Question regarding windows Authentication and Outlook 2000

           On our domain we have two Domain Controllers running windows 2000/Active Directory.  The first domain controller let's call DC1 and the second DC2.  My question is if a user logs into their workstation and is authenticated by DC1 and DC1 then goes down or reboots and the users then launches Outlook will he/she be authenticated by DC2 or will Outlook hang?  Any help would be greatly appreciated.

Yes, DC2 will act as a backup and the users credentials can be verified by ether DC.
Are you talking about POP Mail or Exchange?

Exchange connects to which ever DC it can find. If one goes down it will look for another on to authenicate to. There should not be a problem if dns is set up right.

as far as POP Mail I do not think it would be a problem either.

It's actually Exchange and now that you mention it our DNS set up is not very stable at the moment.

Here some stuff that might help,

Do not have any external dns address on the NIC card, set those up in dns forwarders
Have each DC point to main dns as primary then themselfs as secondary
Allow dynamic updates, unless you are hostin some ones website

Good luck
