SYMPTOMS
The following error may occur in the event log when you attempt to
authenticate with a third party PPP server using MD5 authentication:
Event ID 20066
General named pipe failure occurred in the Point to Point Protocol engine.
Data is 6 Hex.
CAUSE
Code specific to Microsoft CHAP (MD4) is being executed regardless of the
authentication type. This code verifies that password length does not
exceed the 14 character password length allowed in Microsoft networking.
The password length for MD5 authentication may exceed 14 characters.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5. A
fix to this problem is in development, but has not been regression-tested
and may be destabilizing in production environments. Microsoft does not
recommend implementing this fix at this time. Contact Microsoft Product
Support Services for more information on the availability of this fix.
NOTE: Microsoft Windows NT U.S. Service Pack 2 must be installed before you
install this fix. If it is not, RASPHONE will fail.
