Unable to install sp1 of Microsoft forefront TMG 2010

Hello Folks,

We are using Microsoft forefront TMG 2010 in our company.

I tested installation of Service pack 01 on virtual pc and everything works fine. But when I started installation on actual server, I end up with the following error.

Microsoft Forefront TMG service Pack 1 Installation Wizard

A connection to the specified configuration storage server could

not be established. This may be because the local computer needs

to be added to the Managed ISA Server computer set.

Error code – 0x8007203a.

Error description = The server is not operational.

                                                                     OK

The server machine contains Windows 2008 R2 with Forefront TMG 2010 and two network cards, one for internal and one for external connectivity. The virtual environment is same like the actual,l but nothing happens while doing the upgrade over there. I need a quick work around in this regard as it makes me unable to connect my internal network to the internet.

I m planning to restore the backup containing without SP 1 contents, but eventually I have to install service pack to patch the system. So kindly share, if someone has some solution for successful installation of Service pack 1.

Thanks.

Hi,

I see that you are using Microsoft forefront TMG 2010. Firstly, try to check whether the DNS is correct using the Microsoft Website.

The error you are facing is probably a DNS error so check in the above website and make sure the DNS is fine. Now restart and try installing again. If you face the problem again then try the dcdiag tool. If that also does not work you may try the exchange best practice analyzer.

Hope this information helps you.

Hello,

I read one of the experts blog for finding this solution, after that I asked another expert who works in my local area about this solution. Now the solution is like:

You have to check some criteria for installing MS Forefront TMG service, first install a tool called ldp on Isaserver2.contoso.com, open the ldp and connect to Isaserver1.contoso.com on port 2172. Now try to ping Isaserver1.contoso.com using Isaserver2.contoso.com. if that ping is successful than you can install it properly. If the ping is not successful then you can try changing the port number to 2171. At last check if there is any certification or private key is attached for this installation. The first and second answer was correct for sure.

I am waiting for hearing from you.

Thank you,

Riley weaver.
