The TCP/IP Registry Compatibility service may stop responding when a computer that is running Windows Vista or Windows Server 2008 is under high stress Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows
(http://windows.microsoft.com/en-us/windows/help/end-support-windows-xp-sp2-windows-vista-without-service-packs)
.
When a computer that is running Windows Vista or Windows Server 2008 is under high stress, the TCP/IP Registry Compatibility (Tcpipreg) service may stop responding. Or, a malfunction may occur in the service. Additionally, some applications that are related to the network do not function as expected.
For example, when you resume a Windows Vista-based computer from hibernation (S4) or from suspend (S3), a malfunction occurs in the Tcpipreg service. In this case, when you try to use the
net stop tcpipreg command to stop the Tcpipreg service, the command may stop responding.
