swing migration event log errors. Event ID: 1202

I am performing a swing migration from sbs2k to sbs2k3 and have gotten to
the point where I've "swung" everything over to the new server and just need
to now finish installing ths sbs2k3 components. However, I have three
errors in the event log that somewhat puzzle me.. Can anyone shed some
light on them for me? Can I ignore these? [[brackets are my comments]]

Thanks!!!!!

The help I receive here is invaluable!


[[I typed in the "FIND /I "Cannot find"
%SYSTEMROOT%\Security\Logs\winlogon.log" command and it returned about 20
lines all referencing iwam_netserver and iusr_netserver ]]
Event Type: Warning
Event Source: SceCli
Event Category: None
Event ID: 1202
Date: 6/8/2007
Time: 12:58:17 AM
User: N/A
Computer: NETSERVER
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.

Example: Cannot find JohnDough.

In this case, the SID for username "JohnDough" could not be determined.
This most likely occurs because the account was deleted, renamed, or is
spelled differently (e.g. "JohnDoe").

2. Use RSoP to identify the specific User Rights, Restricted Groups, and
Source GPOs that contain the problem accounts:

a. Start -> Run -> RSoP.msc
b. Review the results for Computer Configuration\Windows Settings\Security
Settings\Local Policies\User Rights Assignment and Computer
Configuration\Windows Settings\Security Settings\Local Policies\Restricted
Groups for any errors flagged with a red X.
c. For any User Right or Restricted Group marked with a red X, the
corresponding GPO that contains the problem policy setting is listed under
the column entitled "Source GPO". Note the specific User Rights,
Restricted Groups and containing Source GPOs that are generating errors.

3. Remove unresolved accounts from Group Policy

a. Start -> Run -> MMC.EXE
b. From the File menu select "Add/Remove Snap-in..."
c. From the "Add/Remove Snap-in" dialog box select "Add..."
d. In the "Add Standalone Snap-in" dialog box select "Group Policy" and
click "Add"
e. In the "Select Group Policy Object" dialog box click the "Browse" button.
f. On the "Browse for a Group Policy Object" dialog box choose the "All" tab
g. For each source GPO identified in step 2, correct the specific User
Rights or Restricted Groups that were flagged with a red X in step 2.
These User Rights or Restricted Groups can be corrected by removing or
correcting any references to the problem accounts that were identified in
step 1.
