TLS Schannel Errors

Had an issue the other day and it took me awhile to find out what the TLS Schannel error codes meant.

The exact error message I was receiving was:

After doing some "googling" I was able to find a nice list of the Schannel error message:

Error Code	Description
0	CLOSE NOTIFY
10	UNEXPECTED MESSAGE
20	BAD RECORD MAC
21	DECRYPTION FAILED
22	RECORD OVERFLOW
30	DECOMPRESSION FAIL
40	HANDSHAKE FAILURE
42	BAD CERTIFICATE
43	UNSUPPORTED CERT
44	CERTIFICATE REVOKED
45	CERTIFICATE EXPIRED
46	CERTIFICATE UNKNOWN
47	ILLEGAL PARAMETER
48	UNKNOWN CA
49	ACCESS DENIED
50	DECODE ERROR
51	DECRYPT ERROR
60	EXPORT RESTRICTION
70	PROTOCOL VERSION
71	INSUFFIENT SECURITY
80	INTERNAL ERROR
90	USER CANCELED
100	NO RENEGOTIATION
110	UNSUPPORTED EXT

From the error message i was receiving in the Windows System Event Viewer we can see that the error code was/is "42" which relates to a "BAD CERTIFICATE"

From here I re-generated the certificate on the Lync gateway, and restarted the Lync SBA that was associated with the trunk and the Schannel error and related mediation Server errors cleared.
