Upgrade ACS 4.1 to 4.2

Unanswered Question
Oct 31st, 2008

We have 3 Windows2008 AD + 1 Windows 2003 AD, Cisco ACS4.1, Cisco WCS with 50 access point and we have using 802.1x PEAP MSChapV2 to authorized users and computers. Everything has worked okey for one year but today I upgrade with old settings ACS to version 4.2 and it seems to that workstations do not anymore authorize with AD. I get these e-mail messages all the time from ACS "Radiu server '193.143.235.43'(port 1812) is deactivated on WLAN 'Ker245'. (2 times)" and "Radius server '193.143.235.43'(port 1812) is deactivated on WLAN 'Ker245'. (2 times)" and when I check form ACS reports it says "Authetication session invalidated" and "host/XTE024.kernet.fi .. .. (Unknown) Authen session timed out: Challenge not provided by client" How should I continue to solve this problem?

I have this problem too.

I must also add that I still get these "Authen session timed out: Challenge not provided by client" messages from workstations time to time.

Hi,

I have installed patch 16 for 4.2 and now I am not getting this messages, so install patch 16 for 4.2, it will solve your problem.

Thanks,

AS
