| SnapIn config data store error |
 |
| Fiddler Trace |
As it turned out, there's one "other pre-requisite" if installing the Web Management Console on a Windows 8 environment: Windows Communication Foundation (WCF) HTTP Activation. Simply put, HTTP activation allows a WCF service to relay its messaging asynchronously over HTTP - in this case HTTPS. In Windows 8, HTTP Activation is turned off by default, unlike Windows Server.
The SnapIn config data store is a table in the GPWEBMANAGEMENT database (dbo.SnapInStorage) and stores the URL to the Session Central Service WCF service. I ran a SQL Profile trace and noticed that the Web Management Console was not able to reach the GPWEBMANAGEMENT database on the SQL Server to read the Session Central Service URL. Therefore, the Console was not able to communicate to the Session Central Service to obtain user session or tenant information.
To turn on HTTP Activation on Windows 8:
1. Open Control Panel
2. Select Programs
3. Click on Turn Windows features on or off
4. Expand .NET Framework 4.5 Advanced Services
5. Expand WCF Services
6. Click on the HTTP Activation checkmark

Once the services were up and running, the Web Management Console worked like a charm.
Many thanks to Daryl Anderson and Grant Swenson at Microsoft for assisting with this one.
Until next post!

Are there any other recommended solutions?

Thanks!
Check the values in your SnapIn and SnapInStorage tables in the GPCONFIGURATION database. Make sure you have matching entries. For example, this is what I see in my SnapIn table:
Id Name Description
C7851276-926E-499C-9811-11A6A283A318 Dexterity Service Management The Web Management Console DexNext Snapin, used for managing gp service instances on multiple servers.
AC144217-80A3-49AF-8BB0-B6AA7C942D20 Session Management The Web Management Console Session Snapin, used for managing session instances on multiple session servers.
0721689D-1ADC-4B74-961B-E254E7373D57 Home
And this is what I see in my SnapInStorage table:
Id DataKey DataValue IsShareable
AC144217-80A3-49AF-8BB0-B6AA7C942D20 SessionCentralUrl https://MGB003:48650/SessionCentralService 1
As you can tell, the Id value for the Web Management Console must match that of the SnapInStorage and the SnapInStorage must contain a valid address to the SessionCentralService URI
I have this issue and added the HTTP but it did not work. I only have the 1 file in the Snapin table, AC144217-80A3-49AF-8BB0-B6AA7C942D20 Session Management The Web Management Console Session Snapin. I do not have the DexNext Snapin.
What have I missed?

This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. If your service is being hosted in IIS you can fix the problem by setting 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true or specifying 'system.serviceModel/serviceHostingEnvironment/baseAddressPrefixFilters'.
Immediately I remembered that I had set up the web client's website with 2 bindings, one configured by IP and the other configured by FQN. I opened IIS Manager and delete the IP binding. Then I rebooted the website, the Session Central service and GP Session Services and voilà! it worked like a charm.
