✔ Best Answer
Back up your data, dig out your install CDs, bite the bullet, and reinstall from scratch. You can't upgrade from 32-bits to 64-bits or the other way round.

There is no upgrade path from 64bit to 32bit. You will have to format your drive and install 32bit.

But if you don't tell anybody, you might be able to edit your registry

1. Access HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
2. Create a new DWORD entry called LmCompatibilityLevel
3. Modify the entry and set the value to 1
4. Reboot

But I didn't tell you how to do it.

Start button, All Programs, Anytime Upgrade if you want to stay 64bit ONLY. Microsoft made it easy for you. For 64bit to 32bit, SORRY no easy way.
If you just doing a home network or a pier to pier small office network, this is not necessary but for a server environment professional is necessary but I do not know that you cannot use 64bit Professional even if everyone else is on 32bit.

You have to be a little bit crazy to keep you from going insane.

If you have a fully working 64 bit OS then why not upgrade to a domain version of 64 bit?

Are you sure what you mean by an Active Directory Domain?

Hang up and live.
