When a user attempts to enumerate using the StoreWeb URL in a browser, not all icons are not enumerated. This can also occasionally result in enumeration failure and an error stating "Cannot complete your request" during enumeration.
On the Storefront server, Windows Event Viewer > Applications and Services Logs > Citrix Delivery Services shows an unhandled exception error Event ID 3005 for w3wp.exe with account name: IIS APPPOOL\Citrix Receiver for Web
WARNING: Please back up the web.config file to a safe location before editing any entries.
Find the following entry <appSettings> in the web.config file, and add the values as follows:
<appSettings>
<add key="aspnet:RequestQueueLimitPerSession" value="2147483647"/>
</appSettings>
After an IIS reset, attempt to login again and observe the event viewer logs ensure there is not another 3005 event.
This occurs because the default ASP buffer per session limit is being exceeded in IIS.
