I have a windows vista SP1 PC and a windows XP SP2 PC connected on the same network.
The vista machine has ZA 8.0.085 and the XPmachine ZA 6.0.667.
When I Ping the vista PC from the XP PC I get packet loss - sometimes 25%, other times 50% - and occasionally no packet loss.
Turn-off ZA on Vista PC and I have no packet loss!
Does anybody have an idea what is happening ...?
