8. Conclusion

What is Login Timestamp Error (40105)?

The Login Timestamp Error (40105) is an authentication error that occurs when the system time on your laptop differs significantly from the company's authentication server. Error 40105

Most organizations use technologies such as Active Directory, Kerberos Authentication, or Single Sign-On (SSO), which rely on accurate timestamps to validate login requests.

If the time difference exceeds the allowed limit, authentication fails.

Why Does This Error Occur?

The company's authentication server verifies your computer's system time before allowing access.

If your laptop clock is incorrect, Windows sends an invalid timestamp during authentication, causing the login request to fail. Windows Time Service


Common causes include:

• Incorrect BIOS date and time
• Windows Time service stopped
• Laptop disconnected from VPN for a long period
• CMOS battery issue
• Failed time synchronization with the domain controller

Quick Fix 1: Restart Windows Time Service

If you're able to sign in to Windows, restart the Windows Time service.

Steps

• Press Win + R
• Type services.msc
• Press Enter
• Locate Windows Time
• Right-click it
• Select Restart

If the service is stopped, click Start.
This forces Windows to begin time synchronization again.
Tip: You can also restart the service from Command Prompt (Run as Administrator):

• net stop w32time
• net start w32time

Quick Fix 2: Correct the Date and Time from BIOS (UEFI)

If Windows displays an incorrect time before connecting to the network, verify the BIOS clock. Login Timestamp Error 40105

Steps

Restart the laptop.
Enter BIOS/UEFI (usually F2, F10, F12, Delete, or Esc).
Navigate to Date & Time.
Update the correct date and time.
Press F10 to save.
Restart Windows.

Note: BIOS only stores the hardware clock. It does not synchronize with internet time servers.

How Windows Time Synchronization Works

After Windows starts and the device has network connectivity, it synchronizes the system clock using Network Time Protocol (NTP). Bad Timestamp Error

Key Information:

If the device cannot communicate with the domain controller or NTP server, the system time may become inaccurate.Login Timestamp Error Domain Login Error

Additional Troubleshooting

If the issue still exists, try the following:

• ✅ Connect the laptop to the company VPN.
• ✅ Restart the computer.
• ✅ Ensure Windows Time service is running.
• ✅ Verify the correct Time Zone.

• ✅ Run Windows Update.
• ✅ Contact your IT administrator if the device belongs to a corporate domain.

Frequently Asked Questions (FAQ)

What causes Login Timestamp Error (40105)?
The most common cause is an incorrect system date and time.

Can a VPN connection fix this issue?
Yes. Once connected to the corporate VPN, Windows may synchronize the system time with the company's domain controller.

Does changing BIOS time permanently fix the issue?
It fixes the hardware clock, but Windows still synchronizes time using the Windows Time service after startup.

Which protocol is used for Windows time synchronization?
Windows uses Network Time Protocol (NTP) over UDP Port 123.

Can a dead CMOS battery cause this error?
Yes. If the CMOS battery is weak, the BIOS clock may reset after every shutdown, causing repeated timestamp errors.

Conclusion

The Login Timestamp Error (40105) is usually caused by an incorrect system clock rather than a problem with your user account.

In most cases, restarting the Windows Time service or correcting the BIOS date and time resolves the issue. Once the laptop synchronizes with the company's authentication server, users should be able to sign in successfully.

If the problem continues, connect the laptop to the corporate VPN or contact your organization's IT support team for further assistance.

Login Timestamp Error or Bad Timestamp Error on a Company Laptop

One user's company laptop was showing a Login Timestamp Error or Bad Timestamp Error (40105) while trying to log in.
This type of error usually occurs because your computer's date and time are out of sync with the company's security server.
It commonly happens when the laptop has been disconnected from the company network or VPN for a long time.

Why Does This Error Occur?

The company's authentication servers verify your system time before allowing access.

If your laptop's clock is incorrect, the authentication request may fail and display a Bad Timestamp or Timestamp Error (40105).

Quick Fix 1: Restart the Windows Time Service

If you're able to log in to Windows, follow these steps:

• Press Win + R, type services.msc, and press Enter.
• Locate Windows Time.
• Right-click it and select Start or Restart.

This will restart the Windows Time service and may synchronize the system clock.

Quick Fix 2: Correct the Date and Time from BIOS (UEFI)

If Windows time is incorrect and you cannot sync it, you can manually update the date and time from the BIOS.

Steps:

• Restart your computer and enter the BIOS/UEFI by pressing the manufacturer-specific key (usually F2, F10, F12, Esc, or Del).
• Navigate to the Main, System Configuration, or Miscellaneous Settings section.
• Locate Date & Time.
• Update the correct date and time.
• Press F10 to save the changes and restart the laptop.

Note: Most BIOS/UEFI firmware allows you to set the date and time manually, but it does not automatically synchronize with internet time servers.

How Time Synchronization Actually Works

The actual time synchronization happens inside the Windows operating system, not in the BIOS.

After Windows starts and the device has network connectivity, it synchronizes the system clock using Network Time Protocol (NTP).

NTP uses UDP Port 123 for both client requests and server responses, making it the standard protocol for time synchronization across networks.

Conclusion

A Login Timestamp Error or Bad Timestamp Error (40105) is usually caused by an incorrect system clock rather than an account issue.

In most cases, restarting the Windows Time service or correcting the BIOS date and time resolves the problem. Once the system time matches the company's authentication server, the user should be able to log in successfully.
