Why am I receiving event ID errors 5737 and 7023 on my Windows 2000 Server Service Pack 2 (SP2) system?

A. Event ID 5737 is an unspecified Netlogon service error, and event ID 7023 is a Kerberos Key Distribution service error. Both errors prevent the concerned services from starting and are the result of a corrupt or missing rsaenh.dll file, which is the Microsoft Enhanced Cryptographic Provider. Win2K SP2 automatically upgrades the system to 128-bit encryption. In so doing, the service pack attempts to install the rsaenh.dll file. To resolve the problem, copy the rsaenh.dll file from another server or from the extracted service pack.
