iis - Cannot bind to port 80, Microsoft-HTTPAPI/2.0 Lock -
so, i've been trying bind wowza media server port 80 on our fail-over production server, , i'm encountering else being bound port.
the process reports 'system' pid 4. after chasing myself around web while, found numerous indicators iis, mssql, microsoft's web deployment service, or branch cache service. after exploring of these options, couple more relate server, can none of these binding ip -- not intentionally anyway.
if stop iis server through iis manager, port frees - indicating me iis. after rifling through bindings somewhere around 6-8 times now, can beyond shadow of doubt, none of sites have defined bound ip address. counts mention there no longer 'default site' - before runs through anyone's head.
further, i've run 'netsh http show servicestate' , combed through list entries matching problem ip, , have found none.
i've changed 'system/currentcontrolset/http/listenonlylist' registry entry, no avail.
does have other suggestions locating whatever system process - related or reliant on iis - have me spinning?
if system (4) using port means http.sys using it. iis uses http.sys low level http. best way figure out why case run following command elevated command prompt , see process ids:
netsh http show servicestate view=requestq verbose=yes request queue name: request queue unnamed. version: 2.0 state: active request queue 503 verbosity level: basic max requests: 1000 number of active processes attached: 1 **process ids**: 1120 url groups:... and find in there right reservation, maybe like: http : // localhost:80/
iis register reservation request queue name using application pool name let figure out using it.
