If Finacle is not opening or you are facing a Finacle connectivity/opening issue, the problem may sometimes be related to the DNS configuration or Host File on your computer.

In such cases, the existing DNS address may need to be replaced with the updated DNS address, and the Windows Host File may also need to be updated.

Updated DNS Address for Finacle

If your system is currently using:

Old DNS: 172.16.20.26

Replace it with:

New DNS: 172.24.20.26

After changing the DNS, save the settings and restart the network connection.

How to Change DNS in Windows

Follow the steps below to change the DNS address:

1. Open Control Panel on your computer.
2. Go to Network and Internet.
3. Open Network and Sharing Center.
4. Click on Change adapter settings.
5. Right-click on your active Ethernet connection.
6. Select Properties.
7. Select Internet Protocol Version 4 (TCP/IPv4).
8. Click on Properties.
9. Select Use the following DNS server addresses.
10. Replace the old DNS address:

172.16.20.26

with:

172.24.20.26

11. Click OK and then Close.

Restart the network connection after making the changes.

Update the Windows Host File

If Finacle is still not opening after changing the DNS, the Windows Host File may also need to be updated.

The Host File is generally located at:

C:\Windows\System32\drivers\etc\hosts

Steps to Update Host File

1. Open the Start Menu.
2. Search for Notepad.
3. Right-click on Notepad and select Run as administrator.
4. In Notepad, click File → Open.

5. Navigate to:

   C:\Windows\System32\drivers\etc

6. Change the file type from Text Documents (*.txt) to All Files.
7. Select the hosts file.
8. Open the file.
9. Update the Finacle-related host entry as instructed by your office/IT support.

Important: Do not delete or modify unrelated entries in the hosts file. Use only the hostname/IP details provided by your authorized Finacle or network administrator.

Flush DNS After Making Changes

After changing the DNS and updating the Host File, open Command Prompt as Administrator and run:

ipconfig /flushdns

You should see a message similar to:

Successfully flushed the DNS Resolver Cache.

After this, close and reopen the browser and try accessing Finacle again.

Check Whether the New DNS Is Working

You can also verify the DNS configuration using Command Prompt.

Run:

ipconfig /all

Check the DNS Servers section and confirm that the updated DNS address is being used:

172.24.20.26

You can also use:

nslookup

to check whether the required Finacle hostname is resolving correctly.

Finacle Still Not Opening?

If Finacle continues to show an opening or connectivity error after changing the DNS and Host File, check the following:

• Confirm that the new DNS 172.24.20.26 is configured correctly.
• Make sure the Host File was saved with the correct filename and location.
• Run ipconfig /flushdns.
• Restart the browser.
• Check your LAN/network connection.
• Restart the computer if required.
• Contact your authorized network/Finacle support team if the problem continues.

Quick Summary

Note: DNS and Host File values can be environment-specific. The above DNS change should be made only where the updated address has been officially provided for your Finacle/network environment.
