Hello, This is my first post here, so bear with me. I'm looking for information about an exploit that starts searching for Netbios shares across random IP addresses. I have the following Code Red/Code Red II/Nimbda Policy-Map on my external router since August 17th, and this machine was installed post August 17th. http://www.cisco.com/warp/public/63/nbar_acl_codered.shtml This is an internal Windows NT 4.0 machine, patched sp6a and HFNETCHK states the following ---------------------------- SERVER01 ---------------------------- * WINDOWS NT4SERVER SP6a NOTE MS98-001 Q169556 NOTE MS99-036 Q155197 NOTE MS99-041 Q242294 NOTE MS01-022 Q296441 Patch NOT Found MS01-041 Q299444 Patch NOT Found MS01-048 Q305399 * Internet Information Server 4.0 NOTE MS99-025 Q184375 NOTE MS00-025 Q259799 NOTE MS00-028 Q260267 Patch NOT Found MS01-044 Q301625 * Internet Explorer 5.5 Gold Patch NOT Found MS00-093 Q279328 Patch NOT Found MS00-055 Q269368 Norton Corporate Antivirus 7.1 running with 12/6/01 virus data.
