Event ID 1519 on Domain Controller

You may receive the following error message on a domain controller: This error message indicates that the server is running out of version storage.

No time limit is enforced on Name Service Provider Interface (NSPI), so a single client (or very small number of clients) performing an expensive and extended search can run a domain controller out of version store and resources. For example, if a user is performing a Messaging Application Programming Interface (MAPI) name resolution on the letter "m," the query finds every user whose company starts with the letter m (as in Microsoft). The search times out after a couple minutes, but one or two clients performing this search is enough to starve a system with a high update load of version store, and lead to this behavior.
