Hi All,

I am currently using ISA 2006 to publish my OWA to the external world. Is there a way to configure the ISA 2006 to monitor the number of fail attempt generated? I mean for example, user1 tries to logon to OWA. If he treis to logon with a wrong password for more then 3 times then ISA will generate an email notifciation to the admin saying this? Just wondering.

Thanks

Without using an extra application, is there a way to track it? I know that the ISA logs won't be useful in this.How about on the exchange server? How about the event veiwer security logs? If we were to check the event viewer security logs it must be the one on the DC? Correct? Since ISA doesn't perform authentication but the DC? Do you guys know any tool or what event ID we should be aware of?I know this is a tedious job, but just trying to look for options.

Thanks.

Yep, failed logon events can be found in your Domain Controller security logs. This may help: http://technet.microsoft.com/en-us/library/cc671957(WS.10).aspx

A few more questions :
1) If I were to use AD authentication, is there a way that I adjust owa in ISA to stop authenticating a user for maybe 30 mins after 3 failed attempts? I do not want it to lock the account in the AD. Maybe the AD default lockout account is 5 times. 
2) Is there a different method to replace RSA? A cheaper solution.
3) ActiveSync connection, do they work on 2 factor authentication?  Anyway to get this done?

Thanks again for all your help.

A1: Collective LockoutGuard is designed to specifically provide this type of functionality.

A2: There are lots of cheaper 2FA solutions from other vendors, take your pick! RSA is still a good (albeit expensive) option IMHO.

A3: ActiveSync can be configured to support 2FA using RSA, but not sure about other vendor solutions.

Cheers

Thanks for your answer all this while.

How about Forefront UAG? Will it help on the AD part? How is Forefron UAG different from our ISA 2006 publishing rule?

Sorry for all the questions.

Forefront UAG does have independent failed logon protection which you can configure per trunk using the Maximum logon attempts setting. UAG then presents the user with an error and from memory you then need to restart the broswer to try again...

Does UAG creates alerts on failed logon? I mean if a user tries login on for 3 times then get the soft lock, will an alert appear in the event viewer or any part for the software? From the documentation, I know that lockoutguard does create an alert in the ISA alert screen when there is fail attempts.

I was testing UAG and it seems that after 3 fail login, if I would to clear cache and cookies and restart the browser or use a different browser I am able to create an account lockout. Is that correct?

Thanks.
