XenApp 7.5 XenDesktop 7.5 Announcement
Citrix have recently announced XenApp 7.5 which is built upon Flexcast Management Architecture (FMA) and has been available within XenDesktop 7.0, 7.1 within the App Edition license tier. The least releases also brings with it XA hybrid cloud provisioning meaning that SysAdmins now are able to extend there private cloud to IaaS hosted cloud providers (ISP’s) provided they leverage Citrix CloudPlatform which will enable quick scalability and elasticity and without having to learn the ISP’s chosen design, build, provision and management consoles to provision your environment as it’s all integrated into Studio.

Multi-Site Configurations & High Availability
Coming soon! I will cover multiple data centres and sites and how-to enable and ensure H/A access to your published resources if you lost/lose communication with your XenDesktop 7 delivery controller(s) and the pitfalls. I would strongly recommend your environment is N+1 and with VM’s common these days setting and configuring an N+1 environment should be best practise for H/A, business continuity and DR.

How-to Enable Local App Access

Howto Configure Email Based Discovery& Why It’s Important
Configuration of email based discovery using SRV records is simple and greatly enhances the users login experiences as they all know there email addr and domain password much like logging into Facebook, Twitter e.t.c so offering the same login user experience weather users are in or outside or the organisation means they don’t need to remember logging in with the following format domain\username and domain password they can simple use there corporate email addr and domain password.

There is a great Citrix blog article that covers covers configuration of e-mail based discovery in and outside of your organisation leveraging a NetScaler Gateway check out – http://blogs.citrix.com/2013/04/01/configuring-email-based-account-discovery-for-citrix-receiver/.

The process below is for configuration of SRV records within a trusted corporate environment. If you would like to know more about what else you can configure in terms of SRV records check out – http://en.wikipedia.org/wiki/SRV_record, http://technet.microsoft.com/en-us/library/cc961719.aspx (A Windows 2000 article but will get you thinking if your new to SRV records) and howto add other resources records into your organisations DNS – http://technet.microsoft.com/en-us/library/cc772362.aspx.

1: Launch your Microsoft DNS management console
2: Right click on your organisations Forward Lookup Zone that contains the StoreFront FQDN
3: Click “Other New Records”
4: Scroll down and select “Service Locaiton (SRV)” and click “Create Record”
5: Your organisations domain should already be pre-populated e.g citrix.lab or axendatacentre.com
6: Type in “_citrixreceiver” in the Service feild
7: Type in “_tcp” in the Protocol field
8: Type in “443” in the Port number field or 80 if you don’t use 443 internally
9: Type in “storefront.domain” in the Hosting offering this service e.g storefront.axendatacentre.com or storefront.axendc.local
10: Save/Commit the changes and close the current active window in DNS
11: Navigate to physical or virtual machine install and launch Citrix Receiver when prompted enter in your email addr and password when prompted.

Troubleshooting
Open up a Windows Command prompt and execute these two commands below and for more information in validating your SRV records check out – http://support.microsoft.com/kb/816587.

1: Type in “ipconfig /flushdns”
2: Type in “nslookup”
3: Type in “set type=srv”
4: Type in “_citrixreceiver._tcp.domain” e.g _citrixreceiver._tcp.axendatacentre.com
