Have you FailureLogon audit enabled on your DC's? If yes, you need to check source workstation that generate failure audits and remove it from network.[http://www.sysadmins.lv] As always enjoy the automation of tools within the Windows-based, .NET aware, WPF accessible, multi-processes on the same IP / Port usage, admin's automation tool, powershell.exe!

These are the log on my DC, but workstation name (INDUS) itself DC host name.Logon Failure: Reason: Account locked out User Name: pradeep.k.shukla Domain: hiplintranet Logon Type: 8 Logon Process: Advapi Authentication Package: Negotiate Workstation Name: INDUS Caller User Name: INDUS$ Caller Domain: HIPLINTRANET Caller Logon ID: (0x0,0x3E7) Caller Process ID: 5004 Transited Services: - Source Network Address: 203.88.21.199 Source Port: 1954, ThanksVikas

Your accounts are lockeddue passwordbrute force via your IIS server. As far as I understand, you have Basic authentication enabled only on your IIS server. Try to disable Basic Authentication and switch to Integrated (or something else) authentication.[http://www.sysadmins.lv] As always enjoy the automation of tools within the Windows-based, .NET aware, WPF accessible, multi-processes on the same IP / Port usage, admin's automation tool, powershell.exe!

OkTell me what will be the impact, to od this on my SBS 2003 , exchange hosted enviorment.and where should i have to change ?Thanks in advanceVikas Sagar

If you have Exchange server installed, perhaps you use OWA features. You need to open IIS management console, select properties of each your web site and change authentication level in Directory Security tab.[http://www.sysadmins.lv] As always enjoy the automation of tools within the Windows-based, .NET aware, WPF accessible, multi-processes on the same IP / Port usage, admin's automation tool, powershell.exe!
