I wanted to let you folks know about an issue with AVG and Zimbra desktop. I troubleshot with the fine folks at the free avg forum site.
I installed AVG froo V. 8.0 then installed Zimbra Desktop connecting to a ZCS server. Once installed, it seemed to be working and then got stuck and so i restarted the service and at boot up Zimbra desktop tells me connection refused to localhost:7633. I thought it was a firewall issue, which i was running the builtin firewall in windows. The following thread details what i needed to do to rectify the problem. Which was basically Zimbra desktop and AVg were not gracefull with each other when encountering a message file that was infected with a virus. My other PCs that were using the same email account and zimbra desktop but a different antivirus(trendmicro) did not have an issue.
