hey guys, i am installing exchange on a windows 2003 machine, separarte from the dc. i ran domain and forest prep on the dc without a hitch. i can run domain prep on the exchange pc without a problem but i get this error when i try to run forest prep.

setup failed while installing sub-component microsoft windows active directory schema update with error code 0xc103798a (please consult the logs for detailed description). you may cancel the installation or try the failed setup.

Hi Chrisgmoss,

First, are you trying to run forestprep and domain prep on BOTH machines?  It only needs to be run once in the domain.

This Previous Q has a bucket load of links (which didn't work there, but at least we will see what hasn't worked)

http:Q_21610950.html

Also, here is a guide to help you better understand how it all works -> http://www.msexchange.org/tutorials/Forestprep-Domainprep-Explained.html

What I am most interested in now, is what you are actually doing.  Is the new exchange server ALSO a DC?  How many DCs do you have?  What OS are they?

Hope that helps,

OK, so your DC - that windows 2003?

Did you say that you ran exchange forestprep on that successfully?

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

Then you are all done - you only need to do it once in the domain

Install Exchange as per normal now

What do you mean?

You tried to run setup on the exchange server and it gave you the above error?

Yes you do - without it you will not be able to manage exchange attributes (like creating mailboxes for users)
