All of you ISA experts might know about the ISA Server Best Practice Analyzer. The ISA Best Practice Analyzer is used to analyze the ISA environment for potential configuration problems. The ISA Server Best Practices Analyzer is a diagnostic tool like the well known EXBPA (Exchange Best Practice Analyzer Tool) that automatically performs specific tests on configuration data collected on the local ISA Server 2004/2006 computer from the ISA Server hierarchy of administration COM objects, Windows Management Instrumentation (WMI) classes, the system registry, files on disk, and the Domain Name System (DNS) settings. You can use ISABPA for both ISA Server 2004/2006 Standard and ISA Server 2004/2006 Enterprise. If you want to know more about the ISA Server Best Practice Analyzer, read the following article.
The more recent ISA Server Best Practice Analyzer versions contain additional packages:
- The ISA Data Packager enables you to create a single .cab file containing ISA Server diagnostic information that can be easily sent to Microsoft Product Support Services for analysis.
- BPA2Visio generates a Microsoft Office Visio 2003 or Visio 2007 diagram of your network topology as seen from the ISA Server computer based on output from the ISA Server Best Practices Analyzer Tool output.
The ISA Best Practice Analyzer is a very helpful utility for ISA Administrators. Newer versions (beginning with ISABPAv5) of the ISA Server Best Practice Analyzer contain a built in version of an ISABPA to Visio utility which will help you to automatically draw a Visio diagram for your ISA Server environment. This is very helpful to document ISA Server settings.
You will need an installed version of Microsoft Office Visio 2003 Professional or Visio 2007 Professional on either the ISA Server 2004/2006 or on a separate Workstation from where you will run the ISA BPA with Visio.
It is not recommended installing Microsoft Office Visio on the ISA Server computer because of security concerns.
Installing and using the ISA Server Best Practice Analyzer is a straightforward process. Here is an overview of the process:
- Download and install the latest ISA Server Best Practice Analyzer version
- Download the newest ISA Server Best Practice Analyzer update definition files
- Run an ISA Server Best Practice Analyzer scan
- Copy the created XML file to the ISA BPA / Visio computer
- Run the BPA2VISIO tool
Downloading and installing ISA Server Best Practice Analyzer
You can download the latest ISA Server Best Practice Analyzer version from the Microsoft website. The version used while writing was 126.96.36.199. After downloading the package, start the installation process and follow the installation instructions.
Visio is needed
If you try to start the ISA Server Best Practice Analyzer to Visio tool after a successful installation, you will get the following error message on the ISA Server when Microsoft Office Visio is not installed on the computer. Please note again that it is not recommended installing Microsoft Office Visio on ISA Server computers.
Figure 1: Visio is not installed
Installing Microsoft Office Visio on the administration client
It is necessary to install Microsoft Office Visio 2003 or Visio 2007 on the administration client. For this article, we are installing Microsoft Office Visio 2007 Professional. If you want to use the ISABPA2VISIO tool for a long time period you will need an activated and licensed copy of Microsoft Office Visio Professional. If you only want to draw a diagram once, it is possible to install Microsoft Office Visio Professional without activating the software, so you can start Visio a limited number of times.

Running ISA Server Best Practice Analyzer
The next logical step is running the ISA Server Best Practice Analyzer on the selected ISA Server. For the purposes of this article we will select the Health Check scan type and name the Best Practice Report ISABPA2VISIO.
Figure 3: Start an ISA Server Best Practice Analyzer scan
After the scan has been executed and successfully finished, you can select a Best Practice Scan to view. You can see the name of the Best Practice Analyzer scan, so it is easier to find the corresponding XML file.
Figure 4: ISABPA2VISIO file name
The ISA Server Best Practice Analyzer XML file is located in the C:\Documents and settings\Username\Application Data\Microsoft\ISABPA. The name of the XML file follows the format BPAReportYYYYMMDDHHmm.xml.
Figure 5: ISA Server Best Practice Analyzer XML file
Copy this file to the administrative client PC and execute the Microsoft ISA Server Best Practice Analyzer to Visio tool and select the file to import.
After selecting the file, click Generate Diagram to generate a Microsoft Office Visio drawing of the ISA Server configuration.
Figure 6: BPA2VISIO tool
Depending on the size of your ISA Server configuration and the power of your workstation, it can take a while to generate the drawing. After some processing, ISABPA2VISIO will create and display the diagram. If you have some experience with Microsoft Office Visio, it is now possible to extend and to customize the diagram.
Figure 7: ISA BPA to Visio diagram
This diagram is based on data from the ISA Server configuration and parts of the Windows Server 2003 routing table that the ISA Server Best Practices Analyzer collects on the local ISA Server computer. This information is stored in the XML file. This created diagram is useful for visualizing the network topology of the local ISA Server computer and other servers and network devices that are viewable from the ISA Server computer. ISABPA2VISIO does not create a network diagram of your whole network. The information included in the diagram is: Servers that are published through ISA (Server- and Web server-Publishing rule), Configuration Storage servers in ISA Server Enterprise environments, and remote site networks in VPN Site to Site deployments.
Running ISA Best Practice Analyzer for Visio from the command line
It is possible to run the BPA2VISIO process from the command line. The executable file BPA2Visio.exe is located in the ISA Server Best Practices Analyzer installation directory, which is located at %programfiles%\Microsoft IsaBPA. You can open the program from the command prompt using different switches.
The command-line usage syntax for BPA2Visio.exe is the following.
BPA2Visio.exe [-f Path to XML file][-h | -? | -help] [-o Path to output file]
The following table explains the function of the command-line switches.
Generates the Visio diagram from the specified XML file.
-h -? –help
Displays the usage text.
Saves the output file of the Visio diagram in the folder specified. The output file is not saved if this switch is not included.
I like the ISA Server best Practice Analyzer to Visio tool, because as an ISA Server Consultant, I often have to implement ISA Server environments in Enterprise environments and this tool is very helpful to document the implemented ISA infrastructure. This tool is also very helpful for ISA administrators which have to document their own environment.
