Download the .tgz upgrade file from here https://www.citrix.co.uk/downloads/netscaler-adc/firmware.html

Save your configuration first ( remember this does not save automatically ) and backup a config backup.

If this is a virtual machine do a snapshot / chekpoint

Let’s get started with the upgrade wizard:

NetScaler upgrade wizard

select the location for the firmware file:

Firmware

Next, verify the licenses you have already installed these will work with the new netscaler and begin the upgrade.\

NetScaler upgrade warning

The upgrade will take down the gui first , then after the netscaler when it says rebooting

Other key things to note – the upgrade has turned back on SSLv3 support on the Gateway vServer…however, it has enabled support for TLSv1.1 and TLSv1.2 which was missing from the 8007.e release. Nice!

SSL TLS

 

 

The new web interface will look like below

If you see a solid black screen after upgrade you will need to delete your cache or do a CTRL and F5

 

Note

Double check the SSL Profile on your virtual server make sure it’s set to : ns_default_ssl_profile_frontend

With SSL3 off and TLS 1.2 on , you can check via : https://www.ssllabs.com/ssltest/

Resolution 1:

Active folder would be missing. Copy the Active folder ”C:\Program Files\Citrix\SMA\Active” from another server and then start the service.

Resolution 2:

To resolve the preceding issue, complete the following procedure:

•Stop the SmaService.exe service by using the Task Manager.
•Citrix SMA Service Properties and under the Log on tab, select Local System Account.
•Set the SMA  Service to Manual and restart it, once the service started.
•Change Citrix SMA Service Properties and under the Log on tab, select Local Service Account.
•Set the SMA  Service to Automatic and restart it.

Resolution 3.

Stop IMA service (Kill both IMASRV and IMAAdvanceSRV) and SMA services (SmaService).
Run “dsmaint recreatelhc”
Start IMA service and then SMA service.

Recently had a Citrix server start to pulse on Disk Space useage in Monitoring where it would use 25 Gig’s in an hour then clear which brought up waves on the disk usage monitoring. The good news was that it was happening every hour so easily trackable in realtime.

I used performance monitor to check what the top process was that was writing to disk which was System … which did not help

Then I checked the folder, that System process was writing to the most, which picked up to be this single file : 

C:\Windows\System32\LogFiles\UserProfileManager\%domain.local%#%servername%_pm_config

Checking this file and it was 20 Gigabytes which would be the largest Config File I have ever seen!

I restart the Citrix Profile Management Service which dropped the File back down to 378kb and stopped the excessive disk writes/useage!

Check error logs on StoreFront servers and netscaler

Check if theres any Schannel errors in Log of StoreFront ( Datacollector Servers ) and reboot if so

Check the STA settings on the Netscaler

  1. Configuration tab, in the navigation pane, expand NetScaler Gatewayand then click Virtual Servers.
  2. In the details pane, select a virtual server and then click Open.
  3. On the Published Applications tab, under Secure Ticket Authority, click Add.
  4. In the Configure STA Server dialog box, enter the URL of the STA server and then click Create.
    1. This will be http://datacollector or ip
  5. Repeat Step 4 to add additional STA servers and then click OK in the Configure NetScaler Gateway Virtual Server dialog box.

citrixiconRecently I went through this to update a Cert on a Gatewat: http://fixmyitsystem.com/2012/07/configure-citrix-xenapp-web-site-to-use.html

However the SSL certificate was still not updated

If you route traffic over a different port you need to run through this as well : 

Start , All Programs , Citrix , Administraion Tools , Secure Gateway Configuration Wizard

Choose Next and Standard

Pick your new Cert

Leave the rest of the options as default

Seems to be on Citrix 4.2 reciever as well :

  • On an affected client PC, run REGEDIT
  • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\WFClient (64-bit PC assumed) – HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\WFClient ( 32bit )
  • Create a new REG_SZ value and name it CbChainInterval
  • Open the newly created value and enter the value as 1000

The values accepted are from 0 to 2000 inclusive and is in milliseconds. I would suggest starting with a value of 500. If this doesn’t work then try with a lower value 400 and so on until resolution.

You need to note that detection of changes will take at least double the value addressed above.

and_receiver_h24bit_512If you would like to access your local applications from inside a Citrix XenApp server you will need to do the following :

Install the Citrix Reciever with these parameters : CitrixReceiverEnterprise.exe ALLOW_CLIENTHOSTEDAPPSSHORTCUTS=1 ALLOW_URLREDIRECTION=1

Set the following registry Value
HKCU\Software\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Control\ClientHostedAppsShortcuts = TRUE

Modify the ICA file to the server to add the following line under the server heading e.g.

[melxatest344F]
ClientHostedAppsShortcuts=1
Address=x.x.x.x:1494
AudioBandwidthLimit=0
AutologonAllowed=ON
BrowserProtocol=HTTPonTCP
CGPAddress=*:2598
ClientAudio=On
ConnectionBar=1
DesiredColor=8

Once enabled you will have a Local Program Folder appear in your Citrix Xen App Session

Repeater8540_FrontWtop_HR_512Upgrading a Citrix branch repeater ( Now called CloudBridge)  to the latest firmware requires the License currently installed to be in date and under maintenance. If you renew your Citrix Maintenance you need to re-download all your licenses and reupload them to the branch repeater before it accepts the new firmware file.

Upon reuploading one of the new License file to a branch repeater I was given the error

Add License failed: The license is not an upgrade license which is required since a base license is already installed

This required me to delete the current license from the Citrix Branch Repeater ( Warning this will disconnect accelerated connections so make sure you do this out of production hours ) and reupload the license.

worksiteWhen selecting multiple files in iManage worksite and right clicking and choosing open , it crashes Word on opening

To resolve this, the following registry key will need adding >:

Citrix server: HKEY_Current_User\Software\Microsoft\Office\14.0\Word\Options “DisableRobustifiedUNC”=Dword:00000001
