With the demise of isatools.org a few years ago, many ISA Server and Forefront TMG 2010 administrators have reached out to me to ask where they can find the ISAinfo tool that was previously found on that site. If you’re not familiar with ISAinfo, it was a great utility used for viewing the ISA or TMG configuration by parsing the configuration export. This tool is tremendously useful for providing support, as it includes all of the information required to provide context for troubleshooting. In addition it is an excellent documentation tool.
So, if you’re looking for a reputable location from which to download this tool, look no further. I’ve placed the isainfo.zip file along with the checksums for file verification on my public OneDrive. Enjoy!
Just a few months ago I wrote about the beta release of Fastvue’s TMG Reporter v3.0, which includes some compelling new features that TMG firewall administrators are sure to love. Today I’m happy to announce that TMG Reporter 3.0 is now generally available. If you’re still using Forefront TMG 2010 in production, you’ll certainly want to check out the latest features TMG Reporter v3.0 has to offer. Site Clean is sure to impress! Head over to the Fastvue blog for more information.
I’m a huge fan of the Fastvue TMG Reporter advanced reporting solution. If you’ve spent any time at all with the native Forefront TMG 2010 reporting tools, you know they are, as my British friends say, “rubbish”. While it is possible to configure Forefront TMG 2010 to log to an external SQL server and create your own reports, a better alternative is to use Fastvue TMG Reporter. They’ve already done all the hard work for you! Also, TMG Reporter from Fastvue works with TMG when configured to use an external SQL server, so you get the best of both worlds!
Recently the fine folks at Fastvue announced a sneak peak at their latest update to TMG Reporter in v3.0 Beta. This latest release includes a bunch of great new features, including the following:
- Site Clean – This provides a way to clean up a lot of noise from your activity reports by consolidating related requests (e.g. analytics and CDN requests).
- Private Report Sharing – Create a report for an individual or group and prevent them from accessing any other report data.
- AD Security Group Filtering – A must have for searching activity reports!
- Export to CSV for Reports and Report Tables – Great feature for detailed, granular data analysis offline.
- Filter by Firewall Server Name or IP Address – This is essential for enterprise customers managing multiple TMG firewalls across the organization.
The latest release also includes Gantt Bars for Activity Reports, changes to the Productivity Dashboard, inclusion of search terms in User Overview reports, an updated Alerts interface, and improved data visibility. In addition, v3.0 includes memory usage improvements and the usual bug fixes and miscellaneous minor improvements.
Be sure to download Fastvue TMG Report v3.0 Beta today!
Recently I’ve seen a lot of chatter on the Internet about downloading key generators and crack codes for Forefront Threat Management Gateway (TMG) 2010. Yes, it is true that since Microsoft announced the end of life/end of sale for Forefront TMG 2010 they are no longer selling processor licenses for it. However, downloading a keygen or obtaining software licenses some other way is not only illegal, but dangerous.
A better (and legal!) alternative is to purchase Forefront TMG 2010 from a reputable Microsoft OEM partner. Microsoft OEM partners are still selling Forefront TMG even today. And coincidentally, I just happen to work for one! That’s right, Celestix Networks is still selling their MSA hardware appliance solution with Forefront TMG 2010. So, if you still wish to deploy a new instances of TMG 2010 and don’t currently have the necessary licensing, Celestix Networks can help you out.
DirectAccess is a compelling remote access solution that provides seamless and transparent, always-on, bi-directional remote corporate network connectivity for managed Windows clients. In Windows Server 2008 R2 and Forefront Unified Access Gateway (UAG) 2010, the DirectAccess server had to be configured with two network adapters, with the external network interface configured with two consecutive public IPv4 addresses. Many security engineers were understandably concerned about exposing a domain-joined Windows server directly to the public Internet, which limited the adoption of the technology. Beginning with Windows Server 2012, DirectAccess is integrated in to the operating system and provides more flexible network configuration. DirectAccess can now be deployed behind an existing edge security solution performing NAT, and even supports single-NIC configuration.
The Forefront TMG 2010 firewall is an excellent choice to provide essential protection for the DirectAccess workload. When DirectAccess is deployed behind a NAT device, the only firewall port that needs to be opened is TCP port 443 (HTTPS).
When publishing DirectAccess with TMG, it is important to use a server publishing rule and not a web publishing rule. To publish DirectAccess, open the Forefront TMG 2010 management console, right-click Firewall Policy in the navigation tree, and then choose New Non-Web Server Publishing Rule.
Provide a descriptive name for the rule, enter the IP address of the DirectAccess server, choose HTTPS Server for the protocol, and then select the network interface on which to listen for these requests.
To ensure the proper operation of Receive Side Scaling (RSS) on the DirectAccess server, it is recommended that the server be configured to use TMG as its default gateway and to configure the publishing rule on TMG using the option Requests appear to come from the original client.
Also, TMG does not support load balancing for server publishing rules, so it is not possible to deliver traffic to multiple back end servers using TMG. For high availability and to provide for scalability, it is recommended to configure load balancing for DirectAccess using NLB or an external load balancer (recommended) and publish the virtual IP address (VIP) using the steps described above.

When performing POODLE attack mitigation on the Forefront TMG 2010 firewall by disabling SSL 3.0, you may encounter a scenario in which TMG’s SQL services fail to start after a reboot.
Looking through the Windows system event log you may see an error message logged by the Service Control Manager with event ID 36871 which states:
A fatal error occurred while creating an SSL server credential. The internal error state is 10013.
In addition you may also see an error message logged by the Service Control Manager with event ID 7024 which states:
The SQL Server (ISARS) service terminated with service-specific error %%-2146893007.
This can occur when SSL 3.0 is disabled at the same time that TLS 1.0 is also disabled. Even though TLS 1.1 and 1.2 might be enabled, TMG requires that TLS 1.0 specifically be enabled for SQL server services to function properly when SSL 3.0 is disabled.
To resolve this issue, enable TLS 1.0 Server in the registry by changing the value of Enabled to 1, as shown here. If these registry keys do not exist, create them.
Restart the server for the change to take effect.
