Working on a Provisioning Server project, I had to deal with the Trend Officescan product installation.
The problem was really critical because installing the Antivirus Software within the image would lead to a blue screen at boot time.
Not installing the software was not an option, as the Security Administrator would have not allowed that because even if the servers are "Read Only" they could be virus propagation vector.
During investigations we've found that if the antivirus software was installed at each boot (so not incorporated within the image but installed on top of it) the blue screen issue was over and the Antivirus Software perfectly working.
To automate the deployment process we decided to write a script and push it by machine GPO.
To ease administration processes and ensure the Antivirus Installation would never happen within a private image, I've developped the script provided in this article.
Working on a Provisioning Server Project we've decided to use Device Hard Drive Cache.
However during the initial tests, we've faced an issue : How to automate the creation of the Cache Partition on the physical drives ?
To do so, we've developped a little script, launched at Computer Startup by GPO.
At first server boot on image, the local disk is not present, causing Provisioning Server to fallback on Server Side cache.
The following script will then initialize and format the cache partition which will be available for the PVS Client at next reboot.
Working on XenDesktop POCs and Deployments I've done some researches on how to optimize XenDesktop UPD printing just like in XenApp (check this article for more details).
With XenDesktop 2, it was possible to modify the DefaultPrnFlags value (which controls the Citrix printers autocreation process) using the following procedure.
With XenDesktop 3, things are a little bit different, as the Printing Subsystem is now closer to the XenApp One ...
I've recently faced an issue regarding using Provisioning Server (4.5, & 5.0) to provision XenApp VMs on XenServer hosts.
The VM's were booting properly and were responding correctly through XenCenter but was freezing when accessed through network (either ICA or RDP for example)
I had used all registry tips from KB (EnableOffload reg value turned to 0 ...) without any success getting my VM to work properly ...
This "Tech Tip" article is focused on a very useful Security Setting You might want to enable on your Terminal Servers Farms.
By default, Windows allows Users to store their Network and Messaging (Exchange, .Net Passport) Passwords.
The first problem is that these settings are not stored in the User Profile but locally on the Server in an encrypted base.
The Second problem is that you may want Users to be able to save such informations (When Defining Several Outlook Profiles for User convenience for example) ...
You may have encountered this issue while running a Terminal Server or Citrix XenApp Project.
The Symtoms are quite simple to illustrate : Users are facing (random) significant Logon Delays and the logon process is hanging on "Applying Registry Settings".
According to Microsoft, this can occur if most of the following conditions are met ...
When troubleshooting an EdgeSight 5.0 SP1 Issue on XenApp 4.5 HRP03, I got the Following workaround from Citrix (as originally this is a DotNet Framework Issue) to deal with the "Citrix End User Experiencing Monitoring Service" not starting correctly and Generating DCOM errors event ID 10005 and Event ID 7000 : "The service did not respond to the start or control request in a timely fashion"
To solve this issue ...
When troubleshooting an EdgeSight 5.0 SP1 Issue on XenApp 4.5 HRP03, I got the Following workaround from Citrix (as originally this is a DotNet Framework Issue) to deal with the "Citrix End User Experiencing Monitoring Service" not starting correctly :
Create a SemsService.exe.config file within the %ProgramFiles%\Citrix\EUEM\Service\ folder with the following content
You would say what's the matter with the Article Title "CitrixTools.Net Tools are Slow to Launch" ?
Actually I've been trying to find for weeks why in some cases All the Tools published on this Site were so Slow to Launch in some cases (Not Always).
And Guess What ? ...
The purpose of this Article is to summarize and illustrate the different ways an Administrator can use to take a XenApp Server Offline for Maintenance purposes.
A XenApp could need to be Isolated from production, either for Maintenance purposes (System or XenApp Updates, for example) or because the Server is unstable and should be removed from available servers.
To Isolate a Server, XenApp Admins can use different methods ...
This Article is based on another nice article written initially in French by Laurent Falguiere.
Windows 2008 Terminal Services introduce a new functionnality called "Drain Mode".
This new functionnality allows Admins to connect to a Terminal Server while Users can not (Only disconnected sessions will be able to reconnect, while new sessions won't be allowed).
Actually, when a server is configured in this mode ...
