Hello,I hope this is the correct forum for this question.I am trying to get the sample CREDSSP code to run (on a vista platform) and have not been able to sucessfully get it to run. The code is from : http://msdn.microsoft.com/en-us/library/cc540483.aspx I did the following: 1) Created a certificated usigng the selfssl utility (it had an error because I don't have IIS installed, but it seems to have correctly installed a certificate) 2) Changed the group policy to include my machine name and also my user name (wasn't really quite sure what should be set - do you have any more information about this? ) 3)Built the sample code. The sample code runs, reads the certificate, sets up thesecurity handles and then gets through the first exchange (ISC/ASC), the second ISC succeeds, but the second ASC fails with error 0x80090330 which is "SEC_E_DECRYPT_FAILURE". Looking at the protocol spec, it would seem that I've sucessfully gone through the TLSClientHello, TLSServerHello, but the TLSClientKeyExchange is failing on the server side as it tried to decrypt the packet I've looked online and can't seem to find any useful information on why this might be happening. It would seem that there might be a problem with the certificate, but I can't figure out what that might be. So the main issue is how do I go about figuring out what I'm doing wrong to get the sample code to run. Here's the output from the run: Using package: credsspUsing default credentials of userAcquiring client credentialsAcquiring server credentialsCertificate subject name = WIN-PW5HZFYFFM5ISC SuccessASC SuccessISC SuccessAcceptSecurityContext failed: 0x80090330 Can anyone help? Or point me in the right direction for additional documentation or samples? Thanks!
