Forestprep fails during AD update on Windows 2000 to Windows 2003. Problem with x500uniqueidentifier in sch18.ldf.
Posted on 2004-09-06
How do I get around this adprep /forestprep error where forestprep fails when updating sch18.df on line 275. See error log output:
Entry DN: CN=x500uniqueIdentifier,CN=Schema,CN=Configuration,DC=csb-dom,DC=cathedralschool,DC=net
Add error on line 275: Unwilling To Perform
The server side error is "Schema update failed in recalculating validation cache."
An error has occurred in the program
I have run dcdiag and netdiag and all is fine. I have also checked AD using ASDI and found no damaged LDAP entries for Exchange 2000. I'm running Windows 2000 sp4 and Exchange 2000 with sp3.
