DOCUMENT:Q198516 28-FEB-1999 [winnt] TITLE :WLBS Uses Port 2504 for Remote Control PRODUCT :Microsoft Windows NT PROD/VER:winnt:4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server, Enterprise Edition version 4.0 - Microsoft Windows NT Server version 4.0 - Microsoft Windows NT Load Balancing Service ------------------------------------------------------------------------------- SUMMARY ======= Window NT Load Balancing Service cluster control program (WLBS.exe) allows you start, stop, and query the cluster from any networked Windows NT system. You can control all cluster hosts with one command, or you can control them individually. Certain actions, such as modifying parameters, can only be performed on the cluster hosts. Because it is a console-based application, this program can be incorporated into scripts used for system management. The command line for WLBS.exe has the following form: WLBS [[:] []] The control program has full password protection to prevent unauthorized access. By default, WLBS.exe will send remote control requests to UDP port 2504. MORE INFORMATION ================ WLBS uses UDP port number 2504 for receiving remote control requests, while Convoy used port 1717. By default, WLBS.exe will send remote control requests to port 2504 and will not be able to control mixed Convoy/WLBS clusters. Please note that, for backward compatibility, WLBS hosts will still respond to remote control requests on port 1717 in addition to the new port 2504 if Convoy hosts are detected as part of the cluster.
