Migration ?? window 2000 and exchange 2000
I have read some information from Msft TechNet ,"Exchange 2000 in 6 Step",page 13, "Ensure that one domain in the forest is a windows 2000 native-mode domain. This domain will support universal groups".
I am confusing above concept about exchange 2000 migration as bellow,
I have migrated NT Domian to Window 2000 ADS in mixed mode, We have plenty of distribution list with
exchange 5.5/NT BDC. Right now, we are planning to migrate Exchange 5.5 to Exchange 2000, Do I have
to switch this mixed mode (I mean Win2k/ADS) to native mode, in order to make "Distribution List" in
Exchange2K function as usual?

ADC (Active Directory Connector) will try to migrate distribution lists into universal groups - if the domain/forest is not in native mode, the DL's will be migrated as contact objects. universal groups only exist in Win2k native mode. Therefore, yes, to have your forest see all the DL's and send mails to them, they must become universal groups. Remember, the GAL in Exchange 2000 is Active Directory itself -- no more Exchange GAL. Change the ADS mode to native, but leave the Exchange as mixed mode if you want it to continue to comunicate with the existing 5.5 servers. Good luck and have fun.
How many domains are involved? If only one, it doesn't matter if you switch to native mode or not: global groups are sufficient for a single domain. But if there are more domains (single or multiple trees), at least one has to be switched to native mode to support universal groups.

As you described that mixed mode/global group is sufficent to handle the DL. The native mode is for Root domain + child domain. ie, aaa.com + state.aaa.com + sales.state.aaa.com..., Therefore I can run ADS/mixed mode first in Single root domain migration from Exchange 5.5, then switch to ADS/native mode if there were more child domain join to root domain. Am I correct ?

No.
Distribution list has nothing to do with Active Directory being in mixed or native mode.
> to make "Distribution List" in Exchange2K function as usual?
To migrate existing Exchange 5.5 Directory information to Windows 2000 Active Directory ( which Exchange 2000 uses), use "Active Directory Connector" during the migration phase. You should read more detailed documentation from Microsoft site on how to use it.
