When you use an account that is not a member of the Administrators group to try to

log on to a computer that is running Windows Server 2003 or Windows XP, you may receive the following message in the “Log On to Windows”

window:

The security log on this system is full. Only administrators can log on to fix the problem.

You can log on to

the computer by using an account that is a member of the Administrators group. However, if you log on to the computer remotely, you may receive the following

message:

The security log on this system is full.

This issue occurs because no more events can be logged to the Security log

on the computer. When events cannot be written to the Security log, only accounts that are members of the Administrators group can log on to the

computer.

To resolve this issue, use an account that is a member of the Administrators group to log on to the computer. Then, follow these steps to

specify that Security log events can be overwritten:

1. Click Start, point to All Programs, point to Administrative Tools, and then click Event

Viewer.
2. Right-click Security, and then click Properties.
3. In the Log Size area of the Security Properties window, click the Overwrite events as

needed option under When maximum log size is reached.
4. Click OK.
5. Close Event Viewer.

Non-administrative users will now

be able to log on via Termianl Services.
