Logon issues are part of the reality of any desktop virtualization environment. Since slow logons are rampant in virtual environments and have a negative impact on user experience and how VDI is perceived in the organization, it is important to minimize the slow logons to the lowest level possible.
Let’s explore common reasons for slow logons and offer best practices in order to troubleshoot them:
Slow logons are tricky to investigate. This is due to the fact that the logon process consists of a multitude of communication points and phases. These include:
Profile load time issues:
The list of products like persona management, Citrix User Profile manager and many other profile management tools is long. Third party profile management tools rose to fame due to the lack of functionality in Microsoft AD options. I won’t be covering those, even though using an adequate solution for profile management could reduce logon times.
How can you ensure that your profile load time is optimal?
Profile Management is Necessary
Group policy load time issues:
Manage your GPOs
Citrix Group policy (Citrix Environments only) issues:
Printer Mapping Effects on Logon time
Printer Mapping- Citrix has a comprehensive solution for printer mapping. Use it! In XenDesktop/XenApp, you can apply an intricate set of policies to your VDIXenApp environment. Policies like mapping default printers, making sure that the “Wait for printers to be created” policy is set to disabled, could save precious logon time.
Once the shell has loaded, the Startup apps start loading as well. Many apps wind up the startup folder by default when they’re installed. In Windows 7, you should open msconfig in order to disable those apps. In windows 10, simply open the Task Manager under the Startup tab:
To sum up
The Logon process is complex and includes multiple phases. I’ve tried to gather the most common and important best practices for each phase. The main point I tried to get across is that the list of reasons for slow logons is long. There are few musts like redirecting the profile folders into the correct network paths, reducing the GPOs to the minimum and so on, but in order to find the root cause for logon issues, comprehensive solutions and substantial tools of the like you can find in ControlUp, CAN HELP.
