I have a unique problem I could use your help with. We have several Dell Latitude D505 notebooks we use on our network. Since the last round of Windows Updates, on Tuesday May 5th, (we push them out to all workstations) these laptops will not connect to the domain. All other workstations will connect just fine. We're pretty sure it's linked to the updates since some of the notebooks worked all day *until* they downloaded and installed the udpates. If you look under My Network Places, under the LAN connection, it shows "Connected", but is only sending a few packets, nothing is being received. I asked our consultant to check out the switch and the MAC isn't showing on the switch itself which leads me to believe it's a problem on the notebook somewhere. Pings to itself yield a reply, but it can't see anything else. We've tried the obvious stuff like updating the NIC driver, ran a Windows repair, ran a repair on the Winsock and even went so far as to reformat and reinstall Windows XP. I don't see anything unusual in the Event Viewer, but could be overlooking something. I'm a loss and would really appreciate any insight...
Here's some pertinent scoop:
Windows XP Pro, SP2
Intell Pro/100 VE Network Connection Card
Plugged into a Cisco 2960 switch
Trying to attach to a Windows 2003 AD Domain
