You open the Group Policy Management Editor window to create some Name Resolution Policy Table (NRPT) policy entries on a computer that is running Windows 7 or Windows Server 2008.
You add or edit a NRPT policy and then click the Apply button to apply the setting.
In this scenario, the Group Policy Management Editor Microsoft Management Console (MMC) snap-in window may crash.
The name field of these NRPT policy settings should be saved as a MULTI_SZ data type in the registry. This data type requires two NULL characters as the terminating null characters. However, the Group Policy Management Editor does not add the two NULL characters when Group Policy Management Editor saves the settings. Therefore, the Group Policy Management Editor window crashes when it tries to save the settings.

Windows 7 and Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
