Bypass traverse checking windows xp

If you use access—based enumeration, users cannot see any folder or file to which they do not have access. For more info about this feature, see Access-based Enumeration. The Windows operating systems and many applications were designed with the expectation that anyone who can legitimately access the computer will have this user right. Therefore, we recommend that you thoroughly test any changes to assignments of the Bypass traverse checking user right before you make such changes to production systems.

We recommend that you leave this policy setting at its default configuration. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode. Implications of limiting anonymous access With the default denial of anonymous user access, it is easier for administrators to configure a secure system. Bypass traverse checking for anonymous users The procedure in this section applies to Windows 7 and Windows Vista.

To bypass traverse checking for anonymous users Click Start , type gpedit. Click Add User or Group. Click Check Names to verify that your entry is valid, and then click OK. Note There is no command-line method for this procedure.

The Everyone group is generally removed in favor of the Authenticated Users group. If the Everyone group is removed, the Authenticated Users group must be granted this user right.

Windows NT 4. Therefore, when you remove the Everyone group from Windows NT 4. All Microsoft network operating systems: User Account authentication from remote network client computers will fail unless the user or a security group that the user is a member of has been granted this user right. All Microsoft network operating systems: Account authentication from remote network clients will fail unless the account or a security group the account is a member of has been granted this user right.

This scenario applies to user accounts, to computer accounts, and to service accounts. All Microsoft network operating systems: Removing all accounts from this user right will prevent any account from logging on to the domain or from accessing network resources. If computed groups such as Enterprise Domain Controllers, Everyone, or Authenticated Users are removed, you must explicitly grant this user right to accounts or to security groups that the account is a member of to access remote computers over the network.

This scenario applies to all user accounts, to all computer accounts, and to all service accounts. All Microsoft network operating systems: The local administrator account uses a "blank" password.

Network connectivity with blank passwords is not permitted for administrator accounts in a domain environment. With this configuration, you can expect to receive an "Access Denied" error message. Examples of local logon operations include administrators who are logging on to the consoles of member computers, or domain controllers throughout the enterprise and domain users who are logging on to member computers to access their desktops by using non-privileged accounts.

Users who use a Remote Desktop connection or Terminal Services must have the Allow log on locally user right on destination computers that are running Windows or Windows XP because these logon modes are considered local to the hosting computer. Users who are logging on to a server that has Terminal Server enabled and who do not have this user right can still start a remote interactive session in Windows Server domains if they have the Allow logon through Terminal Services user right.

Removing administrative security groups, including Account Operators, Backup Operators, Print Operators or Server Operators, and the built-in Administrators group from the default domain controller's policy. Removing service accounts that are used by components and by programs on member computers and on domain controllers in the domain from the default domain controller's policy.

Removing service accounts that are defined in the local Security Accounts Manager SAM database of member computers or of workgroup computers. Removing non-built-in administrative accounts that are authenticating over Terminal Services that is running on a domain controller. Adding all user accounts in the domain explicitly or implicitly through the Everyone group to the Deny logon locally logon right.

This configuration will prevent users from logging on to any member computer or to any domain controller in the domain. Users must have the Allow log on locally user right to access the console or the desktop of a workgroup computer, a member computer, or a domain controller. Users must have this user right to log on over a Terminal Services session that is running on a Window based member computer or domain controller.

Failure to restrict console access to legitimate user accounts could result in unauthorized users downloading and executing malicious code to change their user rights. Removal of the Allow log on locally user right prevents unauthorized logons on the consoles of computers, such as domain controllers or application servers.

Removal of this logon right prevents non-domain accounts from logging on at the console of member computers in the domain. Windows terminal servers: The Allow log on locally user right is required for users to log on to Windows terminal servers. Background The Bypass traverse checking user right allows the user to browse through folders in the NTFS file system or in the registry without checking for the Traverse Folder special access permission.

The Bypass traverse checking user right does not allow the user to list the contents of a folder. It allows the user to traverse only its folders. Removing non-administrative accounts that log on to Windows based Terminal Services computers or Windows Server based Terminal Services computers that do not have permissions to access files and folders in the file system. Removing the Everyone group from the list of security principals who have this user right by default.

Windows operating systems, and also many programs, are designed with the expectation that anyone who can legitimately access the computer will have the Bypass traverse checking user right. Therefore, removing the Everyone group from the list of security principals who have this user right by default could lead to operating system instability or to program failure. It is better that you leave this setting at its default.

Reasons to grant this user right The default setting for the Bypass traverse checking user right is to allow anyone to bypass traverse checking. For experienced Windows system administrators, this is the expected behavior, and they configure file system access control lists SACLs accordingly. The only scenario where the default configuration may lead to a mishap is if the administrator who configures permissions does not understand the behavior and expects that users who cannot access a parent folder will not be able to access the contents of any child folders.

Reasons to remove this user right To try to prevent access to the files or the folders in the file system, organizations that are very concerned about security may be tempted to remove the Everyone group, or even the Users group, from the list of groups that have the Bypass traverse checking user right.

Windows , Windows Server If the Bypass traverse checking user right is removed or is misconfigured on computers that are running Windows or Windows Server , Group Policy settings in the SYVOL folder will not replicate between domain controllers in the domain. Windows , Windows XP Professional, Windows Server Computers that are running Windows , Windows XP Professional, or Windows Server will log events and and will not be able to apply computer policy and user policy when the required file system permissions are removed from the SYSVOL tree if the Bypass traverse checking user right is removed or is misconfigured.

For more information, click the following article number to view the article in the Microsoft Knowledge Base:. Windows , Windows Server On computers that are running Windows or Windows Server , the Quota tab in Windows Explorer will disappear when you view properties on a volume. Windows Non-administrators who log on to a Windows terminal server may receive the following error message:.

