Losing "Preferred Networks" on GPO-controlled wireless clients

[iLinkTech]

Hi,

Having this problem on a fairly frequent basis - XPSP2 clients w/ 3Com OfficeConnect USB wireless adapters. Wireless settings (preferred networks, 802.1x, etc) all controlled via GPO on OU that computers reside in and no higher level wireless policies.

Whenever the IAS boxes are rebooted (Windows Updates, etc), the wireless clients lose the preferred networks and other authentication information. The only way to make it work again is to connect to a wired network connection and then run gpupdate. After gpupdate, wireless is available again and wired connection can be removed.

Using EAP-TLS, AES encryption, 802.1x, etc on 802.11g AP's (3Com 7250) - SSID beaconing disabled.

Any thoughts - starting to irritate my users - thanks...

Does the certificate exchange have to happen again after rebooting? I don't know...can you set it to stay 'valid' for longer?

Hi,

Thanks for your reply - if that is possible, I'm not sure how to do it. I do notice AutoEnrollment errors on the clients when this issue occurs but I'm not sure if its a result of being off network too long or because there is no network connection.
