ADPREP issue - Migration

Hello All,

In the middle of a migration to new DC.

I have a Windows 2000 Server SP4 running Exchange 2000 SP4

Need to extend the schema in preparation for Windows 2003 using. ADPREP from
the SBS1 CD1 I386 directory.

This is what I get next.

Anyone with experience of how to tackle this please.

H:\I386>adprep /forestprep

ADPREP WARNING:

Windows
2000 SP2 (or later).

QFE 265089 (included in Windows 2000 SP2 and later) is required to prevent
poten
tial domain controller corruption.
