Consider the following scenario:
- You have a Windows Server 2008 R2-based domain environment that has a certification authority (CA) and Remote Desktop certificates configured.
Note For more information about how to configure Remote Desktop certificates, go to the following Microsoft website:
- You have a Windows 7 Service Pack 1 (SP1)-based or Windows Server 2008 R2 SP1-based computer that uses Network Access Protection (NAP) 802.1X enforcement in the domain.
This issue occurs because of a delay in the initial setup of NAP 802.1X configuration when you start the computer. Before the connection from the computer to a domain controller is established, the Remote Desktop Configuration service checks whether the certificates need to be updated. However, the service cannot decode the certificate without domain controller connectivity. Therefore, a new certificate is requested to be generated.
Hotfix informationTo resolve this issue, install the hotfix on the Windows 7 SP1-based or Windows Server 2008 R2 SP1-based computer that uses NAP 802.1X. After you install this hotfix, a ConnectDCTimeoutregistry entry is created under the following registry subkey:
\HKEY_LOCAL_MACHINE\ System\CurrentControlSet\Control\Terminal ServerYou can configure the poll timeout for the domain controller connectivity check by configuring the ConnectDCTimeoutregistry entry.
- The default DWORD value of the ConnectDCTimeoutregistry entry is 20000(20 seconds).
- The minimum DWORD value of the registry entry is 0.
Note Under this configuration, the domain controller connectivity check is performed immediately.
- The maximum DWORD value of the registry entry is 600000(10 minutes).
Note If you set a value that is greater than 600000, the registry entry still uses 600000 as the configuration.
