Missing Sharepoint Central Administration application


Somehow our friendly Central Administration web application was deleted or collapsed irreversably. Than how could you reprovision it ? sure you can rerun Configuration Wizard but it will take time and makes lots of change. Thanks to Microsoft that we have console executable named psconfig.exe in DRIVE:\Program Files\Common Files\Microsoft Shared\Web Server Extentions\14\BIN\psconfig.exe

To provision CA use that command:

psconfig.exe -cmd adminvs -port 9999 -provision -windowsauthprovider onlyusentlm

Manages the SharePoint Central Administration Web application on the local computer. Takes the following optional parameters:

[-provision]

Provisions the SharePoint Central Administration Web application on this server. Provisioning creates a new SharePoint Central Administration Web application and an application pool running under the server farm administrator’s account.

[-unprovision]

Unprovisions the SharePoint Central Administration Web application from this server. Unprovisioning removes the SharePoint Central Administration Web application and its application pool.

[-port <port number>]

The SharePoint Central Administration Web application port is a global setting to the server farm. When changing the port, a SharePoint Timer service job is dispatched to synchronize the port for all SharePoint Central Administration Web applications in the server farm. If a port is not specified, the port that is used for existing SharePoint Central Administration Web applications in the server farm is used. If a SharePoint Central Administration web Application has not been provisioned in the server farm, the default port selected will be random if a port is not specified.

[-windowsauthprovider <enablekerberos | onlyusentlm>]

The SharePoint Central Administration Web application authentication provider is a global setting to the server farm. When you change the authentication provider, a SharePoint Timer service job will be dispatched to synchronize the provider on all SharePoint Central Administration Web Applications in the server farm. If onlyusentlm is specified, NTLM will be the exclusive authentication provider for all SharePoint Central Administration Web applications. All other authentication providers are disabled and NTLM will be the only authentication provider allowed. If enablekerberos is specified, Kerberos authentication is enabled for all SharePoint Central Administration Web applications. If an authentication provider is not specified, the provider that is used for existing SharePoint Central Administration Web applications in the server farm will be used. If a SharePoint Central Administration Web application has not been provisioned in the server farm, the Kerberos authentication provider will be enabled if an authentication provider is not specified.

    Thank you very much for your article, but I found it wrong. It should be “adminvs” instead of “adminsv”. But I like this article very much. 🙂
