How to Prepopulate Citrix Receiver 3.x with Services Site URL through registry

Citrix has released an article that describes what registry key to edit in order to prepopulate a Services site URL in Citrix Receiver 3.x.

Procedure

Caution! This procedure requires you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Back up the registry before you edit it.

Complete the following steps to edit the registry key:

  • Open registry and navigate to
  • For 64-bit machines: HKEY_LOCAL_MACHINESOFTWAREWow6432NodeCitrixPNAgent
  • For 32-bit machines: HKEY_LOCAL_MACHINESOFTWARE Citrix
  • Restart the machine for changes to take effect. Now, the receiver is prepopulated with the information placed into the ServerURL string.

XenDesktop 5.x VDA Registry Based Registration – Best Practices

Registry based VDA Registration

List more than one controller on ListOfDDCs registry key separated by a space to prevent registration issues if a controller is not available.

• Example DDC5.xd.local DDC6.xd.local

o HKEY_LOCAL_MACHINE SoftwareCitrixVirtualDesktopAgentListOfDDCs

o 64Bit – HKEY_LOCAL_MACHINESoftware Wow6432CitrixVirtualDesktopAgentListOfDDCs (REG_SZ)

Ensure all values listed under ListOfDDCs map to a valid fully qualified domain name to prevent startup registration delays.

XenDesktop 5.5 and higher supports registration groups by adding parenthesis around each group. This feature addition allows you to create groups of brokers to load balance Virtual Desktop Agent registrations. Once you have defined groups of brokers, registrations attempts are made against Broker 1 in Group 1, then against Broker 2 in Group 1, and so on. If all registration attempts against Group 1 brokers fail, attempts are made against Group 2 brokers, and so on.

• Example (DDC1.local.domain DDC2.local.domain) (DDC3.local.domain DDC4.local.domain)

Note:The VDA (Citrix Desktop Service) will randomly select DDCs from the list (grouped or ungrouped) until a successful connection to a DDC is established.

Disable welcome screen IE8/IE9

I don’t know about you, but I am so annoyed with this screen, mostly because it always pops out when I least expect it, for example, when I’m in the middle of a demo or a class, and even when I think it won’t appear, because that nasty designer has probably deliberately configured it in such a way that there’s a slight delay between the opening of the IE window, and the pop up welcome screen. Even more nagging, running through the welcome screen will then pop up a new IE tab, taking you to a web page that you do not want to be at, causing you to again waste even more time. Needless to say, in the days Continue reading “Disable welcome screen IE8/IE9”

Install a .REG file without using REGEDIT.EXE

This is pure VBScript code, that also works when access to REGEDIT is denied by policy. Can be easily called from loginscripts. Not feature-complete (only strings and DWORDs) but works with most .REG files. Continue reading “Install a .REG file without using REGEDIT.EXE”
