MOSS People Picker cannot search Domain users

Why MOSS People Picker cannot search Domain users?
If you installed SQL server and SharePoint using local user account and not domain account, then if you are going to search domain users from the people picker, then domain user will not found from people picker.

Some work around for this:
1. Change user account for all app pool and services of SQL server and SharePoint with domain user account.
All App pool accounts(for central admin and other SharePoint web application)

2. Give access to the SharePoint database to new domain account as owner.

3. Update central admin farm credentials with new domain user account for this just need to run stsadm command.
stsadm -o updatefarmcredentials -identitytype configurableid -userlogin -password
This will update farm credentials.

4. Update SSP credentials with domain user account, Used stsadm command for change the SSP account credentails.
Stsadm.exe -o editssp -title "SSP Name" -ssplogin -ssppassword

This will update all necessary credentials for SharePoint farm, Then will get domain user from the people picker.
