Yes, and what you can do right now is to check what happen if you plug the same pc directly to a switch instead of router. Maybe on your router there're some port "shutted down".

Did that already and it didn't work either.

 

I'm about to give up on this.

Really... No idea... Sorry.

 

I still think the problem may be the router...

I'm not sure if it is the router.

I got another router and I keep having the same problem.

 

But thanks a lot for your help, though.

Ok, that's starting to be annoying for me. I MUST know the hell what's happening on that network!

 

Install wireshark http://www.wireshark.org/download.html on your server. Set the IP-address mode to DHCP, save settings and DISABLE each interface on your server. Now start wireshark on the right interface (start capturing), and than enable the interface. You should see some packets captured by the program. Wait until windows tells you that you are not connected and then stop capturing. Now save the result and upload here (the extension is the same, I prefer the native extension of wireshark).

 

Thanks

Hello,

 

it ain't half as annoying for you as it is for me -)

I'd really like to use this damn PC.

 

Ok, here are the screenshots. Sorry for the bad quality, but my upload ratio is only 500k.

Sorry, can you upload the LOG FILE, (File > save as > PCAP file). With that screenshot I can see only the initial part.
