RE: [ActiveDir] what to do with DMZ servers

Title: Message

Technically, we have 1 person. But he's a Director level, so he has some weight. It helps that he's also spent a lot of time with the sysadmin lead (me) and the network engineer (sits next to me). One of the best aspects of our company is that we've all worked together for a relatively long time - I'm the newest of the 3 of us, and I've been here just under 4 years.   Sounds like it worked out in the end for you, though. -------------------------------------------------------------- Roger D.

I'd assume any security specialist worth employing would agree with the separate domain concept.   Roger -------------------------------------------------------------- Roger D.

(Assuming that the Servers in the DMZ are already away from the in-house domain)   If before the upgrade none of the servers needed AD or access to your in-house domain, why would you want them to have it after the upgrade?    J Just thinking semi-logically...     Thanks,   Raymond McClinnis Network Administrator Provident Credit Union   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Roger Seielstad Sent: Thursday, July 10, 2003 7:19 AM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] what to do with DMZ servers   It would help if you determined what was going to be public access (via DMZ or otherwise) and determine the needs of the applications there.   The other option we've been talking about is AD Application Mode (ADAM) from Microsoft.     -------------------------------------------------------------- Roger D.

Option2:  Create a separate forest for the DMZ servers and create a one-way trust between our two forests.  Option3:  Stand alone DMZ servers not joined to any domain. All other options: ??????????????????????????????   Your suggestions are greatly appreciated!   Is there even a need to hook DMZ into AD?  I've heard MS talk about needing AD for apps like Sharepoint Portal...     Joe Pelle Systems Analyst Information Technology Valassis / Targeted Print & Media Solutions 35955 Schoolcraft Rd.   Livonia, MI  48150 Tel 734.632.3753      Fax 734.632.6240 [EMAIL PROTECTED] http://www.valassis.com/   This message may have included proprietary or protected information.  This message and the information contained herein are not to be further communicated without my express written consent.
