On domain controllers, scesrv. This is the client-side interface or wrapper to scesrv. It is used by Setup to configure default system security and security of files, registry keys, and services installed by the Setup API. The command-line version of the security configuration and analysis user interfaces, secedit.
You use this tool to configure security settings in a Group Policy Object for a site, domain, or organizational unit. This is a permanent system database used for policy propagation including a table of persistent settings for rollback purposes. A user database is any database other than the system database created by administrators for the purposes of configuration or analysis of security. These are text files that contain declarative security settings. They are loaded into a database before configuration or analysis.
Group Policy security policies are stored in. For a domain-joined device, where Group Policy is administered, security settings are processed in conjunction with Group Policy.
Not all settings are configurable. When a computer starts and a user logs on, computer policy and user policy are applied according to the following sequence:. The network starts. An ordered list of Group Policy Objects is obtained for the device.
The list might depend on these factors:. Computer policy is applied. These are the settings under Computer Configuration from the gathered list. This is a synchronous process by default and occurs in the following order: local, site, domain, organizational unit, child organizational unit, and so on.
No user interface appears while computer policies are processed. Startup scripts run. This is hidden and synchronous by default; each script must complete or time out before the next one starts. The default time-out is seconds. You can use several policy settings to modify this behavior. After the user is validated, the user profile loads; it is governed by the policy settings that are in effect. An ordered list of Group Policy Objects is obtained for the user.
User policy is applied. These are the settings under User Configuration from the gathered list. This is synchronous by default and in the following order: local, site, domain, organizational unit, child organizational unit, and so on.
No user interface appears while user policies are processed. Logon scripts run. The user object script runs last. The policy setting information of a GPO is stored in the following two locations:. The Group Policy template is a file system folder that includes policy data specified by. Any Group Policy Objects that have been linked to the site are processed next. Processing is synchronous and in an order that you specify. Processing of multiple domain-linked Group Policy Objects is synchronous and in an order you speciy.
Group Policy Objects that are linked to the organizational unit that is highest in the Active Directory hierarchy are processed first, then Group Policy Objects that are linked to its child organizational unit, and so on.
Finally, the Group Policy Objects that are linked to the organizational unit that contains the user or device are processed. At the level of each organizational unit in the Active Directory hierarchy, one, many, or no Group Policy Objects can be linked. If several Group Policy Objects are linked to an organizational unit, their processing is synchronous and in an order that you specify.
This order means that the local Group Policy Object is processed first, and Group Policy Objects that are linked to the organizational unit of which the computer or user is a direct member are processed last, which overwrites the earlier Group Policy Objects. This is the default processing order and administrators can specify exceptions to this order. A Group Policy Object that is linked to a site, domain, or organizational unit not a local Group Policy Object can be set to Enforced with respect to that site, domain, or organizational unit, so that none of its policy settings can be overridden.
Try and not have more then 5 or 6 GPO's applied to a single client. Any higher then that can cause problems like this. What AV are you running? We've seen this when some AV clients try to either scan or update before login. We've even had to take it off some servers because reboots became ordeals. I have experienced this problem caused by Exchange being on a DC bad setup. We've seen this when there is network connectivity issues with our DCs. In fact, we had this issue just the other day when our core switch had a loose stacking cable on the back.
We started several constant pings to several of our servers and we would see occasional ping drops. Also, try looking for any errors on either the switch interface the DC is plugged into or specific PCs are using.
You might have a bad cable I've see it where someone makes a bad ethernet cable and it appears to function fine, but drops packets here and there.
Synthetic Development is an IT service provider. Registry based settings: Allows you to create a policy to administer operating system components and applications. Security settings: Allows you to set security options for users and computers to restrict them to run files based on path, hash, publisher criteria or URL zone.
Software restrictions: Allows you to create a policy that would restrict users running unwanted applications and protect computers against virus and hacking attacks. Software distribution and installation: Allows you to either assign or publish software application to domain users centrally with the help of a group policy. Roaming user profiles: Allows mobile users to see a familiar and consistent desktop environment on all the computers of the domain by storing their profile centrally on a server.
Internet Explorer maintenance: Allows administrators to manage the IE settings of the users' computers in a domain by setting the security zones, privacy settings and other parameters centrally with the help of group policy. Local Group Policies affect only the users who log in to the local machine but domain-based policies affect all the users of the domain. If you are creating domain-based policies then you can create policy at three levels: sites , domains and OUs. Besides, you have to make sure that each computer must belong to only one domain and only one site.
When a GPO is defined it is inherited by all the objects under it and is applied in a cumulative fashion successively starting from local computer to site, domain and each nested OU. For example if a GPO is created at domain level then it will affect all the domain members and all the OUs beneath it.
After applying all the policies in hierarchy, the end result of the policy that takes effect on a user or a computer is called the Resultant Set of Policy RSoP. It provides a unified view of local computer, sites, domains and OUs organizational units. You can have the following tools in a single console:. A group policy can be configured for computers or users or both, as shown here:.
The Group Policy editor can be run using the gpedit. Both the policies are applied at the periodic refresh of Group Policies and can be used to specify the desktop settings, operating system behavior, user logon and logoff scripts, application settings, security settings, assigned and published applications options and folder redirection options. I cannot connect with Remote Desktop, but I can connect with Services.
All normal services appear to be running OK. I'm wondering if it's looking for, or dependent on one of our other recently decommissioned servers has we have recently decommissioned a PDC and it's likely this is the first time this machine has rebooted since decommissioning the old PDC.
Where would I start with trying to diagnose this problem? Please be aware I'm not a sysadmin - I'm a web developer, so avoid funky acronyms if possible ;. Once the server is booted log in with either local credentials or cached domain credentials if there are any and edit the network configuration removing reference to any resources that are unavailable.
