• VMware Management Web Services service starts without issues, but listens only on port 8005 and 8080

Environment

VMware vCenter Server 5.0.x
VMware vCenter Server 4.1.x
VMware vCenter Server 5.1.x
VMware vCenter Server 4.0.x
VMware vCenter Server 5.5.x

Cause

This issue may occur when port 8443 (default port of Management Web Services – HTTPS) is already used by another program.

Note: This issue may also occur in vCenter Server 5.1/5.5 when port 8003 is in use by another program. For more information, see TCP and UDP Ports required to access VMware vCenter Server, VMware ESXi and ESX hosts, and other network components (1012382).

Resolution

Verify that the VMware VirtualCenter Management Webservices is only listening on port 8005 and 8080 and identify which process or program is using port 8443:

• On vCenter Server, launch Command Prompt
• Type netstat -ano
• Note the PID of port 8005 and port 8080. The PIDs should be the same.
• Note the PID of port 8443. This is the PID of the process that is using port 8443.
• On vCenter Server, launch Task Manager.
• On Task Manager, select Processes tab
• Select View from the menu bar and then Select Columns option
• Check PID (Process Identifier) and click OK
• Find the match PID in the Task Manager's Process List
• PID we noted at step c should be Tomcat6.exe as process name
• PID we noted at step d should be the process that is listening on port 8443
  
  

Note: This issue may also occur in vCenter Server 5.1/5.5 when port 8003 is in use by another program. If you continue to experience issues, repeat the steps above, substituting port 8443 with port 8003.

• After the process name is found at step k, check if that process or program can be uninstalled or if its port can be changed to a different port number.

• Locate port number 8443 in each of above files and change it to the new port.
• Restart the VMware VirtualCenter Management Webservice. For instructions on restarting the these services, see Stopping, starting, or restarting the vCenter Server service (1003895).
