On a computer that runs Windows 2000 Server, when you view the Active Directory Sites and Services snap-in for Microsoft Management Console (MMC), you see numerous duplicate connections that were created over a period of time. However, only one of those connections is in use.
This behavior can occur because of how the Knowledge Consistency Checker (KCC) works.
The KCC is responsible for choosing bridgehead servers and creating connection objects as appropriate. If the KCC determines that one or more specific network connections must be replicated and the manually chosen bridgehead server is unable to host a connection into or out of that site, the KCC erroneously generates an additional connection each time it runs, at 15-minute intervals by default.
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
This problem was first corrected in Windows 2000 Service Pack 2.
The KCC in Windows 2000 designates which servers perform the role of bridgehead server. This process is based on several criteria. It is best to let the KCC choose which computers will function as bridgehead servers.
