Not sure if it is the right place to ask the question..

I have a following issue

On my desktop computer I can't access internet. Precisely, i can't ping router. However I can ping other machines on local network and i'm getting IP from DHCP located on the same router.

In router log messages I found "Saturday November 21, 2009 14:10:07 Block MY_MAC-AB-A3-5E because no D flag"

I failed to find anything interesting in google.

Any ideas? (How make desktop add D flag to packets or stop router blocking traffic)

Desktop is running on Windows XP arp -a says that machine doesn't now MAC of router, however setting it to be static doesn't help either. Router is D-Link DI-524 I used to have internet on that machine, it stooped working recently, however i can't thing of anything that could cause that.

you right SO is not the correct place for your question, place in on serverfault.com –  Artem Barger Dec 3 '09 at 14:16
    
Try doing a factory reset of the router, and then try again. –  trip0d199 Dec 3 '09 at 17:08
