Application could not be published in folder: No object found - Citrix XenApp

Error:
Citrix XenApp 6.5

Application could not be published in folder:

No object found

The above error pops up on many reasons and couple of them are here:

1. Check folder permissons
User doesn't have permissions to publish in that folder which causes the error. Providing required permissions to the user will fix the issue.

2. XenApp server - MFcom service error
If MFcom service in "starting" mode:
Stop IMA service (Net stop IMASERVICE)
Recreate the LHC (dsmaint recreateLHC)
Start IMA service (Net start IMASERVICE)
Start MFCOM service

Even, the service fails/hangs, run the repair on xenapp from control panel programs

3. Database had a stale record of XenApp/Data Collector server

In my case, the error occurred because the DB had a stale record of data collector server where I was running Citrix App Center.

Steps to fix it:
1. Take backup of the Database
2. run dscheck commands to clean it. (dscheck /clean)
3. Remove XenApp/DC server from the farm using Xenapp Role Manager. The uninstalling of the Xenapp is not recommended here ( I tried uninstall of Xenapp and it didn't fix my issue).
4. Clean up the Database again using dscheck /clean command
5. Rejoin the Xenapp/DC server to the farm using XenApp Role Manager

Now I am able to successfully publish apps in the farm.

4. Check that your/problemtic user id's member groups. Some cases the user id may be members of both read only admins and full admins groups. You need to remove either group from appcenter console or user id from read only admins group.

Have a nice day!

Error: java.lang.nullpointerexception

I have got the error "java.lang.nullpointerexception" when I tried to install Oracle 11g client. It was caused due to unavilability of  folder to write install logs in admin mode.

In my case, it was looking for my home directory to write log files.

Solution:

Run cmd prompt in admin mode
map home directory with teh follwoing command
net use x: \\servername\share\home_folder

Then,
Run Oracle client setup in admin mode.

Have a nice day!

Remote logins disabled after server reboot

This was caused by many reasons. One of the reason was  that when the elected zone data collector server was rebooted, servers that rebooted at that time, couldn't contact the zone master and had logins disabled.
Some one disbale logins manually through Citrix console.

It happens when LHC corrupted.

Solution:

Follow one of these solutions based on your findings

1. Make a preferred zone master and make it its reboot schedule in other time than remaining servers.

2. Enable logins through Citrix console

3. Recreate LHC

4. Create a schedule task with
SCHTASKS /create /tn "OpenCitrixLogon" /TR "cmd /c change logon /enable" /SC daily /RU "NT Authority\System" /ST 06:00 /F

5. Change Registry key through a batch file after reboot. You can also run it through a scheduled task.

HKLM\System\CurrentControlSet\Control\Terminal Server

DWORD = fDenyTSConnections
Value = 0

Citrix Analysis & Audit Tools

There are few tools in google world. Recently I came across these two:

Citrix Scout:

http://support.citrix.com/article/CTX130147

Download it from above link. Unzip it and copy it to Data Collector server.

Run it on Data Collector server.

XenApp Audit Tool:

Install Citrix SDK (Power shell) on Data collector server if it is not installed already. The download path for Xenapp6.5 SDK is

http://community.citrix.com/display/xa/XenApp+6.5+Powershell+SDK

Download XenApp Audit tool from

http://paultechnologies.com/xenappaudit/

Unzip XenAppAudit in “Program Files” folder

Run start.bat as administrator

The results will be saved in “Results” folder.

Soem times, you will get errors if your XenApp installation directory is different. In that case modify the Launcher.vbs  to the correct location of the wfshell.exe. Wfshesll.exe is needed to find out the version of XenApp.   In the Launcher.vbs file, you can also modify the path as necessary for the SDK if the SDK installation path is different.

XenApp Server not accepting connections/Unable to launch your application

Error:

Unable to launch your application. Contact your help desk with the following information: Cannot connect to the Citrix XenApp server. The Citrix XenApp server you have selected is not accepting connections.

There are many reasons:

1. Load Evaluator

Check parameters of load evaluators. Check load on server using command Qfarm /load.

2. DNS/host entries on client side

Check DNS/"Host file" on client systems and verify that you are resolving server names successfully on client workstations.

My situation the client is using host name for name resolution. His host file had wrong entries.

3. Check that the application has been published on right server

4. Verify with firewall team that right ports are opened or not. Do telnet from client work station on 1494 or 2598, 80,443 ports

Ex: telnet serverName 1494
      telnet SerevrIP 1494

if it is successful, you should see ICA

Citrix Printing was not working Xenapp6.5/Printer Auto creation fails with status 0x5

Recently I came across a printing issue farmwide...
Client printers were not mapping. I have enabled client printer mapping policies and Citrix Univesal print driver policies but still client printers were not mapping..

I have solved the issues with the following fixes:

1. Windows printer was selected and grayed out in ICA-TCP properties
Solution: To enable Windows printer I have disabled the "Do not allow Client print redirection" in AD GPO under computer configuration --->Administrative templates-->WIndows components---> Remote Desktop Services-->Remote desktop session host-->Printer redirection

2. Citrix polices the Univer printer driver was not set correct
Solution: I have selected the "use Citrix universal printer if the requested driver is not availble" under user unfiltered policy ---> prnting--> Driver --> Universal print driver usage.

3. Print spooler Service was disabled
Soluton: I have enabled print spooler service and restarted it.

4. Missing Citrix Universal print driver in print server properties
Solution: Installed the Citrix UPD from CD

5. Printer auto creation fails with the status 0x5
Solution: Citrix printing sevice was starting with local account. I have changed the sevice to log on with Local SYSTEM account.

After following the above steps, now I am able to get client printers in Citrix sessions.

Suppressing Server name pop ups for Receiver installs

There are so many ways:

1. You can supress the server name pop ups for new Receiver client installation by renaming CitrixReceiver.exe as CitrixReceiverWeb.exe. The name is case sensitive. If you install receiver client using "CitrixReceiverWeb.exe", then it doesn't show pop ups for server name.

2. Add "/ALLOWADDSTORE=N" switch while instaling through commandline

3. Changing Registry values post installation to suppress the Add Account window.

Under HKLM\Software\Citrix\Dazzle, set AllowAddStore value to N. Restart Citrix Receiver for Windows to apply the new Registry value.

4. Adding the follwoing reg keys under Hkey_Current_User

Citrix Web Interface - Delay on first page

Whenever you restart IIS on WI or WI server, the first page takes one minute to get the Welcome page for first user. All other connections are normal until you restart IIS again.

Work Around:

This issue is caused by a CRL check sent to Verisign. If the Web Interface server cannot access the internet, the CRL check fails and times out.

Check in IIS for the ASP.net version that is in use with the Web Interface site.
Modify Aspnet.config  in the following directory
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 (If Web Interface uses .Net framework v2.0.50727)



Add the following lines to your ASPNET.CONFIG or APP.CONFIG         

      <*?xml version="1.0" encoding="utf-8"?*>
  <*configuration*>
   <*runtime*>
      <*generatePublisherEvidence enabled="false"/*>
     <*/runtime*>
 <*/configuration*>

Note:  Remove * stars before and after in each line.
The ASPNET.CONFIG file location would be:
c:\Windows\Microsoft.NET\Framework64\v2.0.50727
For a 32-bit application it would be:
c:\Windows\Microsoft.NET\Framework\v2.0.50727
