The error code translates to NTE_PROV_TYPE_NO_MATCH, and it's no doubt
returned from CryptAcquireContext. I've never seen this error code before--I
thought I'd seen them all! In any case, it sounds like the KEY_PROV_INFO
property on the server certificate is set incorrectly. Perhaps you changed
the CSP type without changing the CSP name to match?

As to the original problem, the NTE_BAD_FLAGS error code also indicates a
problem with the KEY_PROV_INFO property. Since this is a machine key the
flags value should be set to 0x20 (CRYPT_MACHINE_KEYSET). No other flags are
allowed.

Regards,
John

In continiuation with above message , I read in a link

 when performing server-side SSL handshakes, all server private keys need to
be stored in CSPs of type PROV_RSA_SCHANNEL .But in that case also
AcquireCredentialsHandle returns SEC_E_UNKNOWN_CREDENTIALS.In the event
viewer error code :0x8009001b

Pls consider my problem.Thanx in Advance
