How to test remote computer connectivity using PowerShell?
To test the remote connectivity using PowerShell Test-Connection command is used. PowerShell also supports the Ping command and both the commands are almost produce the same output but Test- Connection cmdlet supports advanced parameters. See how both commands output look.
Ping Command −
PS C:\Temp> ping Test1-Win2k16 Pinging Test1-Win2k16 [192.168.0.108] with 32 bytes of data: Reply from 192.168.0.108: bytes=32 time<1ms TTL=128 Reply from 192.168.0.108: bytes=32 time=1ms TTL=128 Reply from 192.168.0.108: bytes=32 time=1ms TTL=128 Reply from 192.168.0.108: bytes=32 time=1ms TTL=128 Ping statistics for 192.168.0.108: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 1ms, Average = 0ms
Test-Connection command output −
PS C:\Scripts> Test-Connection Test1-win2k16 Source Destination IPV4Address IPV6Address ------ ----------- ----------- ----------- ADDC Test1-win2k16 192.168.0.108 ADDC Test1-win2k16 192.168.0.108 ADDC Test1-win2k16 192.168.0.108 ADDC Test1-win2k16 192.168.0.108
You can reduce the number of checks using -Count parameter. It is similar to -n in the ping command.
Example
PS C:\Scripts> Test-Connection Test1-win2k16 -Count 2 Source Destination IPV4Address IPV6Address ------ ----------- ----------- ----------- ADDC Test1-win2k16 192.168.0.108 ADDC Test1-win2k16 192.168.0.108
If you need to perform the above command quietly then you can use -Quiet parameter which gives a Boolean (True or False) output if the connection is successful or fails respectively.
PS C:\Scripts> Test-Connection Test1-win2k16 -Count 2 -Quiet True
Test-Connection has the advantage that it supports common parameters like dealing with errors. In the below example, Any-Comp server doesn’t exist. To catch the error when the server is not reachable or server name doesn’t exist then we will use the ErrorAction parameter supported by cmdlet.
try {
Test-Connection Any-Comp -Count 2 -ErrorAction Stop
}
catch {
$_.Exception.Message
}Output
Testing connection to computer 'Any-Comp' failed: Cannot resolve the target name.
