Installing Brazos Step by Step

The installation of Brazos is reasonably simple, as it's distributed in a self-extracting installation file, that is, you have only to download the distribution file into the desired directory, and double-click on the executable archive in order to install automatically.

However, along the installation, it's necessary to give some information about the machine where the Brazos has been installed. Because of that, you need the administrator privileges to install this software.

On the setup program, there are three types of installations: "Typical", "Custom" and "Minimal". The "Typical" type installation will install the most commonly used components of the system. The "Custom" installation allows the installer to chose which components will be installed and the "Minimal" will only install the Brazos Remote Service and make appropriate registry changes. Usually, the "Typical" or "Custom" installation is necessary only on a single machine in the cluster, while the others machines need only the "Minimal" installation.

Along the installation process you will be prompted to enter with some information of your system:

	First, two base address for multicast communication is required. This address consists of the first three bytes of a valid IP multicast address in standard dotted format. It's good to remember that the valid multicast addresses are between 224.0.0.0 to 239.255.255.255. An example of a valid address in this case is: 234.5.6 (remember, only the first 3 bytes);
	Following, it's necessary to give the port number where the Brazos will connect the 'Remote Access Service' and the user interface. We suggest any free port, and so, a high number like 1270;
	Finally it will be necessary to enter with a 16-character string that will generate a key that will be used by the Brazos encryption routines in order to provide security to user. ATTENTION!: This key (string) must be the same for all the machines on the cluster, because if it's not the case, the remote will not start as Brazos will not be able to decrypt correctly!!!

ATTENTION!: At the end of the installation it's necessary to make a small change of files, because there is a little problem on the Brazos installation. The fact is that Brazos installs a DLL (MFC42D.DLL) on the directory \WINNT\SYSTEM32, but the GUI uses the MFC42.DLL DLL (which is a little bit outdated), provoking an error when the GUI brazos.exe is executed. There are two solutions: 1) rename the file MFC42D.DLL that Brazos installs to MFC42.DLL or 2) install a new version of this DLL. New versions of Netscape (version 4 or later) or MSOffice (97 or later) also installs this DLL, with the difference that they are more updated and so they work correctly.
