Vista webstation - Error message in FIPS-compliant systems first time you enter the logging screen and red X instead of values in TGML pictures

Issue

  • Error message in FIPS-compliant systems when you use Windows Communication Foundation to serialize generic types: “This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms”
  • Red X instead of values

Environment

  • Vista
  • Webstation

Cause

System cryptography: Use FIPS compliant algorithms for encryption, hashing and signing

This security setting determines if the Transport Layer Security/Secure Sockets Layer (TL/SS) Security Provider supports only the TLS_RSA_WITH_3DES_EDE_CBC_SHA cipher suite. In effect, this means that the provider only supports the Transport Layer Security (TLS) protocol as a client and as a server (if applicable). It uses only the Triple DES encryption algorithm for the TLS traffic encryption, only the Rivest, Shamir, and Adleman (RSA) public key algorithm for the TLS key exchange and authentication, and only the Secure Hashing Algorithm 1 (SHA-1) for the TLS hashing requirements.

For Encrypting File System Service (EFS), it supports only the Triple Data Encryption Standard (DES) encryption algorithm for encrypting file data supported by the NTFS file system. By default, EFS uses the Advanced Encryption Standard (AES) algorithm with a 256-bit key in the Windows Server 2003 family and DESX algorithm in Windows XP for encrypting file data. For information about EFS, see Encrypting File System.

Resolution

Go to Local Security Settings
Security Settings > Local Policies > Security Options
System cryptography: Use FIPS compliant algorithms for encryption, hashing and signing = Make sure its disabled

to get to local security you can go to

1. go to start
2. Go to run
3. enter secpol.msc
4. press enter
