<div dir="ltr"><div>@Grace, I've tried that. And now I'm monitoring the ethernet interface on the Win7 side. I'm watching announces to the network by the side of Win7 machine, a few DHCP discover, a lot of MS-SEARCH * HTTP/1.1 and even more of NOTIFY * HTTP/1.1 packets. I'm not really sure about those info, but when I apply decodifications to ICMP or IGRP, I see a lot of "Unknown ICMP (obsolete or malformed)" packets. Should I think the WIn7 client isn't working properly?<br>
<br></div>And BTW, thanks all of you for your help!<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/2/26 Grace He <span dir="ltr"><<a href="mailto:ghe@ryerson.ca" target="_blank">ghe@ryerson.ca</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hector: try the following:<br>
1. disable both wired and wireless on your PC<br>
2. enable only wired connection on your PC<br>
3. make sure the dhcp server and PC are on the same network<br>
4. on PC: run "ipconfig" to ensure it has wired connection<br>
5. on PC: run "ipconfig /release", then "ipconfig /renew"<br>
6. on dhcp server: look into log to see if any dhcp request coming<br>
from PC's MAC address<br>
<br>
I don't believe the problem is with your dhcp server.<br>
<br>
Cheers,<br>
Grace<br>
