|Message:||NSPI Proxy cannot contact any Global Catalog that supports the NSPI Service.New clients will be refused until a Global Catalog is available.After a Domain Controller is promoted to a Global Catalog, it must be rebooted to support MAPI Clients.|
This event indicates that the Name Service Provider Interface (NSPI) Proxy cannot contact any global catalogs that support the NSPI Service. New clients will be refused until a global catalog is available. A domain controller that was recently promoted to a global catalog may not have been restarted. A global catalog must be restarted in order for the NSPI interface to be available.
Check the general health of the global catalog servers. If you have recently promoted a domain controller to global catalog, remember that it must be rebooted in order to support MAPI clients.
