Being working on a PoC with my buddies at ControlUp, we have been asked for an integration with ServiceNow to automatically create incidents for example. As there is not a real “integration”, I started to look at both product documentations to find a way to answer this question. As a member of the ControlUp Expert program, I do have access to an unlimited version of the product, so it was easy for me to test some customizations. The good thing […]

As you may know, some features of Director rely on WinRM and you have to configure it following this article http://support.citrix.com/article/CTX125243. In large Active Directory environment, the user security token that is used to authenticate the user to the server may be larger than 16 KB. This can occur when a user is a member of many security groups. However, WinRM has a 16 KB size limit for HTTP authorization requests. Therefore, WinRM does not accept HTTP authorization requests that use […]
During a site upgrade I forgot to add my admin account in the “Full Administrator” role… Before rolling back to the previous version, I’ve performed some tests and here is the result: Connect to SQL Server Retrieve an account with the correct role through the SQL query: SELECT Administrators.Sid FROM [DAS].[Rights] as Rights, [DAS].[Administrators] as Administrators, [DAS].[Roles] as Roles Where Rights.AdminId = Administrators.Id and Rights.RoleId = Roles.Id and Roles.Name = ‘Full Administrator’ Modify the SID find with the previous query or create a […]
During a loginVSI load testing scenario on physical servers, I’ve encountered a specific problem: around 170 to 180 users (with a 15 second logon rate), the XenApp server stops opening new session because of a CPU outage. After a couple of dozens of minutes, the server was returning to a more expected value (about 60% of CPU usage). After this pause, the server is re-performing well and new sessions could connect without any problem. During this CPU peak period, the […]

Un petit post au sujet d’un problème lors de l’accès aux stratégies (ordinateurs et/ou utilisateurs). Le message d’erreur suivant apparaît lorsque l’on essaye d’afficher les stratégies : De plus, il est impossible de créer et/ou modifier une stratégie. Ce problème est dû à une corruption de la partie Policies du DataStore et il est possible de remettre à zéro les stratégies via une requête SQL. Par contre, il m’a été impossible de faire un export via PowerShell des stratégies, il a […]
Un « petit » bug sur le service Message Queuing (MSMQ) empêche l’enregistrement des sessions via SmartAuditor. La raison est que le service MSMQ ne se bind pas sur l’adresse IP du serveur mais sur l’adresse de loopback : Un workaround consiste à redémarrer le service MSMQ pour obtenir le bon binding : Un patch est disponible chez Microsoft (http://support.microsoft.com/kb/2554746) mais uniquement pour Vista/Windows 2008. Il faut passer un appel au support Microsoft pour obtenir la version Windows 2008 R2 ++ Sam
