You may be wondering why this is a daily task. Verify that your AIS configuration is active.
This message indicates that a background job is running for user xxxx but user xxxx is not active. Also check for the message “Failed to activate authorization check for user xxxx” where xxxx is a user ID. Review all failed logon attempts, ID locks due to failed logon attempts, and errors that result in program dumps. Again, we are looking for the same things as with SM04, suspicious IDs, or IDs being shared. Remember, AL08 is an alternate for SM04 and lets you review logged-on users across multiple servers if your system is configured with multiple servers. Are there any unrecognizable user IDs (IDs not following the naming convention, and so on)? AL08 – Users Logged On Are all users using the defined logon groups? Are users logging on using multiple machines? You can check the terminal the user ID is coming from and if the same user ID is logged on from multiple terminals, then that ID is probably being shared. SM04 – User OverviewĪdministrators should consider doing spot checks throughout the day to monitor users and their activities. I suggest you perform the following every day, possibly in the morning and then in the afternoon to monitor your system. In SAP Security Configuration and Deployment, 2009 Daily Tasks Ensure logging is implemented, but make sure it does not cause more harm than good. Situations may exist where so much logging is done that it actually camouflages the attacker's efforts. Administrators should constantly be making adjustments to the logging system to reduce logging traffic that can be considered “white noise.” White noise is where too much is being logged and administrators cannot make heads or tails of all the data presented to them via the logging system. Lastly, implementing logging is not something that is done and forgotten about. Time stamping logs and using a synchronized time server on network hosts may allow administrators or forensic analysts to trace the attacker's steps back through the network to help identify the initial breach point. Logging and time stamping logs to a centralized server can help ensure logs are able to be viewed in the event an attacker attempts to clear the local system logs. System logs should be configured to log critical security events to centralized and redundant servers. When implementing a logging initiative, it is vital to ensure usability of the logging system and redundancy. Reducing the active attack window is vital to helping preserve the stability and integrity of the network. Logging once properly configured and implemented can also help an organization by reducing the reaction time from when an attack begins and when an administrator is notified and can deploy countermeasures. Logging is an important part of security that allows administrators to be notified of potentially dangerous attack against its network and assets. Many times, organizations do not spend enough time implementing detective controls as it applies to tracking access and logon violations. In Scenario 3: Timed Attacks to Circumvent Lockouts, we explored an attack that should have caused a lot of logs to be generated due to failed logon attempts.

This means you do not have PC or Domain related issues. If everything is fine, then RDP should work. – Temporarily disable your Anti-Virus agent to test for possible issues.

– Check if RDP is enabled and allowed on your firewall as this can be easily overwritten by mistake or broken by Windows Update. If you are able to ping the server, and the following below are correct, then the issue is half solved.

The following are the various user IDs I tried and none of them was successful Note: This does not relate to the Password issues: The password is correct and existing authentication via RDP was possible.
While using this Remote Desktop feature on Windows 10, you might encounter a “logon attempt failed” error as shown in the figure above.
