Please wait for the Local Session Manager

I’ve built a lab to run some tests on Citrix XenApp. Since this is a lab environment I do not have enough resources to create dedicated machines for each role. Therefore I found it justified to create a virtualized domain controller (dc001.domain.local) with multiple roles and multi-homed (Boooohhh, I know). The machine is not only a domain controller but also has the DNS and DHCP role.

The following network interfaces are present on dc001.domain.local:

  • Local Area Connection 1 : 192.168.1.1/24
  • Local Area Connection 2:  192.168.2.1/24

The Citrix XenApp server is a dedicated physical machine with a single network interface:

  • Local Area Connection 1 : 192.168.1.2/24

After creating a published desktop I’ve tried to connect from a machine in the 192.168.1.0/24 subnet. The session keeps waiting with the message ‘Please wait for the Local Session Manager’.

VMware shared folders keep profiles in use

VMware Shared Folders

When Microsoft Windows systems are virtualized with VMware ESX or Workstation, WMware Tools is installed. When the VMware tools are installed with the Complete option, the shared folders option is enabled. This feature is not enabled when you install VMware tools with the Typical option.

The shared folder feature is not supported by ESX or GSX server and causes problems on Terminal Servers. The file hgfs.dat is opened by the VMware Tools with exclusive acces, which prevents the profile from getting deleted.

The impact of Silverlight on a virtual desktop

Silverlight Logo

A customer has a (virtualized) Citrix XenApp farm scaled for 1500 concurrent users. The environment is based on Windows Server 2003 Standard with Citrix XenApp 5 (migration to XenApp 6.x is scheduled).

A business critital web-application is re-developped and requires Microsoft Silverlight. Before implementing Silverlight the impact should be determined. A big concern is a decrease in the capacity of the farm, number of concurrent users the farm can handle.

To determine the impact of Silverlight I’ve done some tests, including a LoadTest.

Client File Security

In the Citrix ICA client, or XenApp Client Online plug-in, the access to your client drives is protected.
The first time you access your client drives the client will ask to allow (or disallow) the access. This message looks like this:

Stresstest your printer drivers

Written by Ingmar Verheij on November 6th, 2009. Posted in Performance testing, Printing

A few days ago I wrote an article about the issues with printer drivers in a multiuser environment. In this article I advised you to test you’re printer drivers in a acceptance environment, preferably with real users testing. This can be achieved with a LoadTest / StressTest tool like the Denamik LoadGen, which is free up to 25 users. And since testing with 10 users is enough to stress a driver, there’s no need to buy a license.

Today I would like to tell you how this is done, step-by-step.

The goal
We’re going to try to use the printer environment as realistic as possible, but where focusing on the worst case scenario. Because where trying to find out whether the printer driver is functioning correct when multiple users are printing, where going to simulate that a number of users are printing to printers using the same printer driver.
