I have a Small Business server 2000 running Exchange 2000. recently we realised that we may have been victims of spam and unwittingly processing 1000's of emails an hour. I have that problem under control right now, but Inetinfo.exe has 98% of CPU time all of the time.
I can't stop Exchange services (they time out) and I can't stop or kill Inetinfo.exe
Am I right in saying that I have a DoS and how can I take control over this issue?
I have SP3 for Exchange installed but nothing has changed....
Can anyone help Please?
