RE: [ActiveDir] multiple sites DNS question

[Roger Seielstad]

Title: Message

Actually, DNS traffic in general is fairly light - I've run orgs in which 80+ physical locations ran off 2-3 DNS servers, across WAN's, without issues. Technically, there's no need for more than 2 DNS servers in a lot of AD scenarios.   Keep in mind that a client queries DNS for GC and DC information, which is really just a few packets of data. The authentication and GC use will still be local.   Replication delay is only an issue if clients are pointing to different servers. If everyone points to the same server, its not an issue.   Roger -------------------------------------------------------------- Roger D.

Now, these local dns servers can point to tha ROOT SERVER.   Designing wise this is how it shuld be done.   CLIENT -- LOCAL DNS -- MAIN DOMAIN CONROLLER.   Cheers, Mohammed Athif Khaleel -----Original Message----- From: Santhosh Sivarajan [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 10, 2004 4:48 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] multiple sites DNS question "Pointing to tha main Dc is not recommended"   Can you explain why?     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, February 10, 2004 1:13 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] multiple sites DNS question   Dear Montano, The local computers must and shud always point to the DNS server of their site. Like in SITE 2, lOCAL DNS shuld be DC3.   Pointing to tha main Dc is not recommended.   Cheers, Mohammed AThif Khaleel -----Original Message----- From: Montano, Greg [mailto:[EMAIL PROTECTED] Sent: Monday, February 09, 2004 6:44 PM To: [EMAIL PROTECTED] Subject: [ActiveDir] multiple sites DNS question Hi all,   I have 1 AD domain spread over 3 sites   Site 1 - DC1, DC2 Site 2 - DC3 Site 3- DC4, DC5   all DCs are global catalogs   DC1 holds FSMO roles     What is the prefered way to set up local computers primary and secondary DNS for site 3 DCs?   should they all point back to DC1?  or to each other?   Thanks   ----------------------------------------------------- This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom/which they are addressed.
