When I try to connect NLBMgr.exe to my clustername it prompts for credentials and I cannot manage the cluster. If I connect NLBMgr to an individual node it works fine. It hasnt always behaved this way. <br />
I tried connecting to CLUSTER12.URL.COM(FQDN of Cluster), and no luck. I can connect no problem to CLUSTERNODE1. Or if I connect to CLUSTERNODE2.<br />
Any suggestions?

Exchange 2007 CA Servers in NLB Cluster

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
