Unable to access other computers on network
« on: July 27, 2010, 05:39:49 PM »
Hi there

We've recently upgraded computers [1] & [2] of our 6 computers to Avast Internet Security, and are now experiencing network issues. When switched on, the Avast firewall on appears to be blocking in/out communications with other computers on the network. If I temporarily disable the firewall, everything is fine and I can access the files on computer [2] via computer [1], and via the other network computers.

Computers are running XP Pro.
I have added the network internal IP range to the 'friends' list in the advanced firewall settings.
Windows Firewall is disabled.
Full virus/malware/spyware scans have been run on these computers and anything dodgy has been removed.

If this is the wrong forum to post in, I do apologise!

I have read through that, unable to find anything helpful apart from specifying the IP range as 'friends'. I've done this, but it hasn't helped.

Hi!

Just to have asked this… The correct IP-range..?

If Avast is on, does PING still work or is this blocked, too?

Definitely the correct IP range, I followed the IP range instructions in asyn's link, but of course altered to suit our network.

With Avast Firewall switched on, I tried pinging computer [1] from computer [2], but it failed, all requests timed out, 100% packet loss

No other anti-virus/firewall.

Computer [1] has Spybot S&D, but that isn't going to cause any problems.

Sometimes it did cause problems together with avast 5.x...

What is the 'correct' setting?
I checked and by default Windows Networking wasn't ticked, so I ticked it 'on' and set it to in/out

Hi ,with this rule enabled does things work now?
If it does I'd modify the rule "address" box to only your local network ip range.
hope that helps

Well, this is getting ridiculous - the only reply so far has been them requesting a hijackthis log - which I submitted 10 days ago! Still no response...
