Rejoining Windows Server 2003 – Hosting Exchange 2003

Hi, I have problem that my Exchange Server 2003 computer does not get the Windows Update Domain Policy applied on it. I note that on Control Panel, the options are still available to setup just as how it is on a stand alone computer. I pulled a report on the domain policy currently in effect on the server and it was found that under "Specify intranet Microsoft Update service location > intranet update service for detecting updates : (the port 8530) is not specified (This is my WSUS server). Similarly on "Set the intranet statistics server: it has (with no port 8530 specified. Please note that all my other servers and desktops are getting the policy applied fine and are set to the intranet host. With this I suspect that for some reason, the server is not communicating correctly with the domain controller. Hence I would like to know if there would be any problems I can encounter if I remove the server from the domain and rejoin it, with the hope to re-apply the domain policy upon rejoining? The server is: Windows Server 2003 STD, with Exchange Server 2003 STD. Regards Mduh

I would suggest 1st running trough these steps before considering rejoining to the domain, also 1st make sure that DNS is working perfectly and names does resolve from the specified server,

GPO does not apply to a specific user or computer

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

This topic explains the importance of correct Organizational Unit memberships and GPO linking and shows how to check these issues using GPMC and other tools.

GPOs are applied to a client only if they are linked to a site, domain, or OU to which the computer or the user at that computer belongs.

For troubleshooting purposes, you need a solid understanding of your organization’s Active Directory structure and the Group Policy inheritance and filtering rules. With this information and the Resultant Set of Policy (RSoP) functionality in Windows Server 2003 and Windows XP, you can manipulate your Active Directory structure and your Group Policy links and filters to deliver targeted settings to the users and computers in your organization. The same information is needed to troubleshoot situations where these manipulations produce an unexpected result.

Check Active Directory Users and Computers to see what site, domain, and OU the user and the computer are in.

In GPMC, expand the Active Directory containers that contain the affected client. In the navigation pane, scan the list of GPOs for each container for disabled links.

GPOs are filtered according to the Active Directory groups that the users and computers belong to. The Active Directory objects in which you place your Active Directory groups and the ways you group users or computers affect how GPOs can be distributed and applied.

Active Directory and FRS replication lag can affect either part of the GPO.

If you have an OU that contains other OUs and you remove Read permissions to the parent OU, then no policy will be processed by computers or users in that OU hierarchy.

If there are conflicting settings in the GPOs that apply to the client, they are resolved according to the Group Policy inheritance rules.
Adding a User or Computer to an OU

When a user or computer is added to an OU, two things need to happen before the GPOs that the new OU links to are applied to the client:

* The new OU assignment must be replicated to the client’s domain controller.

* After the replication is complete, you must either log off and log back on again if the user account moved to the new OU, or restart the computer if the computer moved to the new OU.
