Cannot clear ARP cache

[Smirnoff]

Sorry, this is also posted in 24hoursupport.helpdesk. I don't usually
double post but I have just found this NG and it seems more appropriate
to post here.


A friend asked me to check out his computer (XP, SP3) as he could no
longer access the internet.

Most of his Anti-malware programs were out of date, so I downloaded the
current definition updates on my machine (also new programs like
SuperAntiSpyware and Spybot S&D), saved them to disc and installed on
his machine.

Each found loads of malware and I continued running them until all
reported a clean bill of health.

Connected my Ethernet cable to his machine and LAN showed as
"connected". However, I still couldn't browse (with IE7 or Firefox).

Tried "Repair" and got the error message "Cannot clear ARP cache". Did
some checking and the advice was to "Run" :

netsh interface ip delete arpcache

Tried this a couple of times but the "black" box appeared for a second
or two and then closed.

Does this need to be run in safe mode? Could some of the anti-nasty
programs be blocking it?

Or, can anybody please suggest another solution?

Try running "netsh winsock reset" in an elevated command prompt.

I followed instructions in this link:

http://www.manast.com/2007/03/23/rectify-windows-xp-bug-cannot-clear-arp-cache/

and disabled "Routing and Remote Access" in Services.

I can now "Repair" the connection and ARP and DNS is flushed.

Still having problems though.

Please see same-header thread in 24hoursupport.helpdesk.

Thanks for your reply.
