There is nothing in the Server Event logs if that is where you are talking about.
I'm not sure what to check on the DHCP config. There haven't been any changes made and everyone else is fine. Here's what I did: I deleted the ip entry for this computer in DHCP and DNS, put back to dynamic ip, and for the last 4 hours it has been steady as a rock using its new ip address. That was a lot of head banging for this. Go figure? We've had lots of issues like this in the past where we've gone as far as changing the mb. Maybe this is all we will need to do the next time. Hope this helps someone else. Paul ________________________________ From: Miller Bonnie L.

MS has a patch now that turns most of it off for you, but I've found the reg entries to be the sure way to go if you want to be absolutely positive-can post if you need them. You might also want to check out your DHCP server and config since the static address seems to be working better-might be that the server logs are showing something important.

I gave this machine a static ip and so far it's working. Over 5 minutes now. Paul ________________________________ From: Miller Bonnie L.

Are these features supported/enabled somehow on XP (or Vista for Matt) or in the Broadcom drivers? I haven't looked at the newer desktop/laptop machines to see if this is an issue, and we use custom images anyway, so it wouldn't necessarily be there. I also haven't checked the XP SP3 release notes yet to see if they were included. -Bonnie From: Paul Everett [mailto:[EMAIL PROTECTED] Sent: Thursday, May 29, 2008 8:15 AM To: MS-Exchange Admin Issues Subject: RE: Dell laptop losing connectivity on network That sucks, but it's not my issue. We're non profit also so I'll remember that if we get Vista Home donated.

Broadcom adapter and Vista have some serious issues. I got a bunch of machines with Vista home dumped on me, Nonprofit. They had VOL Lic. and SA. We loaded vista business and the exact problem occurred. One added twist, they could surf the web all day but as soon as they connected to a network share or opened outlook the nic would shut down. Checked with MS, they pointed me to a couple of reg hacks that didn't work. Then called HP and got the run around for three days and finally got the answer. The workstations were sold with Vista Home. They are not supported with any other operating system period. They will not work with any other OS. Please return them to your vendor and purchase suitable machines.

CFee ________________________________ From: Paul Everett [mailto:[EMAIL PROTECTED] Sent: Thursday, May 29, 2008 09:37 To: MS-Exchange Admin Issues Subject: Dell laptop losing connectivity on network I have a Latitude D620 that started having connectivity issues. It will work just after it's turned on for about 5 minutes and then no network anything (local or Internet). Sometimes it will spontaneously start working again, but usually not. Sometimes if I "repair the local area connection" it will work, but usually that fails also. If I "disable"/"re-enable" the adapter it will always work, but only for a short period of time. When it is happening, I can ping the machine and get a mixture of "replys" and "timeouts". The only error in the error logs is when the "repair the local area connection" fails. I get event id 1003 from dhcp saying, "....unable to renew address from the network..... The following error occurred: The semaphore timeout period has expired. Your computer will try to continue to try and obtain an address............" The Dell tech thought it sounds like a software issue and we tried everything. Reinstalling the nic driver, stopping unnecessary services, ruling out cabling issues, etc. Finally he suggested, for no specific reason, to try the laptop outside of our network. So, I took it home last night and low and behold it worked fine without having any connectivity issues. I was using the same Domain user account. I would love to have some ideas on what may be going on or how to fix this. I have other laptops just like this and they are not having any issues,... yet. Thank you, Paul Everett IS Dept.
