exchange server and Schema Master

[Lus]

hi, here i have a senario about moving schema master role and users E-mail Address.

we have 2 DC as shows below :

1- W2k Sp4 : DC, DNS, IIS, Exchange 2003 and hold PDC,RID,Infra,Schema master Role.

2- W2K3 Sp1 : DC, DNS holde DN estructure

domain name : xx1

we wanted to reinstall W2k, OS for some reasone so i designe a plan for moving exiting service of w2k to w2k3.

i transfer PDC, RID, Infra structure role to W2k3 successfully, but i could not move Schema master role

i use GUI tools and NTDSUTIL.

in GUI tools change buttom was disable ? i do not know why ?

and by using NTDSUTIL i get error.

after reinstall w2k OS get back RID role and seize Schema master on w2k.

and expanding schema role for using Exchange. after restore exchange back up, all users email box that relate to domain name (xx1) was restore but their seconde mail box that was build manually did not.

i mean, their mail box was create but in their "Address mailbox" in active direcotry user propertise did not create or restore their second mail address ?

any idea ?
