wuxuu qeexayaa tirada boodboodka ee lagu dhex maro amarka raadraaca.
• Heerka Macluumaadka: Wuxuu qeexayaa heerka macluumaadka faahfaahsan ama xasilloon
• Deked : Waxay ku qeexdaa lambarka dekedda TCP ee kumbuyuutarka fog.
• TraceRoute: Waxay tuseysaa in Tracert uu u shaqeeyo si uu u tijaabiyo isku xirnaanta martigeliyaha fog.

Troubleshoot Windows Server Network connectivity issues via PowerShell

Windows Server offers tons of tools for admins in case an application or computеr is not able to connect to a specific port or server IP. One thing thаt instantly pops up is using tools to resolve DNЅ and other network issues, but if you love using PowerShell, there is a brilliant command Test-NetConnection that you can use.

Troubleshoot Network connectivity issues via PowerShell

You can use the Test-NetConnection cmdlet to find out diagnostic information for a connection. It includes support for the Ping test, TCP test, route tracing, and also route selection diagnostics.

Depending on which options are used, the output will consist of information such as ComputerName, RemoteAddress, SelectedSourceAddress, OutgoingInterfaceIndex, SelectedNetRoute, and more.

Here is the list of supported parameters

• CommonTCPPort: Specifies the typical service TCP port number
• ComputerName: Specifies the Domain Name System (DNS) name or IP address of the target computer.
• ConstrainInterface: Specifies the interface constraint to use for route diagnostics.
• ConstrainSourceAddress: Specifies the source address constraint to use for route diagnostics.
• DiagnoseRouting: Indicates that route diagnostics run to output the route and source address selection information for the remote host.
• Hops: Specifies the number of hops to traverse in a traceroute command.
• InformationLevel: Specifies the information level Detailed or Quiet
• Port: Specifies the TCP port number on the remote computer.
• TraceRoute: Indicates that Tracert runs to test connectivity to the remote host.

List of Sample Commands

Here are a few sample commands you can try on your computer. Some of these commands will need admin privileges, so make sure to launch PowerShell 7 or PowerShell 5.1 with the required permission.

When working with web services, it is to test a specific TCP port.

Test-NetConnection youtube.com -Port 443 -InformationLevel "Detailed"

Perform route diagnostics to connect to a remote host.

Test-NetConnection -ComputerName itopstalk.com -DiagnoseRouting -InformationLevel Detailed

Find the default port of a website

Test-NetConnection -ComputerName microsoft.com -CommonTCPPort HTTP

Run Trace Route for a website

Test-NetConnection -ComputerName google.com -TraceRoute

That said, it is beneficial if you are on a non-windows platform but uses the same command as in Windows.

Apart from this, I have also noticed executing commands for some websites like Microsoft.com. It doesn’t work. Ping fails all the time, which could be a server thing blocking such random requests.
