[Quick Post] Citrix Receiver – Clean uninstall tool – #vDM30in30

The issue

On my work based Windows 8.1 VM, I was finding that Citrix Receiver would crash any time I opened an ICA file from a Web Interface/StoreFront website, this meant that any desktop or application would not work.

  • I removed Citrix Receiver
  • I upgraded Citrix Receiver
  • I installed as the actual local admin
  • I installed the plugins for other browsers

But every time, the same, the process would stop responding.

The Fix

Occasionally software vendors release “clean up” tools, to remove their pesky applications completely, to fix underlying issues. And Citrix are the same.

So I ran this, rebooted my machine. Installed the latest Citrix Receiver, connected up to my customers environment, and voila, it worked!

So this is a quick post incase anyone didn’t know this tool existed.

Citrix XenDesktop – Password Reset not working on Wyse Terminals

The Issue

Users password has expired

When logging onto a Wyse Client (in this case a C10LE or Dx0D running the latest firmware), you are told your password has expired. You are given the option to change your password, once you click OK, you are presented with the following message;

2015-09-21_11-26-17

The Cause

Turning on Verbose mode on the Storefront server and running Microsoft DebugView Tool to view the output files (C:\Program Files\Citrix\Receiver Storefront\Admin\Trace)

Here is the Citrix KB on setting up verbose logging and reading the trace files.

Add-PSSnapin Citrix.DeliveryServices.Framework.Commands

Set-DSTraceLevel –All –TraceLevel Verbose

Get-Service "CitrixConfigurationReplication" | Restart-Service
Get-Service "CitrixCredentialWallet" | Restart-Service
Get-Service "CitrixDefaultDomainService" | Restart-Service
Get-Service "CitrixSubscriptionsStore" | Restart-Service
Get-Service "Citrix Peer Resolution Service" | Restart-Service

Set-DSTraceLevel –All –TraceLevel Off
  • In the debug we could see that when the password reset tokens were sent;
[21620] <?xml version="1.0" encoding="UTF-8"?><!DOCTYPE AdminProtocol SYSTEM "Admin.dtd">test.user</UserName><Domain type="NT">STUDENT</Domain><OldPassword>oranges</OldPassword><NewPassword>apples</NewPassword></RequestChangePassword></AdminProtocol>

Here you can make out that the above highlighted words are the user credentials and the old and new password.

  • There was a response stating;
[21620] PnaAuthenticationLogic: Authenticate response status: FailedInvalidDomain, isSuccess: False, password expired: False
  • We also seen a “Charlotte” error as well;
[21620] PnaAuthenticationExplicitController: PnaAuthenticationException from change password Citrix.DeliveryServices.PnaProtocol.Authentication.PnaAuthenticationException: CharlotteErrorBadCredentials

Below is a dissection of the debug output;

The Fix

The fix was to change the Wyse configuration file (WNOS.ini) for the line that puts in the available domains to the FQDN rather than the NETBIOS name for each domain.

Our old configuration was;

  • DomainList=”Student,Admin”

Our new configuration was;

  • DomainList=”Student.educationalcentre.co.uk,Admin.educationalcentre.co.uk”

We could then see that in the debug file, the line describing the domain details, includes the FQDN.

<Domain type="NT">STUDENT.Educationalcentre.co.uk</Domain>

This issue was not apparent when using Citrix XenDesktop 5.5 and Citrix Web Interface, only when we migrated to XenDesktop 7.6 and StoreFront Services, which I imagine uses a higher level of security, meaning passing the NETBIOS name through is unacceptable now.

Citrix StoreFront – Creating a Public SSL Certificate

The latest versions of Citrix receiver require that you use HTTPS for the server bound connections, otherwise you cannot connect.

Citrix reciever https error

And the information on the Citrix website can be a bit thin when it comes to using a Public CA SSL Certificate. Here is the documentation link to using certificates for the Storefront component.

Here I am covering;

  • Workaround – Bypassing the HTTPS SSL warning when adding a store to Citrix Receiver
  • Creating the Public SSL Certificate request for your StoreFront Server
  • Importing the Public SSL Certificate onto your StoreFront Server
  • Exporting the SSL Certificate for use on additional servers
  • Linking the SSL Certificate in IIS to the StoreFront Website
