I've seen this when Windows has a mis-configured subnet mask. Remember, Windows defaults to 255.255.0.0 for a 172.16.x.x address, and many network admins forget and/or don't know to change it. Windows sends all sorts of broadcast stuff, and it'll all be sent to 172.16.255.255 if the mask is mis-configured.
(I found this out while troubleshooting why an ISDN line kept dialing - the router was routing all 172.16.255.255 packets to the 172.16.0.0/16 floating static because there was no 172.16.255.0/24 network, and the floating static was the longest match... Turned out to be mis-configured masks on random systems.) Good luck. --Wes Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=41091&t=41019 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
