While on the topic of distributions lists from 5.5 to 2000, there is one other support related issue that IMO is worth mentioning. Assigning "Manage" permissions to Universal Security groups aka distribution lists. In exchange 5.5 theres a nice clean GUI to give a user the ability to add/remove names from a distribution list. In Exchange 2000 the "Managed by" tab on a group is "informational only" according to <http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q281489&;> You cant use it to give a user manage permissions to the group. You have to give the user some pretty specific advanced permissions to allow them to manage a group.
I will admit though that being able to give a user/group permission to change the membership of another group without 3rd party software is a pretty nice thing.

If you use distribution lists to assign security to *any* Exchange resource (calendars, inbox, etc.), it will not work in mixed mode AD. The good news is that (as Clyde suggests) you can use another AD domain to host the USGs. The bad news is that since global catalogs have read-only copies[1] of groups from other domains, your users can no longer maintain DL membership from Outlook. Since this is exactly what we are doing, I had to develop a web based app[2] to allow users to maintain DLs after they are migrated to E2K mailboxes. Microsoft also has a freebie DL maintenance tool called AutoDL (or some such...) that has quite a bit of capabilities. [1] Not quite 100% true, but close enough for this discussion. [2] Written in Perl - I'd be happy to share with anyone who needs such a beast. -----Original Message----- From: Burns, Clyde [mailto:[EMAIL PROTECTED]] Sent: Monday, October 07, 2002 8:03 AM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] Exchange 5.5 upgrade to 2000 Jennifer, another thing to think about migrating from Exchange 5.5 to Exchange 2000. One of the caviats that you are going to run into is distribution lists in your Windows 2000 mixed mode domain (or lack of). The ADC creates Universal Security groups in windows 2000 from distributions lists in Exchange 5.5. These type of groups arent available in w2k mixed-mode. Which can cause havok on public folders IF you use distribution lists to give/restrict access to public folders. <http://support.microsoft.com/default.aspx?scid=kb;en-us;Q316886&sd=tech> is a good jumping off point to read about this. In your case of not being able to go native in w2k you may have to setup a temporary native mode child domain for your distribution lists to live in.

When one of our satellite offices was still in mixed mode they were running Exchange 5.0 on and NT4.0 box. This box was also a BDC (formerly the PDC until AD servers were introduced. I recommend you upgrade your 5.5 box to SP6 (if it's not already there.) Set up an ADC between the Exchange 5.5 box and one of your AD DC's and allow replication to begin. Then when you are ready --- install a separate (preferably new/clean box) Win 2K Exch 2K server into that exchange site (remembering to run setup with the /ForestPrep and DomainPrep switches separately) - migrate your mailboxes over to the 2K box decommission the 5.5 box ---- and switch to Exchange Native Mode (which is different than Win2K [AD] NATIVE MODE). Then when you are sure you have no remaining NT 4.0 domain controllers --- switch to Windows 2000 Native Mode. Craig Craig P.

We currently have e5.5 and plan to upgrade to e2k next month. (since we aren't in native, we can't do a migrations using the adc - right?) can i setup my new exchange server (offline) with w2k and e5.5 and then upgrade to 2000 then take down the production 5.5 and put the new 2k box into production? any gotchas? can i do this? thanks!! ------------------------------------------ Thank you Jenn Fountain 215.712.5156 List info : http://www.activedir.org/mail_list.htm List FAQ : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/mail_list.htm List FAQ : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/mail_list.htm List FAQ : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/mail_list.htm List FAQ : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/mail_list.htm List FAQ : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
