For those of you that are a MOM environment and have created a lag site, how are you overcoming the replication latency messages?

You therefore have a window of opportunity in which the deletion may be 'undone'. The deleted object may be auth restored on DC2 and thus replicated / reanimated on DC1 (and any other DC which has received the deletion).

You said "With a lag site, you ONLY have to do an authoritative restore (NTDSUTIL)". Do you mean if i delete my OU in DC in site A, all i have to do is do an autoritative restore, not on site A, BUT on DC on lag site, reboot, and dforce replication to site A ? And the non-autoritative restore will be in fact the data on the lag site, that explain your pr�vious sentence ? Waou! That's very celver !! Am I right ?

With a lag site, you ONLY have to do an authoritative restore (NTDSUTIL). Without a lag site, you must first restore the AD from backup tape ('normal' restore), which can take quite some time!!!! Then, and only then, can you do the auth restore. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of TIROA YANN Sent: Wednesday, May 18, 2005 11:46 PM To: [EMAIL PROTECTED]; [email protected] Subject: RE: [ActiveDir] AD DR - replication lag site Hello, Thanks for this interesting tips, but i didn't really understand the "behind the techno" of a lag site in case of just a deletion of an entire OU with many objects. For example,if I have AD 2003 domain with 2 sites: Site A has 2 DCs Site B has one DC and is the lag site Between 2 sites, i scheduled repl to appear every 1 week. In the situation of an OU deletion, i go to the DC i have made the deletion, and do an autoritative restore in dsmode and after rebbot, wait for replication to take place in order to repopulate all my domain with my OU restored. So what will the lag site help me in this situation ? I can understand that a lag site will help me if all my DCs in site A crashed. So i would take all informations from the lag site to be restored in site A such as "copy" my domain from the lag site by doing a dcpromo /adv, and go my freshly installed DCs on site A, and restored my whole domain. However, I think i will have more updated information by restoring from my yerterday backup than from the lag site... So, could you help me better understand the behind the techno of a lag site, i thing i misunderstand something important ;-( Thank you for your feedback. Have a nice day :-) Regards, Yann List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ ============================================================================== This message is for the sole use of the intended recipient.
