vCenter 4 installation and port 80 error

by julio on

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

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.

Yes, thanks! I don’t understand why MS doesn’t list SSRS as the program listening in netstat…
