I recently disconnected an iMac from our LAN because I was told by our IT services that it was sending out a Denial of Service attack to another machine.
I was not aware that Mac's were suseptible to anything that would cause a DoS. Was I wrong in my thinking? What could be causing this and what should I do to fix it?
Thanks...

Hi evony72178,

Although I haven't used many Mac's, I do know that there are only a few virusses/bots written for it, and I don't know of any that can perform a DoS (sure, I could be wrong)

Please try connecting it directly to another computer (with a cross-cable) and analize the flowing traffic. If it looks like complete random garbage, it could be a storming NIC instead of a DoS, in that case, replace the NIC.

Otherwise, please check this page:

Greetings,

Run an up to date virus scan on the device.  This should be sufficient to remove any DoS tools installed on it.
