Nigh of the fourth dimension, the issue occurs when the user tries to run a netsh command. Some users are reporting that for them, the mistake bulletin appears when they try to right-click a website in the IIS (Internet Information Services ) MMC (Microsoft Management Console) snap-in.

The process cannot access the file considering information technology is being used past another process

The issue is reported to occur on Windows Vista, Windows 7, Windows 8.1, Windows 10 and on diverse Windows Server versions.

What causes the procedure to be used past another process?

We investigated this particular outcome by looking at various user reports and the repair strategies that they used to get the event resolved. Based on what we were able to gather, at that place are several common scenarios that will trigger this detail error message:

The control requires admin privileges – If y'all're encountering the mistake inside a terminal, it's most likely because you don't have administrative privileges to make the modifications. Several users in a similar situation have managed to get the issue resolved past granting admin privileges.
Another process is using port 80 or port 443 – This is typical with computers running IIS (Internet Information Services). If some other process is using these two ports, you will run across this error bulletin.
The ListenOnlyList registry subkey is not configured correctly – Another common scenario with IIS (Internet Information services) that will trigger this particular error is an incorrectly configured ListenOnlyList registry subkey.

If you're currently struggling to resolve this particular error message, this article will provide y'all with a collection of verified troubleshooting steps. Down below, you accept a collection of methods that other users in a similar situation have used to get the event resolved.

For the best results, follow the methods below in order until you encounter a fix that is constructive in resolving the error in your item scenario.

Permit's brainstorm!

Method 1: Running the control with admin privileges

If you're getting this error when trying to run a netsh command, it's probable that the error is occurring because you lot don't have admin privileges. This is reported to occur more than than often when the user tries to run a command that adds exclusions to the dynamic port range for native Windows apps or 3rd party application.

Keep in mind that an operation of this kind volition crave administrator privileges. To ensure that the CMD window you're trying to perform the activity in has admin privileges, follow the steps below:

Press Windows key + R to open a Run dialog box. Then, type "cmd" and press Ctrl + Shift + Enter to open up an elevated Command Prompt.

Opening an elevated Control Prompt window
When prompted past the UAC (User Account Control), click Yes to grant admin privileges.
In the elevated Command Prompt, run the command again and come across if you're still encountering the same error message.

If y'all're nonetheless getting the "The procedure cannot access the file considering information technology is being used by some other process" error or this scenario wasn't applicable, move down to the side by side method below.

Method 2: Setting a dissimilar IP range

If you're trying to resolve a conflict DNS conflict using netsh and the method above didn't assist you, you might want to endeavour a unlike approach.

Several users struggling to resolve the same error message have constitute that the conflict is resolved subsequently they tried to ready a completely unlike IP range instead of creating an exclusion range.

Below you have a couple of commands that i affected user successfully ran to resolve a disharmonize betwixt DNS and Quickbooks:

              netsh int ipv4 set dynamicport tcp start=10000 num=m netsh int ipv4 set dynamicport udp beginning=10000 num=1000

Notation: Ensure that the concluding y'all're running the control in has admin privileges.

If this method didn't resolve the conflict or wasn't applicable to the situation that you're encountering, movement downward to the last method.

Method 3: Resolving the IIS port conflict

If you are encountering the upshot while trying to correct-click a website item within the IIS MMC snap-in (clicking Start doesn't practise anything), y'all'll demand to utilize the Netstat.exe utility to figure out if another procedure is using port 80 and port 443.

This issue is quite common with computers running Microsoft IIS 6.0 and 7.0. Based on the official Microsoft documentation, the mistake message will appear if i of the following conditions are applicable to your current situation:

The ListenOnlyList registry subkey is not configured correctly on the IIS running estimator.
Some other procedure is using the TCP port (80) or the SSL port (443) required by the IIS.

To resolve this consequence, we'll demand to deploy the Netstat.exe utility in order to determine if another procedure is using the ports specified above. If the utility determines that the ports are not beingness used, we'll examine the ListenOnlyList subkey to see if information technology'south correctly configured.

Here's a step-by-step guide through the whole matter:

Press Windows central + R to open a Run dialog box. Then, type "cmd" and press Ctrl + Shift + Enter to open up up an elevated Control Prompt. When prompted by the UAC (User Account Control), click Yes to grant authoritative privileges.

Opening an elevated Command Prompt window
Within the elevated command prompt, run the following command to kickoff the Netstat.exe utility:
```
netstat -ano
```
In one case you get a return, roll through the listing of Agile Connections and verify whether the ports 50 and 443 are beingness actively used by a dissimilar process.

Verifying if the ports are beingness used past a different process

Note: If the ports are being actively used past a different process, y'all've just managed to place the source of your trouble. In this case, wait online for specific steps on how to resolve the port conflict according to the PID of the port.
Close the elevated Control Prompt every bit nosotros won't demand admin privileges for the side by side steps.
If the ports aren't actively used, press Windows key + R to open upwardly a Run dialog box. And then, type 'regedit' and printing Enter to open the Registry Editor. When prompted by the UAC (User business relationship control), click Yes to grant administrative privileges.

Opening the Registry Editor utility
Within the Registry editor, use the left pane to navigate to the following location:
```
                  HKEY_LOCAL_MACHINE\Organization\CurrentControlSet\Services\HTTP\Parameters\ListenOnlyList                
```
Notation: In case the ListenOnlyList subkey is not present, there's no need to create 1 every bit an IP address of 0.0.0.0 will exist used by default.
Before you go ahead and modify the ListenOnlyList subkey, you'll demand to stop the HTTP service that is running the IIS. So put the Registry Editor in the background equally we'll return to it in a moment.
Next, press Windows key + R to open a Run dialog box, type 'cmd' and press Enter to open another Command Prompt window.

Run dialog: cmd
In the Cmd prompt, run the post-obit command and press Enter to stop the HTTP service responsible for running the IIS:
```
net stop http
```
When asked whether you want to continue this functioning, blazon 'Y' and press Enter to ostend the operation.

Disabling the HTTP Service
Once the HTTP service is disabled, close the Command Prompt window and render to the Registry Editor.
With the ListenOnlyList subkey selected, move over to the right-manus pane and ensure that information technology contains valid IP addresses. If you spot an IP address that isn't valid, remove it or modify it to reverberate an entry with a valid IP address.

Deleting the Binary values with invalid IPs

Note: In case the ListenOnlyList subkey is nowadays and the 0.0.0.0 address is listed, you need to delete all the other IP addresses.
Close Registry Editor and restart your computer.
At the next startup, the HTTP service should exist automatically started. Just just to make sure, printing Windows key + R to open up some other Run dialog box. Then, type "cmd" and press Enter to open a Command Prompt window.

Opening a normal Command Prompt window

```
                  net start http                
```
Note: If you become returned a message proverb that "The requested service has been already started" you are good to become.
Attempt to start a service from the Microsoft Internet Information Services (IIS) Microsoft Direction Console (MMC) snap-in. You should no longer encounter the 'process cannot access the file because it is beingness used by another procedure' mistake.
