Hi!

1. I'm not aware that there is limitation.
2. Which "directory partition"? Space disk is limit, AD will allow creation of new objects if it has a place to store them, at least in theory.
3. None, FSMO roles are not replicated.
4. Windows 2000 does not support application partitions, so I guess the answer would be no. I have never actually tried to replicate application partition to Windows 2000 DC.

2. It's limited by Connection speed between DCs. Basically it's got to be able to replicate the data, and if the link isn't fast enough then you don't get so far.

MS even have a nice little table of that here:

http://technet2.microsoft.com/windowsserver/en/library/d390f147-22bc-4ce3-8967-e65d969bc40b1033.mspx?mfr=true

We can scale up to hundreds of thousands with sufficient connectivity, although it would be extremely rare to encounter an organisation which includes that many.

You can adjust these limits by breaking into separate domains, that allows us to ensure that higher speed links are used between Global Catalogs for the replication of the PAS.

4. Toni is absolutely right about 4, 2000 cannot host replicas of the ForestDNSZones or DomainDNSZones application partitions. That means that a 2000 DNS Server on a 2003 Domain using those partitions for DNS Data cannot be a DNS Server (there are no functional level requirements for using the application partition).

1. Ofcourse there is no any specific limit, but ideally number of applied/Linked GPO should not exceed limit of 15 in Windows Server 2003., because it will create complexity in management, and also it will generate so much traffic on your network  and for windows 2000 9 Group Policies is optimal.

2. There is no limit in creation of objects in Active Directory, but as much as you create them more Processing power, Hard drive space, RAM and network utilization is needed. As a standard Microsoft recommended practice, you should place one DC on no more than 50 users and a dc can be use as a source dc for maximum of 15 DC for replication.

3. A Server 2003 uses multimaster model in which all DC can propogate changes in AD, However        
    Roles participation is as follows.
           Infrastructure master for replicating changes those are forest wide.
           PDC circulates Group Policy in a Domain
           Domain wide changes replicates using IP/RPC/SMTP traffic that are created using RID master.

4.  A windows 2000 DC does not have Application partitions, whereas in server 2003 there is an option of application partition which can be merged with configuration partition or some time creates it's own directory partition. For example in exchange application all information is merged in configuration partition, on the other hand DNS normally creates it's own directory partition.
