Last week I have installed a Microsoft UAG array. I installed Microsoft ForeFront Unified Access Gateway 2010 including Service Pack 1. When using an array configuration you have to deploy Microsoft’s Network Load Balancing (NLB) for redundancy and load balancing purposes. I configured NLB with multicast and IGMP support. I had configured some HTTPS trunks and some HTTP trunks for http-to-https redirection.
Everything was working perfectly and I decided to install the update KB2585140 (ForeFront UAG SP1 Update 1). The main reason for installation was the introduction of SharePoint 2010 with Office Web Apps and Lync web services publishing.
The installation process was easy and completed without any errors. I noticed that after installing the update I couldn’t activate any configuration changes. Everything I hit Activate I receive the following error message:
The Activation works again by deleting all HTTP trunks and only use HTTPS trunks. The customer started a support call with Microsoft and Microsoft acknowledges this behavior when installing the update on an array configuration. At first Microsoft advised to “break” the array and use a stand-alone server deployment. If that isn’t an option we should uninstall the update. We are told that the current configuration will get to the configuration state prior to the installation.
This morning the customer received another e-mail from Microsoft stating at more and more calls were logged with the same issues. The issues now has the highest priority for the Microsoft UAG developers. Microsoft couldn’t tell when the issue will be fixed, but I guess very soon.
So when using a Microsoft UAG array configuration DON’T install Microsoft UAG SP1 Update-1.
