The event log cannot function correctly unless proper file permissions are assigned to the log files. You might need to do the following:

• Assign permissions to the audit log files so that the service can write to them.

• Assign user write permissions to the folder where the audit log file is created.

To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.

To change permissions on files and folders:

• At the DHCP server, click Start, point to All programs, point to Accessories, and then click Windows Explorer.

• Navigate the directory tree to %windir%\System32\Dhcp, right-click the folder, click Properties, and then click the Security tab.

• Complete one of the following as needed:

• To set permissions for a group or user that does not appear in the Group or user names box, click Add, type the name of the group or user, and then click OK.

• To change or remove permissions from an existing group or user, click the name of the group or user.

• To allow or deny a permission, in the Permissions for User or Group box, select the Allow or Deny check box.

• To remove the group or user from the Group or user names box, click Remove.

Notes

• You can only set file and folder permissions on drives formatted to use NTFS.

• To change permissions, you must be the owner or have been granted permission by the owner to do so.

• Groups or users who are granted Full Control for a folder can delete files and subfolders within that folder, regardless of the permissions that protect the files and subfolders.

• If the check boxes under Permissions for User or Group are shaded or if the Remove button is unavailable, then the file or folder has inherited permissions from the parent folder.

• When adding a new user or group, by default, this user or group will have Read, Read and Execute, and List Folder Contents permissions.
