问题
I have IBM Notes 9.0.1 (Revision 20131022.1138) installed on my Windows 8.1. Whenever I start my Domino Designer and try to preview a page it does not show up. I tried to start the local HTTP process using the command nhttp.exe -preview but it gave me an error as:
HTTP Server: Error - Unable to Bind port 80, port may be in use or user needs net_privaddr privilege
Using the command of netstat -o I was able to find Toaster.exe process bound to 80. I disabled it using instructions from here. But still I am getting the same error. Now the netstat -o command does not show any process bound to port 80.
Taking reference from this discussion I even disabled my Windows firewall but I am still unable to get it to work.

Not sure if this will work - but have you tried changing the Web Preview port in Domino Designer -> Preferences -> Domino Designer -> Web Preview Port. Change it to 8080 or something other than 80 that's not being used and see if it works.
