i know it is best to only have one firewall running but i had windows firewall and mcafee they where working fine together but then windows firewall turned of on its own and not let me turn it back on ever since it stoped i cant use shareaza as it not connect.

this is what it looks like

Some firewalls which you install will turn off the Windows firewall.

To enable the choice of On or Off again (referring to the above image) click Start, Run, type in services.msc and hit ENTER. Scroll down until you find Security Center. Right-click on it (Properties) and make sure it's Startup Type is set to AUTOMATIC.

Scroll down to Windows Firewall/Internet Connection Sharing (ICS) and do the same as above.

they are already set to automatic and i have even installed mcafee but still no luck any other ideas

i had windows firewall and mcafee

Bad idea...

Some firewalls which you install will turn off the Windows firewall.

I had problems with permanently turning Windows firewall on, after I uninstalled Norton firewall. Apparently, there were some Norton's registry leftovers, which were doing that mess.
Try cleaning your registry from any McAffee entries.
Also check "Add/Remove" listings for some other McAffee components.
My Norton had THREE entries in non-consecutive alphabetical locations.

thanks for the advice broni i have done that and then restarted comp but still cant turn it on.
you can close this thread i will just do a new install for the second time in the past 5 days

If you insist on running two firewalls you will continue to have problems.

The installation of a second firewall has most likely turned off the ability to turn on the Windows firewall. If you uninstall the second firewall, the ability to turn on the Windows firewall will probably return.
