Does Windows 2003 support TLS 1.1 and 1.2?

Does windows 2003 support TLS 1.1 and 1.2. The server need to consume the service hosted on other server, using https with TLS 1.1 and 1.2 certificate.

Solution 1:

It is not supported natively. Support for TLS 1.1 and 1.2 was added to Windows Server 2008 R2.

See How to restrict the use of certain cryptographic algorithms and protocols in Schannel.dll.

Neither IIS provided with Windows 2003 nor Internet Explorer versions 7 and 8 (executable on Windows 2003) support TLS 1.1/TLS 1.2.

If the application uses the library provided by operating system (schannel.dll), then Windows 2003 supports only: SSL 2.0, SSL 3.0 and TLS 1.0.

However if the application used/implemented another library, it might support the versions in question (for example Chrome and Firefox browsers support TLS 1.1 and 1.2 when running on older Windows systems as well).
