I changed my security template, and lost the ability for my wireless clients to authenticate. I use WAP, PEAP with certificates generated by my in house Windows 2003 cert server. Is there an example template somewhere of what security settings need to be applied. My IAS server is a DC. Currently my wireless clients see my wireless network, connect, but then they sit for an extended period of time attempting to "validate identity" eventually failing and the connection is ended. I can go back to my old template, but I would prefer to understand the security template better and what needs to be enabled / disabled in order to make this work. I have gone through the security wizard a number of times, and am not sure what I am missing. I would be happy to supply more information, as to my configuration, etc. All was working well, then I ran the security wizard in order to trouble shoot an LDAP issue I was having with another application - resolved that and lost my RPC for exchange and my authentication for my wireless. Corrected the RPC issue, but have not been able to figure out what is missing for WAP PEAP. Thanks.
