DDW Server system requirements - BlueCat Address Manager - 9.0.0

Address Manager Administration Guide

BlueCat Address Manager

A DDW server is a necessary component of managing a Windows DNS or Windows DHCP server with Address Manager.

The following table shows the minimum system requirements for the Windows server on which you wish to install the DDW software.
Component Requirement
CPU(s) 2.5 GHz
Memory 8GB minimum; 16GB recommended
Free Disk Space 5GB minimum; additional 2GB per Managed Windows server
Operating System Windows Server 2012 R2, Windows Server 2008 R2
Software framework Microsoft .NET 3.5 (Windows Server 2012 R2 only)
Note: Microsoft .NET Framework 3.5 must be installed and enabled as a Windows feature on servers using Windows Server 2012 R2 prior to installing BlueCat Address Manager for Windows Server (DDW) v8.2.0 or greater.

Supported Windows Operating Systems

Address Manager can manage the following versions of Windows Server:
Version Type Platform
Windows Server 2012 R2 Standard 64-bit


TCP port 10042 and TCP/UDP port 10045 must be open on the DDW server and on any firewalls between Address Manager and the DDW server for Address Manager to connect to and communicate with the DDW server.
Note: The DDW Server installer provides the option to setup firewall rules corresponding to TCP port 10042 and TCP/UDP port 10045 on your behalf, or you can configure the firewall manually after installation.

In addition, well known TCP port 135 should be open on managed Windows DNS/DHCP servers for Remote Procedure Call (RPC) communication between the Windows Servers and the DDW Server (DDW always acts as the RPC client in communication with the remotely managed Windows servers).

Communication between Address Manager and the DDW Server

Protocol Destination port/range Destination Source port/range Source
TCP 10042 DDW Server 1024-65535 Address Manager
TCP/UDP 10045 Address Manager 1024-65535 DDW Server

Communication between the DDW Server and Managed Windows servers

Protocol Destination port/range Destination IP Source port/range Source IP
TCP 135 Managed Windows server 1024-65535 DDW Server
TCP 49152-65535* Managed Windows server 1024-65535 DDW Server
Note: *This range may vary depending on your Windows configuration. For more information, refer to the following knowledge base article on Microsoft Support: http://support.microsoft.com/kb/154596

DNS and DHCP RPC Services

DNS RPC and DHCP RPC service must be enabled.

Time Synchronization

Ensure that the system times on Address Manager and the DDW server are synchronized. Preferably, the system times should be synchronized using a Network Time Protocol (NTP) service. Address Manager can be configured to provide NTP service. For more information, refer to Network Time Protocol.

Computer Browser Service

As part of the installation process, you are asked to enter account information for the user account representing the DDW service. If the Computer Browser service is running and is not blocked by an on-board firewall, you can browse for the user information. If the Computer Browser service cannot be running for any reason, you can type the user information statically. For more information, refer to Creating a DDW server.
Note: On Windows Server 2012 R2 or earlier, you might need to configure the service to run.
