can you guys help me in getting it clear

In the windows 2008 DC, exchange 2007 context, if we re-run the adprep / forestprep on the schema master what will be the outcome, are there any issues which may occur on the Exchange &  environment, beacause of this??

What happens if I rerun adprep /domainprep ?

In the exchange 2007 media we have ADPREP is it the same what we have in Windows 2008 Server Media?  or they differ in function? Can we use any of them when they (ms) refer ADPREP?

I presume we should run x32 adprep on x32 server and x64  adprep on x64 Server, is it the rite practice?
Please correct me .

Thanks in Advance.

Adprep /forestprep extends the Schema of the Forest to enable it to support Windows Server 2008 domains. Similarly, adprep /domainprep adds values to the Schema to add Server 2008 domain support.

Don't forget that for extending the schema for Server 2008, you need to use adprep /forestprep and then adprep /domainprep /gpprep.

The schema extension procedure is additive - it adds values to the schema, but never removes them. There will be no adverse effect on Exchange. Adding 2008 writable DCs will also have no effect on Exchange, as it can communicate with 2008 DCs.

No. The Exchange schema preparation and the Server 2008 ADPrep tool are two different tools. The Exchange tool extends the schema so Active Directory will support Exchange. The Server 2008 ADPrep tool adds values which enables support for Server 2008 DCs.

That is correct. In fact, running the wrong version of ADPrep for the architecture of the server you are executing from will not work.
