I encounter an error while installing vSphere vCenter 4 on a Windows 2008 64 Bit vm. The vCenter installation refuses to install because port 80 is in use or disable. I took a few snapshots to give a visual of what I did to fix it.
1) I new that the vCenter would not go on with the installation because port 80 was in use and I didn’t want to change the port number, so I ran the command “netstat –anb” to see what ports were in use, see snapshot below.
2) So I found that port 80 was in use by an unknown service and it was displaying a weird message “Can not obtain ownership information”, see the snapshot above.
3) So the previous command did show me the service; so I ran “netstat –ano|more” to check the PID number, see snapshot below.
4) I ran Task Manager to compare PID 4 to all the running services and found nothing.
5) My next step was to do a google search of “what is blocking port 80” and got the following link http://forums.techarena.in/vista-security/1134326.htm.
6) The service that was blocking port 80 was “SQL Server Reporting Service”.
7) After disabling SQL Server Reporting Service I ran “netstat –ano|more” again and saw that port 80 was free again and my installation when on without any issues.
8) To install vCenter4 on a Win2k8 standard 64Bit server Microsoft SSRS needs to be disabled.
