The Windows Firewall has detected an application listening

The Windows Firewall has detected an application listening

I'm getting these critical alerts from a windows 2003 server. This server has both IIS and SQL 2000 (sp4) running. I've searched quite extensively but am unable to come up with any reasons for it. I don't have the "Windows Firewall"

ID=861 Source=Security Type=5 Message=The Windows Firewall has detected an application listening for incoming traffic. Name: - Path: C:\WINDOWS\system32\lsass.exe Process identifier: 420 User account
