The error “failed with status code 1030” is a generic network error code indicating that the connection to your Citrix environment has failed.

There is a very simple fix for this error code. The steps are as followed:

1. Click on Start > Run
2. Browse to CMD to open the command prompt
3. Type ipconfig/flushdns > enter
4. Log on to Citrix again

When you flush the DNS you are removing any old DNS entries on the target and the Delivery Controller. Basically you are clearing the DNS Cache.

According to Citrix: The Cause of this problem is explained as “It was observed that the launch.ica file for the XenDesktop session appeared to contain a non-routable address, it was confirmed that the address belongs to a secondary NIC on XenDesktop virtual machine that is used for streaming the image using Citrix Provisioning Services. This happened because the secondary NIC with a private address on the provisioned target machine was registered with the DNS server.”
