5972.0. "About domains??" by CHOWDA::GLICKMAN (writing from Newport,RI) Thu May 01 1997 08:21

    Can I get some advice on setting up domains?
    
    	Customer is mainly one site with 6000 users.  The customer is
    divided up by about 10-12 codes and there are sub-codes within these 
    codes.  The codes want control over their own resources (i.e, printers,
    files,etc).  A group that maintains most of the network for this site is
    proposing the Master Domain model where they would control the logons
    in a single location and yet the other codes could still maintain
    control over their resources.  Based on what I am describing is this
    the way to go?
    
    	Also, the fellow heading up this effort for the Master Domain
    model stated that "a domain is capable of handling 15,000 user
    accounts". I wasn't sure this was a valid statement.  Can someone
    set me straight?
    
    Appreciating any responses from more experienced NT folks!
    
    Thanks.

    Master domain with resource domains sounds ok for this.
    
    There are also add-on tools (like EA) which help to partition
    administrative responsibilities even in a single domain.
    
    One does see varying numbers for the max. # of users in a domain.
    Basically, it's a function of the maximum SAM database size. Microsoft
    recommends not exceeding 40MB for it, and gives some data as to how
    much each user, group, machine etc. account needs. If you don't have
    thousands of groups, yuou could probably have quite a few more than
    15,000 users accounts.

    In NT V3.51, 15K was defined as the upper limit for the
    number of accounts and groups in a single domain.  With V4.0,
    40 mb is given as a user database size, which roughly translates
    to 26,000 accounts.

5972.3More questions...CHOWDA::GLICKMANwriting from Newport,RITue May 06 1997 09:2431
    More questions from this customer site:
    
    (1)  from .1
    >>> There are also add-on tools (like EA) which help to partition
    >>> administrative responsibilities even in a single domain.
    
    What exactly is EA?
    
    (2)  Suggestions for naming conventions
            Domains
    	    User accounts
         Can someone point me to the appropriate documentation?
    
    (3)  Suggestions for group policy  (Global vs. Local)
         Again, can someone point me to the appropriate documentation?
    
    (4)  WINS servers using TCP/IP vs. NetBEUI?
    
    (5)  Alpha vs. Intel processors -- customer is concerned that software
         for Alpha lacks behind Intel.  ie, disk utilities.
    
         Currently management is looking at using Alpha for their Exchange
         servers and Alta Vista Search engine.
          
    Appreciating any inputs.
    
    Thanks.

    Most of your questions don't really have short answers... but you
    should find most answers either on the Developer's library CD, or in a
    good NT book (like Minasi's).
    
    (1) re EA: See www.missioncritical.com
    
    (2) I think this is very much customer dependent. I would avoid any
    non-alphanumeric characters in domain names. NT usernames can contain
    just about anything - even spaces etc. If this is a homogenous NT
    environment, you could be flexible, if not, I'd stick to simpler
    usernames.
    
    (3) It's really not global vs. local - both have their distinct
    purposes.
    
    (4) Most people I know want to get rid of NetBEUI... I'd go for TCP/IP.

    You will likely use both local and global groups.  As has been stated,
    both have their distinct use in a master domain environment.
    
    A good resource for a quick overview of domains, groups, etc. is the
    Concepts and Planning Guide that comes with the V4.0 Server kit and/or
    on the V4.0 CD.

    BTW, if you read German, I can offer you studies we've written for real
    live customers... (regarding many, but not all of the areas you've
    asked about).

    Maybe this would be a good time to sell the customer some consulting? 
    MCS has a planning and install service they sell--they have certified
    folks to deliver it.
