- You have a client computer that is running Windows 7 or Windows Server 2008 R2 in a network environment.
- User accounts are configured to use roaming profiles when users log on to the computer from a remote site.
- You enable the following Group Policy setting to enable slow link detection for roaming profiles:Computer Configuration\Administrative Templates\System\User Profiles\Slow network connection timeout for user profiles
- You configure the Connection speed option and the Time option in the Group Policy setting.
- You log on to the client computer from a remote site by using a network connection. The network connection has a fast link speed to the profile server and has high network latency.
Note The high network latency causes the download speed on the computer to be slow.
Note This issue also occurs when you do not enable the Slow network connection timeout for user profiles Group Policy setting. When you do not enable the Group Policy setting, the computer uses the default settings for the Connection speed option and for the Time option.
Hotfix informationImportant This hotfix has been re-released to address an issue in which the digital signature on files produced and signed by Microsoft will expire prematurely, as described in Microsoft Security Advisory 2749655.
This hotfix also fixes a regression issue in the Profsvc.dll file after you install update 2775511. For more information about update 2775511, click the following article number to view the article in the Microsoft Knowledge Base:
After you install the hotfix that is described in this Microsoft Knowledge Base (KB) article on the client computer, the computer considers both the Time option and the Connection Speed option in the Slow network connection timeout for user profiles Group Policy setting. You can use the Time option to adjust network latency.
When you install the hotfix that is described in this KB article on the client computer, a new DWORD value named UseSMBBasedBandwidthAndLatency that has a value of 1 is added in the following registry subkey: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ProfSvc\Parameters
If you do not want the computer to consider network latency, set the value of the UseSMBBasedBandwidthAndLatency registry entry to 0.

Restart requirementYou must restart the computer after you apply this hotfix.
Hotfix replacement informationThis hotfix does not replace a previously released hotfix.
In the policy "Slow network connection timeout for user profiles" , the Time option has been found to be the most reliable option for measuring slow link for profiles. Using the connection speed does not always produce the desired effect due to the mechanism being dependent on SMB performance.
