I have had a look at our config, based on the fact we get the updates.
AVERTAlertsURL = http://myavert.avertlabs.com:8801/reportservice.asmx
From Memeory the ePO sevrer Java appliaction also connects to this service using SOAP.
Are you using a Proxy?
is there a special config entry for the AVERTAlertsURL in the EPO environment? If I use this AVERTAlertsURL in IE, I can access this site.
Yes I use the a proxy. The EPO-proxy configuration on our EPO 4.0 server is "use the IE settings" and in the IE proxy is configured.
What is SOAP? On the EPO server is also installed "Java 2 Runtime Environment, SE v1.4.2_17".
did you have a site firewall, perhaps you need to configure it to authorize myavert.
