BAT file for Initial Diagnosis of Network Problems

I have updated this Post to make it easier for members to link to when helping others.

The Batch Script is intended to be used for 'Network Diagnostics' [ or general informational purposes ]. This is only an initial step in the diagnostics process, and will allow us to rule out potential causes and problems.

Simply download and run the following Batch file [ it will take a minute or two ].

A special thanks to @MaloK for his input and contributions.

If you would rather create your OWN Batch file, here is the code . . .

Code:

@echo off

   Note

The following is the ORIGINAL start of this post for continuity . . .

Good afternoon,

We often ask for members to initially run ipconfig /all and Post the results.

To get some additional information that might prove to be helpful at the same time that they run ipconfig /all, I wrote the following Batch Script which I use. Is there ANY reason that the results output should NOT be posted because of sensitive information etc . . .

Code:

@echo off

ipconfig /all

echo. & echo ^>Ping www.Google.com . . .

echo ^>NSLookup 8.8.8.8 [ www.Google.com ] . . . & echo.
nslookup 8.8.8.8
echo ^>Press ANY key to EXIT . . . & pause >nul & Exit

I have deliberately used Google TWICE on ping and tracert to give more thorough diagnostic results.

If it is OK, then I will obviously Post it as an attachment, and possibly add the Script underneath. This way, any members that want to use it in Posts, can.

I do NOT intend to add ANYTHING else to the above as this is just an initial collection of data results that may help with quicker diagnosis and resolution.

Thanks.

Is an IP address sensitive information?

This is why I asked.

One of the first things that a member is asked to run when there is a problem is ipconfig /all, which obviously contains the IP Address. When you think about it, that information will show if there is a problem straight away, and if NOT, it can be ruled out as a cause and further investigation and diagnostics can then continue.

Hello @Calm Horizons,

Calm Horizons said:

The IP address returned by the ipconfig /all should not be an issue as the one returned would be an RFC1918 address in almost every instance that I can think of (there will be exceptions obviously but those would be few and far between).

Thanks for the input. That was my thinking as the ipconfig /all results have always been posted, and I am sure that if there was a potential security risk that it would have been reported or mentioned long ago in the Threads concerned.

Calm Horizons said:

All other information for example from the tracert command is information that anyone could find so nothing of note there.

I agree, I just want to try and cover all bases.

Hello @MaloK,

Thanks for the reply.

You could use . . .

Code:

netsh interface show interface
netsh interface ip show interfaces
netsh mbn show interfaces

Instead of using Powershell, it would make the script more universal. And your ipconfig /all gives all relevant info in one step.

Yes, there are MANY different Commands that could be included to produce results, such as these two just as an example . . .

Code:

PowerShell "Get-NetAdapter -Name * -IncludeHidden | Select Name, InterfaceDescription, ifIndex, Status, MacAddress, LinkSpeed, DriverFileName, DriverDate, DriverVersion, NdisVersion | Sort-Object -Property Name | Format-Table | Out-String -Width 1000"

PowerShell "Get-NetAdapter -Name * -IncludeHidden | Select Name, InterfaceName, AdminStatus, MacAddress, MediaType, PhysicalMediaType, ConnectorPresent | Sort-Object -Property Name | Format-Table -Autosize | Out-String -Width 1000"

. . . but this is getting into a different scope of what I intended for this thread, which is to find out if ANY of the information is classed as sensitive.

The Script is purely a quick initial way to run and produce results that can be used for diagnostics. I just thought that it would help members helping members with problems if they wanted to use and post it.

Matthew Wai said:

The code in post #1 shows my IP address, which reveals my exact location.

Well, it gives the area, NOT the ACTUAL address.

I suppose it is a case of whether people want help or NOT. I don't remember ANY members NOT wanting to post the ipconfig /all results because of this, can you Matthew?
