Ldap error with Exchange 2003 1

[RichardHuang]

Hello,

I keep getting the ldap error message from our Exchange 2003 server. It tries to contact the DC that I have already demoted. The event log info is as below. Does anybody have any idea on this? Thank you for your help.

Under your recipient update services, either the enterprise or domain RUS has an invalid domain controller listed. Double click each one and verify the "windows domain controller" setting.

Thank you so much. You are right. I changed the domain controller setting there.
