According to the Redmond company, the TCP/IP Registry Compatibility (Tcpipreg) service can malfunction on the latest Windows client and server operating systems. Microsoft pinpointed scenarios in which the platforms are under high stress associating them with the Tcpipreg service failing to respond. Microsoft also informed that the functionality issue would affect applications running on top of the impacted operating systems that need to connect to the network.
"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," the company explained.
Microsoft offers a hotfix designed to resolve the issue in Windows Vista RTM, SP1 and Windows Server 2008., but not an update, because the remedy is set up to deal only with the specific TCP/IP Registry Compatibility service problems. Microsoft plans to include the hotfix in Windows Vista Service Pack 2 and Windows Server 2008 Service Pack 2, without offering it to Vista RTM and SP1, and Windows Server 2008 operating systems through WU.
