There are times when the services running under AOS are having different issues (wrong configurations, changed settings, etc).
One of the first items you want to look for when troubleshooting a service issue is making sure they are responding properly on the address you have registered.
So, just open a browser and navigate to: http://your_address:your_port/DynamicsAx/Services/service_you_validate (for instance I am just now testing http://your_address:your_port/DynamicsAx/Services/UserSessionService or http://your_address:your_port/DynamicsAx/Services/BIServices). You should get the WSDL response from the services. If you don't, and get a service unavailable then your service is not deployed.
