exch 2003 /domainprep on win 2008 DC

I have a new windows 2008 R2 domain in my forest. I need to run the exchange 2003 /domainprep on that domain; however, I cannot run exch2003 /domainprep on a win 2008 DC. How should I prep this new 2008 domain with exchange 2003 /domainprep....

?

you need to add a windows 2003 dc to that domain, run the domainprep, and remove the 2003 dc

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

endital1097, I will try your method, even though that sounds excessive. No other way to run exchange prep on the 2008 domain eh? I am going to be introducing exch 2010 soon. Can I/should I run the exch 2010 exchange domainprep on the win2008 domain? and if so, will add the necessary attributes/security to satisfy the exch 2003 domain prep?

BTW - I ran the exch 2003 domainprep from a workstation (as domain admin) on the 2008 domain, It ran successfully; however, I noticed some of the permissions on the Exchange Enterprise Server group didnt update properly (mainly the write permissions). Is this becouse I didnt run the exch 2003 /domainprep from a Domain controller?

Did you wait for ad replication?  As long as your account had appropriate permissions it should work
