Event ID: 529 and Event ID: 537

Last Modified: 2013-12-04
I see the following logged on the security log of an xp system.      

Event ID: 529
Logon Failure
Reason: Unknown user name or bad password.
User Name: 1A
Domain: Joejj21~Bcd
Logon Type: 2
logon Process:
Authentication Package: Negotiate
Workstation Name: XPSystem

It appears to me that the domain user is logging on to this system typing the password together with the username.

I am puzzled as to why I would see Joejj21~Bcd in the Domain field instead of our domain name.  Is someone trying to access another domain or is this a bug in Microsoft?

Ive seen where one of our users types their username and password together but this shows up on the User Name field not on the Domain field.

I hope you can help me with this.

I also see Event ID 537 with the same User Name: 1A and Domain: Joejj21~Bcd when Event ID 529 occurred.

Joejj21~Bcd - is that the computer name maybe? That would be called the local domain.


No.  For example, Joej will be the user name and j21~Bcd would seem to be the password.  It would not be the name of the workstation nor the name of our domain.


Apparently, one of our users was login in from a workstation with her domain account and accidentally entered her password together with her user name on the User Name field ex. Joejj21~Bcd.  Why would Joejj21~Bcd show up on the Domain field?



Why would Joejj21~Bcd show up on the Domain field?  I have not gotten a reply on this question.  If you can help, I would really appreciate it.  If not, let me know and I will remove it.
