Known issues with this security update
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.  You do not have to install this update on Microsoft Windows 2000 Professional-based computers. However, you should install this update on all the Windows servers that are listed in the &quot;Applies to&quot; section, whether the server is a domain controller or not. This action helps protect the network if you decide to turn a server into a domain controller. This security update changes the behavior of an earlier released hotfix (906381). Because of the new behavior, only domain administrators and network administrators can renew certificates. Also, an administrator cannot delegate the right to renew certificates. The set of users who can take advantage of this hotfix has been restricted. Customers who want to revert to the old behavior of hotfix 906381 can do so by follow these steps:  Click Start, click Run, type regedit, and then click OK. Locate and then click the following registry subkey:

</li> On the Edit menu, point to New, and then click DWORD Value.</li> Type Enable Skip Server Certificate Renewal Authentication for the name of the DWORD, and then press ENTER.</li> Right-click Enable Skip Server Certificate Renewal Authentication, and then click Modify.</li> In the Value data box, type 1, and then click OK.</li> Exit Registry Editor.</li></ol> </li></ul>
