Citrix StoreFront Credential Wallet service fails to start

If your StoreFront Server is not (!) connected to the Internet the service “Citrix Credential Wallet service” may fail to start with the following error:

The Citrix Credential Wallet service failed to start due to the following error:
The service did not respond to the start or control request in a timely fashion.
Evemt ID: 7000
Source: Service Control Manager

To fix this you have to change a setting in the following file:
C:\Program Files\Citrix\Receiver Storefront\Services\CredentialWallet\ Citrix.DeliveryServices.CredentialWallet.ServiceHost.exe.config

Open this file (e.g. with Notepad) and search for the following entry:
<runtime>
<!– Set enabled=false, if this machine does not have external access to the internet –>
<generatePublisherEvidence enabled="true"/>
</runtime>

Change the setting “generatePublisherEvidence enabled=”true”” into “generatePublisherEvidence enabled=”false”” and save the file. After changing this setting you should be able to start the “Citrix Credential Wallet service” even if your StoreFront-Server is not connected to the Internet.
