One of my machines has started to get serious networking issues. This all started to happen suddenly although I am not aware of any specific changes made to the machine. It is running Windows 7.
Some of the symptoms that was not a problem before:
- ssh into the machine rarely works and when it does it might stop after some minute
- rdesktop to this machine shows similar symptoms as ssh, if you manage to get in it freezes after a short time, but usually you do not get in at all.
- nmap shows:
Note: Host seems down. If it is really up, but blocking our ping probes, try -PN. This worked fine before.
However connecting with vnc has no problems at all.
Googling around I have tried some tips, none working so far such as turning off RDC (remote differential compression), turning off firewall, turning off antivirus, turning off network auto tuning.
How can I find out what the problem is ?
