Does anyone know how to use weak keys with System.Security.Cryptography.DES?

There is a check-up implemented which throws CryptographicException if the
DES key is weak ("Specified key is a known weak key for 'DES' and cannot be
used.").

My problem is that a certain communications standard is initiated with 00 00
00 00 00 00 00 00 as a DES key, thus there are two options: either use some
other implementation of DES, or preferably, there is a way to pass this check
in System.Security.Cryptography.DES.

Any help is appreciated.
