FIX: More than 1,000 rules in the NRPT causes no rules to be loaded into memory in Windows


View products that this article applies to.

Summary

On a computer that is running Windows 7, Windows Server 2008 R2, Windows 8 or Windows Server 2012, there is a limit of 1,000 rules in the Name Resolution Policy Table (NRPT) that the DNS Client service can use. However, this limit is not enforced when you add a rule. Instead, no rules are loaded into memory when this limit is exceeded.

This fix that is described in this section removes the 1,000-rule limit for the NRPT. Additionally, this fix minimizes the effect on performance of adding rules.