The application failed to initialize properly 0xc click OK to terminate the app. If you remove this user right, when a file is copied from a Windows client or from a Macintosh client to a Windows NT 4. Outlook Web Access: Non-administrators will not be able to log on to Microsoft Outlook Web Access, and they will receive an "Access Denied" error message if they are not granted the Bypass traverse checking user right.

The following list identifies a security setting, and the nested list provides a description about the security setting, identifies configuration settings that may cause issues, describes why you should apply the security setting, and then describes reasons why you may want to remove the security setting. The nested list then provides a symbolic name for the security setting and the registry path of the security setting. Finally, examples are provided of compatibility issues that may occur when the security setting is configured.

The Audit: Shut down system immediately if unable to log security audits setting determines whether the system shuts down if you cannot log security events. If the auditing system fails, the system is shut down, and a Stop error message appears. If the computer cannot record events to the security log, critical evidence or important troubleshooting information may not be available for review after a security incident. Risky configuration The following is a harmful configuration setting: The Audit: Shut down system immediately if unable to log security audits setting is turned on, and the size of the security event log is constrained by the Do not overwrite events clear log manually option, the Overwrite Events as needed option, or the Overwrite Events older than number days option in Event Viewer.

Reasons to enable this setting If the computer cannot record events to the security log, critical evidence or important troubleshooting information may not be available for review after a security incident. Enabling the Audit: Shut down system immediately if unable to log security audits setting stops the system if a security audit cannot be logged for any reason.

Typically, an event cannot be logged when the security audit log is full and when its specified retention method is either the Do not overwrite events clear log manually option or the Overwrite Events older than number days option. The administrative burden of enabling the Audit: Shut down system immediately if unable to log security audits setting can be very high, especially if you also turn on the Do not overwrite events clear log manually option for the security log.

This setting provides for individual accountability of operator actions. For example, an administrator could reset permissions on all users, computers, and groups in an organizational unit OU where auditing was enabled by using the built-in administrator account or other shared account and then deny that they reset such permissions.

However, enabling the setting does reduce the robustness of the system because a server may be forced to shut down by overwhelming it with logon events and with other security events that are written to the security log. Additionally, because the shutdown is not graceful, irreparable damage to the operating system, programs, or data may result. Windows Because of a bug, computers that are running the original released version of Windows , Windows SP1, Windows SP2, or Windows Server SP3 may stop logging events before the size that is specified in the Maximum log size option for the security event log is reached.

Make sure that your Windows domain controllers have Windows Service Pack 4 installed before you consider enabling this setting.

Windows , Windows Server Computers that are running Windows or Windows Server may stop responding and then may spontaneously restart if the Audit: Shut down system immediately if unable to log security audits setting is turned on, the security log is full, and an existing event log entry cannot be overwritten. When the computer restarts, the following Stop error message appears:. To recover, an administrator must log on, archive the security log optional , clear the security log, and then reset this option optional and as-needed.

Windows On Windows based computers, non-administrators will not be able to log on to remote access servers, and they will receive an error message that is similar to the following:. Windows On Windows domain controllers, Active Directory replication will fail, and an "Access Denied" message will appear if the security event log is full.

Microsoft Exchange Servers that are running Exchange will not be able to mount the information store database, and event will be registered in the event log. Outlook, Outlook Web Access: Non-administrators will not be able to access their mail through Microsoft Outlook or through Microsoft Outlook Web Access, and they will receive a error. The possible values for this policy setting are as follows:.

None: Data signing is not required to bind with the server. If the client requests data signing, the server supports it.

Applying the Windows or the Windows Server Hisecdc. Applying the Windows or the Windows Server Hisecws. Reasons to enable this setting Unsigned network traffic is susceptible to man-in-the-middle attacks where an intruder captures packets between the client and the server, modifies the packets, and then forwards them to the server. You can lower this risk in a corporate network by implementing strong physical security measures to help protect the network infrastructure.

Internet Protocol security IPSec authentication header mode can help prevent man-in-the-middle attacks. Authentication header mode performs mutual authentication and packet integrity for IP traffic. Clients that do not support LDAP signing will not be able to carry out LDAP queries against domain controllers and against global catalogs if NTLM authentication is negotiated and if the correct service packs are not installed on Windows domain controllers.

Network traces of LDAP traffic between clients and servers will be encrypted. This makes it difficult to examine LDAP conversations.

The Domain member: Require strong Windows or later session key setting determines whether a secure channel can be established with a domain controller that cannot encrypt secure channel traffic with a strong, bit session key.

Enabling this setting prevents establishing a secure channel with any domain controller that cannot encrypt secure channel data with a strong key. Disabling this setting allows bit session keys. Before you can enable this setting on a member workstation or on a server, all domain controllers in the domain that the member belongs to must be able to encrypt secure channel data with a strong, bit key.

This means that all such domain controllers must be running Windows or later. Risky configuration Enabling the Domain member: Require strong Windows or later session key setting is a harmful configuration setting. Session keys that are used to establish secure channel communications between member computers and domain controllers are much stronger in Windows than they are in earlier versions of Microsoft operating systems.

When it's possible, it is a good idea to take advantage of these stronger session keys to help protect secure channel communications from eavesdropping and from session hijacking network attacks. Eavesdropping is a form of malicious attack where network data is read or is altered in transit. The data can be modified to hide or to change the sender, or to redirect it.

Important A computer that is running Windows Server R2 or Windows 7 supports only strong keys when secure channels are used. This restriction prevents a trust between any Windows NT 4. Additionally, this restriction blocks the Windows NT 4. Reasons to disable this setting The domain contains member computers that are running operating systems other than Windows , Windows XP, or Windows Server Examples of compatibility problems Windows NT 4.
