When your Windows 2000 Server, that has Service Pack 2 applied, starts, the Netlogon service does not start and the
subject events may be logged. Additionally, if you open Internet Explorer and press Help / About Internet Explorer, you
may notice that your cipher strength is 0-bit.
When you applied Service Pack 2, setup automatically converted your computer to 128-bit encryption, and copied an
updated version to Rsaenh.dll your %SystemRoot%\System32 folder. The subject error is the result of having
a missing, damaged, or older version of Rsaenh.dll. The correct version (for SP2) of Rsaenh.dll is
5.00.2195.2228 and the file should contain 133,904 bytes.
To resolve the problem:
1. Check the version and size of SystemRoot%\system32\dllcache\rsaenh.dll. If this is correct, copy it to a floppy and
go to step 4.
2. If you have the network Service Pack 2 Download, expand it to a temporary folder (W2KSP2_2.146.4_en.exe /x). At a
CMD prompt, type Expand <Drive:>\Folder\i386\new\rsaenh.dl_ A:\rsaenh.dll. Go to
step 4.
3. If you do NOT have the correct version, click here to download rsaenh.dll to
a floppy.
4. Start the Recovery Console.
5. Type cd System32 and press Enter.
6. Insert the floppy and type copy A:\rsaenh.dll rsaenh.dll and press Enter.
7. Type cd dllcache and press Enter.
8. Type copy A:\rsaenh.dll rsaenh.dll and press Enter.
9. Remove the floppy and type exit to restart your server.
