Did you recently change the IP address of your physical VMWARE host server? Are you having trouble getting into the web-based vmware console to manage your virtual machines? This post will help you solve a “503 Service Unavailable” error message.
I recently ran into this problem and soon realized that the “VMWARE Server Web Access” service had stopped due to the IP Change.
The solution is to simply start this service! You may notice a console window pops up and starts a tomcat process. Let this window run in the background. If you close it, then your service will stop again.
