When you try to log on to the computer, Windows stops responding (hangs) at the "Applying computer settings" part of the logon process.
This problem may occur if the DomainName\Exchange Servers group is not assigned the Manage auditing and security log user right.
To resolve this problem, use one of the following methods:
Method 1: Run Setup /PrepareAD
Run the Setup /PrepareAD command from the Exchange Server CD to prepare the Active Directory directory service for Exchange Server 2010 or Exchange Server 2007. This command restores the Exchange Servere configuration in Active Directory. For more information about how to prepare Active Directory, see the "How to Prepare Active Directory and Domains" topic in Exchange Server Help. To view this Help topic, follow these steps for the appropriate program.
Exchange Server 2010
Start Exchange Server 2010 Help.
Click the Contents tab, expand Deployment, expand New Installation, expand Preparing to Deploy Exchange 2010, and then click How to Prepare Active Directory and Domains.
Exchange Server 2007
Start Exchange Server 2007 Help.
Click the Contents tab, expand Deployment, expand New Installation, expand Preparing to Deploy Exchange 2007, and then click How to Prepare Active Directory and Domains.
Method 2: Add the Exchange Servers group to the "Manage auditing and security log" policy
To add the Exchange Servers group to the Manage auditing and security log policy, follow these steps:
Log on to a domain controller by using an account that has administrative rights.
Click Start, point to Administrative Tools, and then click Domain Controller Security Policy.
In the Default Domain Controller Security Settings Microsoft Management Console (MMC) snap-in, expand Local Policies, and then click User Rights Assignment.
In the right pane, double-click Manage auditing and security log.
In the Manage auditing and security log Properties dialog box, click Add User or Group.
In the User and group names box, type DomainName\Exchange Servers, and then click OK two times.
Exit the Default Domain Controller Security Settings MMC snap-in, and then wait for this security setting to propagate across the domain controllers in the domain.
Restart the Microsoft Exchange Information Store service.
