Change vbscript to ldap query across two domains instead of just one

I have a script that I use to query for servers on our domain. I need this same script to get servers from my domain (dom1) as well as another domain (dom2). I've attached the LDAP query section, but I have little LDAP experience and am not sure how to ammend the code to make it work with both domains.

Set objRootDSE = GetObject("LDAP://RootDSE")
objCommand.CommandText = "SELECT name, operatingSystem " &_
	"FROM 'LDAP://" & objRootDSE.Get("defaultNamingContext") &_
	"' WHERE objectClass='computer' AND (operatingSystem='Windows Server 2003*' OR operatingSystem='*2000 Server*')"
Set objRootDSE = Nothing
