SYMPTOMS
If you install Microsoft Windows NT Service Pack 3 when Microsoft Enhanced Cryptographic Service Provider (CSP) and Microsoft CyrptoAPI versions 1.0 and 2.0 are installed on your computer, entries for the digital signature may be damaged or missing from the registry. If the CSP is not properly registered, it does not load and no error message is displayed.

The Advapi32.dll file, included with Windows NT Service Pack 3, may generate either of the following error values:


 * 0x8009001A (NTE_KEYSET_ENTRY_BAD)
 * 0x80090006 (NTE_BAD_SIGNATURE)



RESOLUTION
A fix to this problem is available that makes the necessary changes to the registry. To obtain the fix, download the appropriate self-extracting executable file:

These files can be obtained from the following Microsoft FTP site:

ftp://ftp.microsoft.com/softlib/mslfiles

Each self-extracting executable file contains the following files:


 * Readme.txt
 * Rsaenh.reg

The Readme.txt file contains instructions about how to merge the required keys into your registry, and the Rsaenh.reg file contains the registry key values needed to resolve the problem.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows NT Service Pack 3.
