Gpofix is a command-line utility in Microsoft Windows Server that can be used to repair damaged or corrupted Group Policy Objects (GPOs) in Active Directory. A Group Policy Object (GPO) is a collection of settings that define how a computer or user operates in an Active Directory domain.
When a GPO becomes damaged or corrupted, it may not apply the correct settings to computers or users, which can result in issues with system configuration and security. Gpofix is designed to restore the default GPOs in an Active Directory domain to their original state, which can help to fix these types of issues.
To use gpofix, follow these steps:
- Log on to a domain controller as a domain administrator or a member of the Domain Admins group.
- Open a Command Prompt window with administrative privileges.
- Type “gpofix” and press Enter.
Gpofix will prompt you to confirm that you want to proceed with the repair operation. Once you confirm, the utility will restore the default GPOs in the domain to their original state.
Here’s an example of how to use gpofix:
C:\> gpofix

Here's an explanation of the gpofix syntax with comments:
gpofix [/domain:<DomainName>] [/dc:<DCName>] [/user:<UserName>] [/password:<Password>]
/domain:<DomainName>: Specifies the domain where you want to repair the Group Policy Objects (GPOs). Replace <DomainName> with the name of the target domain. If this parameter is not specified, gpofix will repair the GPOs in the current domain.
/dc:<DCName>: Specifies the domain controller (DC) to be used for the repair operation. Replace <DCName> with the name of the target DC. If this parameter is not specified, gpofix will use the closest available DC.
/user:<UserName>: Specifies the username to be used for the repair operation. Replace <UserName> with the name of the user account that has permissions to repair GPOs. If this parameter is not specified, gpofix will use the credentials of the currently logged-on user.
/password:<Password>: Specifies the password to be used for the repair operation. Replace <Password> with the password for the specified user account.
Note: The /user and /password parameters are not required if you are logged in as a member of the Domain Admins group.
Here's an example of how to use gpofix to repair GPOs in a domain named "contoso.com":
gpofix /domain:contoso.com
This command repairs the GPOs in the "contoso.com" domain, using the default settings for the DC and user account.
Note: Gpofix restores the default domain GPOs to their original state, but it does not affect any GPOs that have been created by administrators or customized for specific purposes. Therefore, it is important to ensure that any customized GPOs are backed up before running gpofix to avoid losing any changes that have been made to them.
