We have similar issues in our library, and haven't found a solution yet. We are a Meru shop.
Users attempting to log on to laptops that are members of the domain get "Unable to find a logon server" errors when the wireless net in the library is being heavily utilized. We are using a Vista SSO GPO configured to first authenticate users to the wireless network and then authenticate them to the domain. One hack we've found is to reboot the machine and then don't attempt to login (don't hit ctrl-alt-del) until the screen saver starts. We don't think it's an wireless issue because Mac's and Linux systems don't have problems getting authenticated to the wireless network. -Neil -- Neil Johnson Network Engineer Information Technology Services The University of Iowa Work: 319 384-0938 Mobile: 319 540-2081 Fax: 319 355-2618 E-mail/MSN: neil-john...@uiowa.edu From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of Jason Appah Sent: Friday, May 15, 2009 1:01 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Enforcing and Ensuring Machine Auth 802.1x At our little campus we have about 100 computers that are pure wireless workstations provided in the library for student use. From time to time they will refuse to machine auth to the network. Typically they are reported after the fact as the student will bounce from workstation to workstation until they find a "Hot" one. Troubleshooting: We have tried JAMAP (Just add more access points). (for a stretch there we had 36 to 50 people, including wireless workstations on a single access point). Modifying the power settings so the machines never sleep. Updating drivers for the mix of Broadcom, intel and Linksys wireless cards. All to no avail. We are an all aruba shop and are quite pleased with their entire line, the system never bogs, higgs or given us any hint of trouble just the 802.1x problem. The problem is difficult because there are so many workstations and that they don't do it on any predicable scale. So..... any tips for 802.1x machine auth? Thanks!
