Starting from XenApp/XenDesktop 7.x we have maintenance mode option on the Citrix app servers directly. We can turn on or off the maintenance mode on the servers which will only disable Citrix sessions on those servers. RDP connection will still work on the faulty app server. In XenApp 6.5 appcenter, we can only disable logons to the servers which will also disable RDP access to the server. Using load evaluator, we can come around this issue and disable only Citrix logins, while making sure that RDP still works.

Have you configured raspberry pi in your environment? If yes, have you ever felt that it is very slow or not responding at all? I’ve had the same problem and I’ve fixed it. Read more to find the solutions that I’ve used to fix it.
I have been using raspberry pi from last 3 years with sandisk 32 GB SD card. If you’re using raspberrypi you already know by now, they don’t sell charging socket separately.
Issue: We had to reboot our ADC. We were not able to save the configuration both from GUI and command line in ADC. We did a force reboot. When powering on, we observed lot of license related errors like “The license info cannot be fetched” " No licenses were found" etc.. But after logging in, we were able to see the license file. After netscaler is powered on, we were not able to login through GUI and ssh.
If you’d like to secure xml traffic from storefront to DDC, you should install certificates on the DDC. If you have IIS installed in your DDC server, then mapping the certificate to 443 is very straight forward process. Open IIS manager (inetmgr), select your server and then select server certificates. Import the certificate along with private key and bind it to 443. If you do not have IIS installed in your DDC server, then you should install the certificate on the DDC server and run netsh commands to link that certificate to citrix DDC software.
After you upgrade your citrix site, or on a new citrix site creation, when you open director portal, under sessions/logon performance tab for logon duration details it shows “no data is available for the specified time period”.
Based on your CVAD version, copy the source files into a folder on your VDA (app servers). Goto iso\x64\Virtual Desktop components folder and right click on UpmVDAPlugin_x64.msi file and click repair. complete repair and reboot the server.
On a new install of VDA software from CVAD 1912 LTSR CU5 version and higher, when you run the VDA software from AutoSelect.exe file and enter all the details, after it prompts for reboot, installation will not continue.
Even if you nagivate to your software path and retry to launch the setup, GUI will not show up.
This is because in the registry path, HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce there was a key created with the name “!
Issue:
After upgrade, when you open the netscaler gateway url, instead of showing the username and password page, it immediately shows a white page.
Solution:
This is mostly seen when upgrading from 10.5 to 11. From a working netscaler copy the folder, /netscaler/ns_gui/vpn and replace this folder on your current netscaler. Refresh the gateway vip url. It should work. You can also check the gateway url. If it is /vpn/index.html, check the index.
Issue:
After upgrading netscalers to 13.0 84 version from 12.1, on RfwebUI theme for Citrix gateway VIP URL, the URL opens as expected but when users login, it immediately throws an error on screen “Cannot complete your request”
On default theme (black theme), after users enters their credentials and click signin, it says Http/1.1 Internal Server Error 43531
Solution1:
While using classic policies on 12.1 ADC version, session policy is configured as REQ.
Space issue on /flash partition Netscaler ADC 12.1 does not save the configuration. When clicked on the save icon in the browser, it prompts whether you want to save running configuration. Nothing happens when you click yes. From the putty session, when you run “save config” command, it outputs “ERROR:” and no error message is displayed on the putty console.
Solution:
Login to your netscaler through putty and check the free space of /flash directory.
