netsh interview questions
Top netsh frequently asked interview questions
Is there a way for me to import a .txt
file (with IP addresses on each line) into Windows Firewall?
I want each of the IP addresses to be completely blocked. That would also provide an easy way to unblock an IP address in the .txt
file later on (in combination with netsh
).
I am currently using Peerblock but it tends to cause some load on the CPU sometimes.

I've been trying to enable or disable a NIC on Windows 2003 Server from a Windows 2008 Server PC. After googling around a bit, the command should be something like this:
netsh -r remotecomputer interface set interface "interface name" disabled
But when I try it, I get this error: "The newname and enable/disable option for LAN interfaces is not valid when administrating a remote machine".
I have admin access on both systems, and they are on the same LAN.
Anybody knows the right way to do it?

So a coworker accidentally added an entire /20 (~4000 ips) to a Windows 2003 Server.
I generated a simple batch file with all the necessary lines to remove these IPs. The commands do work and remove the IPs as I want, but the problem is they take around 3 to 10 minutes to execute each line, and the CPU is staying > 90% utilization, svchost.exe and lsass.exe seem to be eating up the most cycles.
Anyone know why these netsh commands are taking so long to execute?
Example:
netsh interface ip delete address name="Local Area Connection" addr=10.10.150.24

How to redirect/route an IP address to another IP address?
E.g.: 10.10.10.10 -> 20.20.20.20 and then when I type in 10.10.10.10 in my browser, it connects to 20.20.20.20.
Let's assume 10.10.10.10 and 20.20.20.20 are external IP addresses.

I used the following command to trigger scan on WiFi interface netsh wlan show networks
. However I found that this command return Windows 7 scan result without sending them to the relevant WiFi driver.
Is there any command I should use to trigger scan to WiFi driver? Thanks

In the msdn docs for ssl configuration, there's this command:
netsh http show sslcert
But on my machine (Server 03) I don't have httpcfg command (looked in many places), netsh
doesn't have the http sub-command. How can I get the http sub-command to show up? I've tried using AddHelper with all the http*.dll's I could find. No luck.

Using netsh, I used the following command to add a wireless profile
add profile filename="c:\profiles\DLINK-Profile.xml" interface="D-Link DWA-125 N150"
All parameters are valid. But I get the error "An attempt was made to load a program with an incorrect format."
I know this error is related to OS architecture 64bit or 32 bit. But i'm not sure which program is not compatible.
I'm using Win7 64bit

I'm looking for a tool that works across windows (xp through 7) that will allow me to open a TCP connection to a specified ip and port. This functionality used to exist in windows xp (netsh diag connect iphost ), but the Netsh diag commands seem to have been removed in vista/7. I've been looking around for something similar, and I've searched Super User, but I can't seem to find anything.
Something that's already built into windows would be ideal, but a small executable that does this (preferably command line, standalone executable).
Edit: I should have specified further. I'm familiar with Telnet and putty, and it is what I currently use, however, I'm in an environment where I have to guide non-technical users through troubleshooting very technical problems over the phone, without any form of remote access (sounds fun, right?). While telnet works, it doesn't explicitly state whether or not the TCP connection was successful; you have to look at the title bar and the contents of the terminal output, which, for some reason, seems to be impossible to users. I'm looking for something with a clear "TCP Connection completed successfully/failed" type response, if such a tool exists.
Edit #2: Thanks to everyone who answered. All suggestions were good, despite the fact that I didn't post as clear a question as I should have. Thanks for the help.

I have created a hosted network in my windows7 system. The netsh wlan show hostednetwork
command gives the output
Hosted network settings
-----------------------
Mode : Allowed
SSID name : "rambo"
Max number of clients : 100
Authentication : WPA2-Personal
Cipher : CCMP
Hosted network status
---------------------
Status : Started
BSSID : xx:xx:xx:xx:xx:xx
Radio type : 802.11n
Channel : 11
Number of clients : 1
xx:xx:xx:xx:xx:xx Authenticated
But I have forgot the password for this connection and after some googling I found the command netsh wlan refresh hostednetwork YourNewNetworkPassword
. But on executing this command it get the error
C:\Users\user>netsh wlan refresh hostednetwork rambo123
Invalid value "rambo123" for command option "data".
Usage: refresh hostednetwork [data=]key
I have no idea what is wrong with this command.

When I type in admin console command to start hostednetwork netsh wlan start hostednetwork
it gives me this: The hosted network couldn't be started.
The group or resource is not in the correct state to perform the requested operation.
There is a hotfix from Microsoft but it didn't help me. Any advice?

I exported a wireless network connection profile from a Windows 7 machine correctly connected to a WiFi network with a WPA-TKIP passphrase. The exported xml file shows the correct settings and a keyMaterial
node which I can only guess is the encrypted passphrase.
When I take the xml to another Windows 7 computer and import it using netsh wlan add profile filename="WiFi.xml"
, it correctly adds the profile's SSID and encryption type, but a balloon pops up saying that I need to enter the passphrase.
Is there a way to import the passphrase along with all other settings or am I missing something about adding profiles?
Here is the exported xml with personal information removed:
<?xml version="1.0"?>
<WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1">
<name>[removed]</name>
<SSIDConfig>
<SSID>
<hex>[removed]</hex>
<name>[removed]</name>
</SSID>
<nonBroadcast>false</nonBroadcast>
</SSIDConfig>
<connectionType>ESS</connectionType>
<connectionMode>auto</connectionMode>
<autoSwitch>false</autoSwitch>
<MSM>
<security>
<authEncryption>
<authentication>WPAPSK</authentication>
<encryption>TKIP</encryption>
<useOneX>false</useOneX>
</authEncryption>
<sharedKey>
<keyType>passPhrase</keyType>
<protected>true</protected>
<keyMaterial>[removed]</keyMaterial>
</sharedKey>
</security>
</MSM>
</WLANProfile>
Any help or advice is appreciated. Thanks.
Update: It seems if I export the settings using key=clear
, the passphrase is stored in the file unprotected and I can import the file on another computer without issue. I've updated my question to reflect my findings.

How do I enable my network connection using command prompt?
I've tried:
netsh interface set interface "Local Area Connection" ENABLE
But received this error:
An interface with this name is not registered with the router.
I know how to disable my network connection using ipconfig/release but when I try ipconfig/renew using command prompt it doesn't seem to be working either.

I try to get the Virtual Wifi Adepter working on Win 7 Professional. I want to share the wifi connection (I think it does work with cable connection) and I'm pretty sure that the network card should be able to do this, since its a Dell notebook from last year (Dell XPS 15 with Intel wifi adapter). So far I did the following:
1) Starting cmd.exe
as admin
2) netsh wlan set hostednetwork mode=allow ssid=test key=testkey1
returns positive feedback (mode for the hosted network is allowed, SSID has been changed etc.)
3) netsh wlan show hostednetwork
returns what I previously entered
4) netsh wlan start hostednetwork
returns positive feedback (hosted network has been started)
5) In Control Panel\Network and Internet\Network and Sharing Center
you can see that the PC is connected with a wifi network using the wifi adapter and with the test network using one of the two the virtual adapters
6) netsh wlan show hostednetwork
returns an error (group or resource not in correct state for this action) and my mobile device does not find the proposed connection
I tried deleting/deactivating the two virtual network connections and deinstalling the two virtual wifi adapters in the device manager and rebooting. So far, I only read about the encountered error during the start command.
Any ideas how to fix that or how to start all over again in setting up the virtual wifi? This morning it worked, except for the shared internet which would be the next step. (but using an additional cable connection, which I will try out later tonight and let you know)
Cheers,
Daniel
