OK...making some progress here. Note: Windows Firewall and AV on the client are on. Same with "server" (this machine).
Overall - I made four changes...highlighted in bold...
1. First - while testing Jim's suggestions to input
http://192.168.0.191:52199/LibraryServer/ on the client - I found IE9 (As installed by the OS install) was taking like 30 seconds to start. Found a tip on the web to go to Internet Options->Connections Tab->LAN Settings and
uncheck Automatically Detect Settings. IE starts up with light speed after taking this off.
2. Then I fired up another box (that I also thought ran IE9) so I could check it's settings. This box booted up and it was then that I found out it had been upgraded via Windows Update to IE10. Checked it - starts instantly.
3. While on this box - which is also an MC "client" - I decided to fired up MC (18.0.175 - Stable) and it instantly connected to the Media Server (This machine) - with no delays
4. Seeing how nice IE 10 operated on this box -
I decided to upgrade the HTPC to IE10 as well.5. Over on the HTPC (via RDP) ran Windows Update and let it do it's thing...and then let the box "reboot" itself
6. After I gave it a few moments - I went back in via Remote Desktop
7. Imagine my surprise - MC auto started - right into Theater Mode and was ready to go! (No errors)
8. I then
updated the version of MC on here to 18.0.1889. And - for kicks - per Marko -
I added the entire JRiver folder in AppData\Roaming to the NOD32 exclusion listWhat role does IE play in all of this? Could the AV exclusion addition have something to do with it?
Update: HTPC errors again just moments ago via RDP after letting it sit for 10 minutes or so. So not quite there yet....it - as usual - does connect on the second try.
