Hi,
don't know about the nshield.log analysis, we have to wait for Zdenek on this. However, it might be helpful to have a trace of the traffic that is causing the problems.
Could you try to record a packet dump from the session?
There are two options:
1. Wireshark - for those who like it and use it (like me). However, officially not yet supported on Windows8, if you have WireSharp already installed, please record the packet dump with it.
2. Microsoft Network Monitor
Let me describe the steps for NM:
1. download Network Monitor here:
http://www.microsoft.com/en-us/download/details.aspx?id=48652. select appropriate version based on your os version (32bit or 64bit)
3. download to your PC, and run the installer
4. Confirm YES and NEXT during the installer prompts.
5. The installation has to parts, Network Monitor and Parsers - both should complete easily, ending with a NM shortcut on the desktop
6. After the installation is completed - you have to logout and login again before using the program.
7. Log in again, open Network monitor on the desktop
8. Click "New Capture"
9. New tab opens, click the "Start" button on the taskbar.
10. Do the traffic that causes problems -- such as accessing your router.
11. After the problem manifests itself, click stop to terminate recording.
12. choose save-as and save the capture into file.
13. upload the file or send me a link via e-mail
To uninstall, use control panel/ Program and Features. Uninstall both "Microsoft Network Monitor" and "Microsoft Network Monitor Parsers". Reboot is not needed.
One more question: does the problem vanish after turning Network Shield off? Or do you have to fiddle with other providers as well (such as WebShield).
Thanks.
Lukas.
