Synchronize migrated objects utility and workstation updater will not accept credentials
Microsoft's security configuration wizard is known to cause this problem.
Check the Domain Controller policy and look at this setting:
Computer Configuration|Windows Settings|Security Settings|Security Options
Network security: LAN Manager authentication level Send NTLMv2 response only\refuse LM & NTLM
Network security: LAN Manager authentication level Send NTLMv2 response only\refuse LM
NDS Migrator uses NTLM authentication and setting the authentication level to refuse NTLM will call the authentication to fail.
