Citrix XenServer note

1. windows 7/server 2008 cannot added in Windows server active directory Domain.

::

set DNS server IP to active directory controller's IP.

 

2. when I run desktop studio it comes up with ''the current users does not appears to be a memebe of active directory domain. desktop studio cant be run by a local user account. reload the snap-in to retry''. The server is a member of domain and am using admin account to logon to the server, inshort I used one password for all the 4 servers in the domain.  Just dont what the problem is with the account am using to run the desktop studio.

::

login using (domainname\domainadministrator).

::

did you make copy of would be domain controller to configure Xen Desktop controller , if yes please run sysprep on the server you are planning configure as desktop controller or on the server on which you are trying to install the desktop studio, after running sysprep add it to the domain again and then start installation of desktop studio.

When i am having the problem i noticed another thing, that is my UAC is enabled. Actually while my computer is in good conditon i disabled it. So this time i tryed to disable UAC in command line with the command below:

reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f

Then i restart my computer, then the system goes right again.

　　1.关闭UAC功能的方法是，在“控制面板”→“用户帐户”中，点击“打开或关闭用户帐户控制”一项进行设置。而如果想微调UAC功能，则可按选键盘上Windows键+R键，调出“运行”对话框，然后键入“secpol.msc”，打开“本地安全策略”设置窗口。

　　2.在“本地安全设置”窗口中，在窗口左边依次点击“本地策略” →“安全选项”，窗口右边会对应显示出多个“用户帐户控制”功能的具体设置项目。有经验的电脑用户可以根据自己的喜好，对其中的项目作出修改，以符合自己使用电脑的习惯。

　　3.例如，有些人会将“管理员批准模式中系统管理员的提升行为”由“同意提示”改为“不提示直接提升”;同时将“只提升签名并验证的可执行文件”一项由“已禁用”改为“已启用”。虽然修改设置会削弱UAC本身的效力，但用户在进行管理操作时却能减少警告窗口弹出的次数。

　　4.使用Norton UAC Tool。它可以把UAC设置为始终允许某一程序。安装后UAC的提示窗口会有一个复选框“始终允许该程序”，这样可以把的升级程序等设为始终放行，方便操作。

　　5.暂时关闭UAC。先打开，结束explorer.exe，就没了，然后按下“显示所有用户的进程”，会出来一个UAC窗口，放行。然后打开“文件->新任务”，会看到“将以管理员身份运行此程序”，输入explorer.exe回车，重开桌面，就暂时禁止了UAC。原理：按下“显示所有用户的进程”并放行后，任务管理器被提升权限，在UAC中权限可以继承，开启explorer.exe后，桌面继承权限，在桌面上运行的程序也自然继承了权限。要开启UAC，结束explorer.exe再重开，就恢复了。

 

3. Sometimes when installing XenDesktop 5, we can find the connection error to our SQLExpress "The current credentials to Have Insufficient privileges and access the database server Perform the NECESSARY operations". 
::
This error is a typical mistake of making a clone of a VM in a virtual environment, this is because the VM is running DDC has the same identifier as an existing domain in which we are working to solve this problem Therefore we run our server and restart sysprep.exe and subsequently to install XenDesktop 5 again.
The instruction to do is:
sysprep.exe /generalize /oobe /shutdown

Sysprep on Windows 2008 R2, can be found in C:\Windows\System32\sysprep

 

4. vms unregister on XenDesktop server

::

reconfigure VDA(reset XenDesktop controller's location) or reinstall virtualdesktopagent

 

 

5. Citrix Receiver hang on "sending module options to server"

::

set env var LANG="C" in Client.

I'm not sure about VHD's from acronis, but I have done the following with Vitrual Server VHD's successfully:

1. Copy VHD to NFS or EXT3 storage
2. Rename to UUID.vhd (pick a unique UUID, I usually just index up by 1 off of an existing one)
3. Run xe sr-scan uuid=sr-uuid (you can use xe sr-list name-label=sr-name
4. Set a Name Label using xe vdi-param-set uuid=disk-uuid name-label=disk-name
5. Attach the imported disk to a VM
