specs, can you tell us the exact error message you are receiving when your systems tells you that you need to clean your ARP cache?
The ARP cache is a table which keeps track of mappings between the
MAC addresses used on the
Data Link Layer and IP addresses used on the
Network Layer.
If you are interested in learning more, please refer to
What is ARP? and
What is the ARP Cache? Steps to Clean Your ARP Cache under Microsoft Windows
Click the <Start> button.
Click <Run>.
Type in "cmd" and press <RETURN>.
In the command shell which opens, type in "netsh interface ip delete arpcache" and press <RETURN>.
Your results should look like this:
Code:
C:\>netsh interface ip delete arpcache
Ok.
Next Steps if Simply Cleaning Your ARP Cache Fails
Occasionally, cleaning your ARP cache will fail because Microsoft Windows has managed to configure itself as a
router.
To workaround this bug in Microsoft Windows:
Click the <Start> button
Click the <Control Panel> button
Switch to "Classic View" if you are in "Category View"
Click <Administrative Tools>
Click <Computer Management>
Double-click <Services and Applications>
Double-click <Services>
Scroll down to <Routing and Remote Services>
Double-click <Routing and Remote Services>
Examine the "Startup Type"
The options are "Automatic", "Manual", and "Disabled"
Set the "Startup Type" to "Disabled"
Click the <OK> button
Now, clear your arp cache again. It should work this time with no error messages.
