I just had a new modem installed by my ISP. My DLNA device would not play and Windows said the IP was xxx.xxx.x.17. JRiver said the IP was xxx.xxx.x.22 I tried refresh Dynamic Entries and it still said .22 So, I rebooted JRiver and it still said .22 Then I closed IE and reopened and checked what Windows was saying the IP address was and it had updated to .22 and then I could stream to the DLNA.
So, the issue seems to be on the Windows side that Windows 10 is late to update the IP. JRiver has the correct IP and sends the call out but Windows 10 is (I am guessing here) redirecting the call from JRiver to the wrong IP.
Question - is there anything that can/should be set in Group Policy to force Windows to update connected IP's faster? This really does not seem to be a JRiver issue. But, it happens to me quite regularly because my ISP connection has been problematic and everytime I have to power the router down and reboot, the IP's of connected devices seem to change.
