Error: “The Network Connection to your Application was Interrupted” on ICA Client

RD Licensing formerly Terminal Services Licensing (TS Licensing), manages the Remote Desktop Services client access licenses (RDS CALs) that are required for each device or user to connect to a Remote Desktop Session Host (RD Session Host) server

Broker Database would have a new table for maintaining RDS CAL as a key/value pair. On a non-Windows client connection to a TS VDA, if a license is checked out, ICA populates the registry entries. Behaviour on following session events is described below:

  • On Logon or Reconnect:

HKLMSoftwareCitrixMSLicensigReplicateCache registry key and corresponding nodes under HKLMSoftwareCitrixMSLicensig registry key to check if any of the licenses has same index as RdsCalId.

  • On session audit event:

HKLMSoftwareCitrixMSLicensigReplicateCache registry key and corresponding nodes under HKLMSoftwareCitrixMSLicensing registry key. For each node under HKLMSoftwareCitrixMSLicensigReplicateCache registry key, Stack Control would read license information from corresponding node under HKLMSoftwareCitrixMSLicensing, create a blob of byte array and write license information to the blob.

  • On Validate event:

Create node and write license information to node under HKLMSoftwareCitrixMSLicensing
