11.21.3 Discussion

You can bypass the part of the DC Locator process that determines a client's site by hard-coding it in the Registry. This is generally not recommended and should primarily be used as a troubleshooting tool. If a client is experiencing authentication delays due to a misconfigured site or subnet object, you can hard-code its site so it temporarily points to a more optimal location (and domain controller).
