How to Clear or Flush Google Chrome DNS Cache

Last Updated on: August 2, 2023 by Ramesh

Domain Name System (DNS) is the address book of the Internet. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.

Windows caches the DNS records for a considerable time. This cache can be cleared by running the command ipconfig /flushdns. Other than this, your web browser like Google Chrome maintains a separate DNS cache mechanism.

Why do you need to clear the browser DNS cache?

System administrators often find times where they need to redirect the domains by editing the host file, in order to override any DNS records for a domain name. However, every time you want to change a hostname to a different IP, you needed to close the browser before the change will take effect. This can get tedious if you have too many browser tabs or windows open.
When doing web development or other work that requires changing the web hosting IP in the HOSTS file for testing purposes, you needed to restart the web browser every time for the new host to IP mappings to take effect.

However, with Google Chrome, you can clear the internal DNS cache without closing and reopening the browser. This post tells you how to clear the internal DNS cache of the Google Chrome browser without restarting Google Chrome.

[Fix] “Start, Taskbar, and Action Center” Accent Color Setting Greyed Out

Last Updated on: August 8, 2023 by Ramesh

After installing the Windows 10 Feature Update 1903 or higher, you may have noticed that the accent color checkbox Start, taskbar, and action center is grayed out. The recent Windows 10 versions come with a new Light Theme (“Light” color mode) that displays the Taskbar, Start menu, action center, notification area pop-ups, etc., in light grey color.

When the light color mode is enabled for Windows, the Taskbar, Start menu, and the action center can’t be colorized, which is why those settings are dimmed out. This is by design. You’ll be able to show an accent color for window title bars and borders, though.

Here is how to enable the dark color mode for Taskbar, Start Menu, and the Action Center. The current version of Windows 10 is 20H2 as of this post, and the instructions apply to version 20H2 as well.

[Fix] Mapped Network Drives don’t work in Windows 10 v2004

Last Updated on: August 8, 2023 by Ramesh

After updating to Windows 10 version 2004, mapped network drives don’t reconnect after a restart. Here are some of the symptoms you may be experiencing:

Mapped drives that link to your NAS (e.g., Synology, ReadyNAS, etc.) or Windows 2000/XP/2003 computers do not work after upgrading to Windows 10 v2004. Remapping the drive works only for the current session. Enabling the SMB 1.0/CIFS File Sharing support in Windows Features dialog also doesn’t help.
As soon as the computer restarts, a red X sign appears on the mapped drive, and the drive doesn’t reconnect. The following error appears when you attempt to access the mapped drive:

Restoring Network Connections

An error occurred while reconnecting z: to \\computername\share_name

Microsoft Windows Network: The local device name is already in use.

This connection has not been restored.
The UNC paths to network shares work correctly, but only if you haven’t already mapped a drive letter to the share. If not, the following error occurs when you access the share using the UNC path: (e.g., \\computername\share_name)

\\computername\share_name is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.
When you try to connect to the network share using \\servername\share_name or \\IP_Address\share_name using the correct domain\username and password, you may get the error code 0x80070043 - The network name cannot be found.

Many users have rolled-back Windows 10 to version 1903 or v 1909 due to the above issues.

Let’s see how to fix this issue without having to rollback Windows 10 to v1909 or v1903.
