PEAP 3rd party radius server (or CA) issue - KB885453

Hi,
I think that I am hitting the bug.
It is ok for not using wirelss zero (or the Intel PROSet) to login though.
So, I download the patch and it contains 2 files,
I installed in this order,
WindowsXP-KB885453-x86-enu.exe
WindowsXP-KB885453-x86-Symbols-enu.exe

I found that the latter one contains a file rastls.pdb (and that's it) under
symbols\sp2qfe\retail\dll folder. I don't know how it is related to the
former one (whether the former one can find this rastls.pdb file and use it
....)

I find similar folders of sp2qfe under
C:\Windows\SoftwareDistribution\Download\...
And I can't find the file rastls.pdb under these folders.

There is no way to uninstall the patch from the control panel.
There is no user guide for installing the patch.
And I am still can't login with the Intel PROSet.

Please advise.
Thanks in advance

Actually, I should put in this way. The cert that I am using is a radius
server self signed cert. I don't want to put this cert into every wireless
client.

For the Windows built-in wireless setting, I don't have to specify a
particular CA and it works.

For the Intel ProSet setting, I need to specify a CA or import the cert into
the client and then specify the radius server as the CA. It seems the not to
specify a CA option does not work.
