Symptoms

Consider the following scenario:

  • You have a computer that is running one of the following operating systems:

    • Windows Vista Service Pack 2 (SP2)

    • Windows Server 2008 Service Pack 2 (SP2)

    • Windows 7 Service Pack 1 (SP1)

    • Windows Server 2008 R2 Service Pack 1 (SP1)

    The computer is a member of a domain.

  • You configure users to apply multiple Group Policy objects (GPOs) when they log on to the domain from the computer. For example, domain level policies, organization unit level policies or local computer policies.

  • These GPOs contain the following Group Policy, each with a different setting:

    User Configuration\Administrative Templates\System\User Profiles\Limit profile size

In this scenario, the Profile Quota Manager tool (Proquota.exe) may receive incorrect profile quota settings. This behavior causes data loss if the incorrect quota size that is actually applied is too small.

Cause

This issue occurs because the Profile Quota Manager tool (Proquota.exe) has a hard-coded time limitation (2 seconds) to wait for Group Policy processing. If Group Policy processing does not finish within 2 seconds, the Proquota.exe process reads the profile quota size without waiting for the final quota size information.

Resolution
