Account mapping to SID error

I am trying to get rid if the following error in my event log:

Event Type:      Warning
Event Source:      SceCli
Event Category:      None
Event ID:      1202
Date:            4/8/2010
Time:            5:24:20 AM
User:            N/A
Computer:      CHISMS1
Description:
Security policies were propagated with warning. 0x534 : No mapping between account names and security IDs was done.

Advanced help for this problem is available on http://support.microsoft.com. Query for "troubleshooting 1202 events".

Error 0x534 occurs when a user account in one or more Group Policy objects (GPOs) could not be resolved to a SID.  This error is possibly caused by a mistyped or deleted user account referenced in either the User Rights or Restricted Groups branch of a GPO.  To resolve this event, contact an administrator in the domain to perform the following actions:

1.      Identify accounts that could not be resolved to a SID:

From the command prompt, type: FIND /I "Cannot find"  %SYSTEMROOT%\Security\Logs\winlogon.log

The string following "Cannot find" in the FIND output identifies the problem account names.

 After looking at the winlogon.log it appears to be my administrator account for  this member server. Due to security requirments this account has been renamed. Is their a way to clean up this error ? Here is part of the winlogon.log file. Foe sum reason this site would not allow me to attach the file when I click on "add file"
