Globa catalog and logon process

I have one domain, so I should have only one global catalog server that determines group membership during a logon process. I also think the global catalog responds to the service requests.

My network windows 2000 domain has 05 domain controllers, and my question is:
is there only one DC(the one that is GC) out of 5 that responds to the service request and handles the logon process?
what abou the roles of the rest of 04 DC?

thanks

Hi.  You should have at least one GC per site.  That is the minimum, so if you can, you should at least have two.
As for the other roles, the infrastructure master should be on its own.

How many servers do you have total? -- not just DCs.

The GC handles the logon request if the user is logging on  with the UPN, or if you are in a multi-domain and the user is logging on initially to receive the Universal Group membership.  Otherwise, any of the DCs can handle the requests.

I still can use W98 to logon to the native mode domain? or do I have to install WINS?

Hi.  Native mode refers to Domain Controllers.  The 98 machine should be able to logon to the domain--it just needs the AD client: http://www.microsoft.com/windows2000/server/evaluation/news/bulletins/adextension.asp

You shouldn't have to run WINS.

If you are having problems with legacy clients, you might also want to check your ad security policies.  Also, I don't know the extent of the issue, it is common to require kerberos.  If you have such a situation and cannot make the change for requiring kerberos, for the 98 machines, you might want to take a look at the following: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q305144
