Microsoft Active Directory Topology Diagrammer

Okay… so here’s a tool which’s not that common but actually deserves some attention.

The ADTD utility is a superb small tool which’s really helpful in the event you’re assigned a task at a customer who has no idea where the documentation of their AD DS is or if they even got such.

ADTD will give you the possibility to make a diagram of your Active Directory Topology including Exchange specific details. You’ll also get the possibility to add information about domains, sites, OU’s, GPO objects (including the names and where they’re linked in the OU hierarchy), servers, DFS-R and quite a few other things.

If need be it can even draw partial details of your environment like information regarding a specific domain or site.

Prerequires

  • First of all you need to grab a copy of Visio 2003 or newer and install it.
  • Secondly go to the link in the bottom of this article and download and install the ADTD utility.

Main Window

Once fired up, you’ll be met with the application window as shown in Figure 1.
In the Server/Domain textbox you need to enter an IP address of a Global Catalog DC or the domain name.

When ADTD launches it’s initially placed at the first of the seven tabs, which contain settings regarding Domains.

Domain Tab

  1. If you wish to get a drawing of your domains you must first check the “Draw Domains” checkbox.
  2. Then specify which part of the Active Directory structure you wish to have drawn by selecting it in the dropdown box.
  3. Under “Domain Details” you need to specify from where the ADTD utility needs to gather its information. You can choose either DNS or GC. Personally I recommend going with DNS as a first choice.
  4. Under “Trusts” you must select what kind of information you wish to gather about incomming and outgoing trusts in your AD DS. Please notice the checkbox for gettings details for trusted AD domains.
  5. Under “Users” you simply get the ability to count the amount of user accounts currently present in each domain.
    Beware that this takes quite some time and may cause ADTD to appear like it’s unresponsive.
  6. Finally “Global Catalog” simply gives you the ability to detect which DC’s are also GC’s.

OUs Tab

  1. If you wish to get a drawing of your OU structure you must first check the “Draw Organizational Units” checkbox.
  2. Then specify which part of the OU structure you wish to have drawn by selecting it in the dropdown box, under the “Draw OUs” section.
  3. If you want to limit the amount of OU levels you want to dive into, you get the possibility by enabling “Limit OU Levels to:” under “OU Details”.
    Leaving it unchecked will render all OU levels.
  4. Under “GPO Details” you get a very cool option to add GPO names to the OU visio drawing.
    By enabling this checkbox you will not just get a OU diagram showing that a GPO is linked to a specific OU but you’ll also get the actual GPO name.

Sites Tab

  1. If you wish to get a drawing of your site structure you must first check the “Draw Sites” checkbox.
  2. Then specify which part of the site structure you wish to have drawn by selecting it in the dropdown box, under the “Draw Site” section.
  3. Under “Site Links” you need yo specify if you want to check for (and if found then draw) IP and SMTP Site Links.
    Normally you’ll be fine with having only “IP Site Links” checked.
  4. Under “Replication Connections” you can specify if you want both intra- and intersite connections added to the drawing.
    You also get to specify whether you want more details or not by checking the “Detailed Replication Connections”.
    Finally you have the possibility to leave empty sites out of the drawing by checking the “Suppress empty Sites”.
  5. Under “Subnets” you get the option to include information about subnets at each site.
  6. Under “Site Links containing >=2 Sites” you can select to have all possible connections drawn.
    Whether you need this or not is probably based upon whatever problem you’re currently trying to solve.

Exchange Tab

  1. If you wish to get a drawing of your Exchange structure you must first check the “Draw Exchange Organization” checkbox.
  2. Under “Message Connectors” you must specify the connector types you wish to include in the drawing.
    Normally you can probably do with having just SMTP and X.400 selected but there’s a few other interresting entries you might need in your situation i.e Lotus Notes Connectors if Lotus Notes is deployed in the environment.
  3. Under “Replication Connectors” you’ll find the possibility to include Exchange 5.5 site to site connectors.
    You only need this if you got Exchange 5.5.
  4. Under “SMTP Connectors” you can specify to get detailed informations regarding the SMTP Connectors.
    Whether you need this or not depends mostly on your current situations.
  5. Under “Mailboxes” you’ll get an option for counting the mailboxes at each Exchange Server.
    Beware that this takes quite some time and may cause ADTD to appear like it’s unresponsive.
  6. Under “Servers” you get the option to “Suppress Domain Controllers”. Selecting this will display ONLY Exchange Servers at the Exchange visio drawing.
  7. Finally there’s a “Drawing options” section where you’ll get the possibility to select whether you want Exchange servers listed in Exchange RoutingGroups or in AD Sites.
    Whether you want the former or latter depends mostly on what you’re currently trying to accomplish.
    Beware that this option takes quite some time and may cause ADTD to appear like it’s unresponsive.

Applications Tab

  1. If you wish to get a drawing of your Application Directory Partitions you must first check the “Draw Application Partitions” checkbox.
  2. Then specify which part of the application partition structure you wish to have drawn by selecting it in the dropdown box, under the “Draw Application Partitions” section.
    If you’re drawing these visio documents because you need some detailed informations regarding an AD DS environment, I’d recommend that you draw the entire application partitions structure, since you’ll be able to quickly identify whether or not you have more applications partitions than the default “ForestDNSZones” and “DomainDNSZones”.

DFS-R Tab

  1. If you wish to get a drawing of your DFS-R (Distributed File System Replication) structure you must first check the “Draw DFS Replication” checkbox.
  2. Then specify which part of the Active Directory structure you wish to have drawn by selecting it in the dropdown box, under the “Draw DFS Replication” section.

Servers Tab

  1. If you wish to get a drawing of your Domain Controllers you must first check the “Draw Servers” checkbox.
    This will not draw anything else than DCs.
  2. Then specify which informations regarding your DCs you wish to include in the drawnings by selecting one or more of the checkboxed, under the “Draw Servers” section.
    • The “Include Server Version” will include the version of the OS installed at the DC.
    • The “Draw FQDN Server Names” will enter server names as Full Qualified Domain Names instead og just their hostname.
    • The “Colorcode Server per Domain” will groups DCs in color groups depending on which domain they’re part of.
      If you have a Single Domain Forest this option will not give any value for you.

Discover Button

Once you’re satisfied with your selections you simply hit the “Discover!” button
Once the discovering is completed you’ll get a status message like in Figure 8.

Draw!

Now, with the discovering process complete, simply hit the “Draw!” button and wait for the magic to happen.
Visio opens and adds the different components to the canvas, but the drawing is not completed before ADTD says “Drawing Complete!” in the status bar.
The drawings are automaticly saved in the Documents folder of your current user account.
