SMTP Denial of Service

by scottmn . Updated 23 years, 1 month ago

Hello,
I have a Win 2K Small business Server box running Exchange 2000 and ISA. I have a problem where packets are constantly sent from the server creating a denial of service. The following entry is in the ISA Log several times and is suspicious.

c-ip – 127.0.0.1, cs-username – anonymous, c-agent – wininet, date – 2003-05-27, time – 01:27:01, s-computername – RBF01, cs-referred – RBF01, r-host – , R-ip – .com, r-port – 80, time-taken – 4500, cs-bytes – 134, cs-protocol – HTTP,
s-operation – GET, cs-uri http://.com/, s-object-source – Inet, sc-status – 11001.

I have the latest Symantec Antivirus Corporate Edition – Nothing found.

Have updated with the latest ISA Patches & Packs, Also same with Exchange, Win 2k Small Business Server??

Please help?
