User Logon Process - Logon Scripts Time (Alert)

Summary

Helps to identify a user whose logon scripts phase was very slow. This logon phase covers the time taken for the logon scripts to be executed.

Configuration

Overridable parameters:

Causes

Logon scripts can have a large impact on start time. Some of the most common ways that logon scripts increase logon times are:

• Slow or resource-intensive startup scripts (for example, those that move large numbers of files).

• Inefficient loops in scripts.

• Nested calls to different scripts.

Resolutions

To identify if this is a general issue on a delivery group, compare the user's load scripts time to the average time for all users in this Delivery Group for the last seven days.

See Delivery Group Average Logon Performance

Check also the User - Logon Activity (Troubleshooting) report to get information about this user's logons in the past.

Some scripts may complete a lot of actions, including calls to other scripts, long loops, mapping network drives, and others.

Optimize and merge logon scripts where possible. Windows Server 2008 introduced Group Policy Preferences, which when used can reduce, or in some cases eliminate, the need for logon scripts. When not using Group Policy Preferences, assign logon scripts to users via GPOs, rather than the AD User Account property setting.
