XADM: Active Directory Connector Setup Causes Lsass.exe to Use 100 Percent CPU (237434)
The information in this article applies to:
- Microsoft Exchange 2000 Server
This article was previously published under Q237434 SUMMARY
When you first install the Active Directory Connector (ADC), the Lsass.exe process consumes 95-100 percent of processor usage.
MORE INFORMATION
This behavior is to be expected.
The Local Security Authentication Server (Lsass.exe) process receives authentication requests from Winlogon and calls the appropriate authentication package to perform account verification and validation. When you install the ADC, for each modification made to the Windows 2000 Active Directory Schema, a call is made to Lsass.exe to verify that the ADC service account has the correct permissions necessary to modify the Active Directory Schema.
