Windows RDP Event IDs Cheatsheet

Simple Guidance For You In Windows RDP Event IDs Cheatsheet.

It is becoming more and more common for bad actors to manipulate or clear the security event logs on compromised machines, and sometimes RDP sessions don’t even register as just a type 10 logon, depending on the circumstance. RDP activities will leave events in several different logs as action is taken and various processes are involved.

For RDP Success refer the Event ID 4624 Logon Type from the below table to identify the Logon Service/Mode

Event ID 4624 – An account logon type

Logon TypeLogon TitleDescription
2InteractiveA user logged on to this computer
3NetworkA user or computer logged on to this computer from the network
4BatchBatch logon type is used by batch servers, where processes may be executing on behalf of a user without their direct intervention
5ServiceA service was started by the Service Control Manager
7UnlockThis workstation was unlocked
8Network CleartextA user logged on to this computer from the network. The user’s password was passed to the authentication package in its unlashed form. The built-in authentication packages all hash credentials before sending them across the network. The credentials do not traverse the network in plaintext (also called cleartext)
9New CredentialsA caller cloned its current token and specified new credentials for outbound connections. The new logon session has the same local identity, but uses different credentials for other network connections
10Remote InteractiveA user logged on to this computer remotely using Terminal Services or Remote Desktop
11Cached InteractiveA user logged on to this computer with network credentials that were stored locally on the computer. The domain controller was not contacted to verify the credentials

For RDP Failure refer the Event ID 4625 Status Code from the below table to determine the Logon Failure reason

Event ID 4625 – Status Code for an account to get failed during logon process

Status\Sub-Status CodeDescription
0XC000005EThere are currently no logon servers available to service the logon request
0xC0000064User logon with misspelled or bad user account
0xC000006AUser logon with misspelled or bad password
0XC000006DThe cause is either a bad username or authentication information
0XC000006EIndicates a referenced user name and authentication information are valid, but some user account restriction has prevented successful authentication (such as time-of-day restrictions)
0xC000006FUser logon outside authorized hours
0xC0000070User logon from unauthorized workstation
0xC0000071User logon with expired password
0xC0000072User logon to account disabled by administrator
0XC00000DCIndicates the Sam Server was in the wrong state to perform the desired operation
0XC0000133Clocks between DC and other computer too far out of sync
0XC000015BThe user has not been granted the requested logon type (also called the logon right) at this machine
0XC000018CThe logon request failed because the trust relationship between the primary domain and the trusted domain failed
0XC0000192An attempt was made to logon, but the Net Logon service was not started
0xC0000193User logon with expired account
0XC0000224User is required to change password at next logon
0XC0000225Evidently a bug in Windows and not a risk
0xC0000234User logon with account locked
0XC00002EEFailure Reason: An Error occurred during Logon
0XC0000413Logon Failure: The machine you are logging on to is protected by an authentication firewall. The specified account is not allowed to authenticate to the machine
0x0Status OK
