Report on AD Accounts?

You could create a custom query in ADUC, or I'd suggest using PowerShell. Using the new R2 AD cmdlets you could do something like this:

[datetime]$from="1/1/2009"
[datetime]$unto="1/1/2010"
get-aduser -filter {WhenCreated -gt $from -AND WhenCreated -lt $unto} -Properties WhenCreated | Sort WhenCreated | Select DistinguishedName,Name,WhenCreated

Or you could use the free Quest cmdlets:

get-qaduser -SizeLimit 0 -CreatedAfter "1/1/2009" -CreatedBefore "1/1/2010" | Sort WhenCreated | Select DN,Name,WhenCreated

An advantage of using PowerShell is that you can do all sorts of things with this information. From saving it to a file, exporting to CSV or XML, creating an HTML report and much more.

You can easily pull this information from an ADO query scoped at the directory where the users reside.  Look here for more info

ex:

"(&(objectCategory=person)(objectClass=user)(whenCreated>=20080101000000.0Z))"
