While adding VMs created by Citrix Provisioning Services, you may receive this error : Error : ‘Error expanding node’ . This issue occurred as the machine catalogue was initially created in PVS version 6.x. and current PVS version is higher than that. This is a well-known issue and a Citrix article is available here .

I was working with my colleague when he pointed out to me an intersting icon in PVS console - a desktop with a grey wrench on it. When I tried to change the target device from Production to Maintenance / Test, I could not because it grayed out. Upon checking for a few minutes, it turned out that the specific target device was set as template device for the said collection. How to check on that? At PVS console, on the left side, click at Collection. We will see our device collections on the right side.

Oh wait, just before you planned to kill someone, you realized there were red dots / circles at the configurations, and those configurations (with red dots / circles ) were the one who drove you crazy! Configurations with green straight lines / circles

A few weeks ago I went to AppSense training. It was very good, very informative and very intense - 5 days were not enough to be honest as it covers all 4 components of DesktopNow (AppSense Management Console, Performance Manager, Environment Manager, and Application Manager). So back to the topic - I received this error while trying to pool the policy : Failed to poll Now : Not enough server storage is available to process this command. A bit digging, I managed to find why it happened, and how to resolve it. According to Microsoft : "This issue may occur if the IRPStackSize registry entry on the server is set too low." Now, what is IRPStackSize ?  According to Microsoft :  The IRPStackSize parameter specifies the number of stack locations in I/O request packets (IRPs) that are used by Windows 2000 Server, by Windows Server 2003, and by Windows XP. You may have to increase this number for certain transports, for media access control (MAC) drivers, or for fi

A bit different thing today, a simple task but greatly helps me in getting my jobs done fast. I am in the middle of housekeeping our Citrix licenses as it needs to be renewed. Due to the fact that we are using User/Device model, some users who are already left the Company might have their ID still utilizing the licenses. By freeing up the licenses, it will help the Company to reduce Operational costs and assign the licenses to the other users. Well, it is almost year end, and everybody is coming up with their plan for performance review, why shouldn't I? ^__^! Description : To compare 2 sets of data (Data 01 : all users who are utilizing the licenses, Data 02 : all disabled users id AD). I there are match, it means the users can be removed and the licenses can be released. How To Do : Launch MS Excel, put the first group of data in Column A Put the second group of data in Column C Put the following formula in Cell B1 : Syntax : =IF(ISERROR(MATCH(A1,$C$1:$C$5,0)),
