I added Firefox. I updated a "bunch" of other stuff that my daughter hadn't bothered to update. I updated the bios through Dell. I cannot backup her Vista Ultimate SP2 laptop! I did look at the event logs and I do see event , , I believe and I can't really figure out what is going on. I really don't want to begin to look at every nut and bolt in order to solve this problem.
I am hoping someone can shed some light on this situation. I have several other laptops and desktops all XP Pro that are running great. I recently upgraded the HD in two of my laptops and the whs restored flawlessly to the new drives. Any suggestions for the Vista laptop would be appreciated! Post subject: Re: Backup slow and eventually fails vista ultimate. I have several Vista Ultimate machines that back up no problem. I would uninstall the WHS connector and then reinstall it after a reboot.
That is what I would try first. Posted: Wed Aug 26, am. Loren Did a reinstall - reboot client - reboot server - no luck thanks though Russ. Those numeric error numbers are not particularly helpful to most of us. Could you post a copy of the pertinent portions of the log so we could see the complete text? Cypher suites are configured for the Schannel security support provider in prioritized order and certain suites are only available on specific operating system versions. This error message could occur when the client application, such as a web browser is using a version of the SSL protocol not supported on the server, causing the connection cannot be made.
In response to the client hello message, the server requested SSL client authentication. Because the client did not possess a suitable certificate, the connection process will proceed by attempting an anonymous connection. In this scenario, which has security vulnerabilities, both client and server do not get authenticated and no credentials are needed to establish an SSL connection. The client certificate contains, among other information, what cipher suite it supports — and by extension, which protocol it supports.
Certificates are issued with a planned lifetime and explicit expiration date. A certificate may be issued for one minute, thirty years or even more. Once issued, a certificate becomes valid once its validity time has been reached, and it is considered valid until its expiration date. However, various circumstances might cause a certificate to become invalid prior to the expiration of the validity period.
Such circumstances include change of name, change of association between subject and CA for example, when an employee terminates employment with an organization , and compromise or suspected compromise of the corresponding private key. This issue occurs because LDAP caches the certificate on the server. Although the certificate has expired and the server receives a new certificate from a CA, the server uses the cached certificate, which is expired. You must restart the server before the server uses the new certificate.
A CA is a mutually-trusted third party that confirms the identity of a certificate requestor usually a user or computer , and then issues the requestor a certificate. CAs also renew and revoke certificates as necessary. If the issuing CA is trusted, the client will verify that the certificate is authentic and has not been tampered with.
When a server application requires client authentication, Schannel automatically attempts to map the certificate supplied by the client to a user account. The handshake allows the server to authenticate itself to the client by using public-key techniques, and then allows the client and the server to cooperate in the creation of symmetric keys used for rapid encryption, decryption, and tamper detection during the session that follows.
Optionally, the handshake also allows the client to authenticate itself to the server. The Schannel provider creates the list of trusted certification authorities by searching the Trusted Root Certification Authorities store on the local computer.
When Schannel detects a certificate that was issued by an untrusted certification authority, this error is logged. All certificates in a certificate chain may be processed to verify that none of the certificates is revoked. Certificate chain validation is of course optional from an application standpoint and may not be enforced by CryptoAPI. The Windows operating system by default checks certificate revocation status via certificate revocation lists, as the CRL processing engine is the native revocation provider included with CryptoAPI.
When this functionality has been invoked each certificate in the certificate chain is checked against the compared specified in the CRL published in the CRL Distribution Point CDP extension in the certificate.
If the certificate is found to be included in the CRL, the certificate is then considered revoked. The server certificate contains the name of the server, which must match that which is contained in one of the certificates on the client computer.
If the certificate name differs between the fully qualified domain name FQDN and the local server name, the connection will fail.
The server sends a list of trusted certification authorities to the client if the following conditions are true:. This list of trusted certification authorities represents the authorities from which the server can accept a client certificate.
To be authenticated by the server, the client must have a certificate that is present in the chain of certificates to a root certificate from the server's list. Every certificate that is trusted for client authentication purposes is added to the list, which is restricted by size limits.
If the size of this list exceeds the maximum in bytes, the Schannel logs Warning event ID Then, Schannel truncates the list of trusted root certificates and sends this truncated list to the client computer. When the client computer receives the truncated list of trusted root certificates, the client computer might not have a certificate that exists in the chain of a trusted certificate issuer.
The TLS alert sub-protocol uses messages to indicate a change in status or an error condition to the peer. There are a wide variety of alerts to notify the peer of both normal and error conditions. Alerts are commonly sent when the connection is closed, a message which is not valid is received, a message cannot be decrypted, or the user cancels the operation.
This alert message indicates this computer received a TLS or SSL fatal alert message from the server it was communicating or negotiating with.
The error indicates a state in the communication process, not necessarily a problem with the application. However, the cause could be how the application, such as a web browser, handled the communication. The two alert types are warning and fatal.
With a fatal error, the connection is closed immediately. This event indicates that this computer the computer that logs this event has detected an error condition and generated a fatal alert to notify the other party about it. Alerts are commonly sent when the connection is closed, an invalid message is received, a message cannot be decrypted, or the user cancels the operation.
Step 5 : After opening the key, set its Value data to 1 and choose Hexadecimal. Then, click OK to save changes. If you have updated your Windows recently, try uninstalling the update. Alternatively, you can also perform a system restore to bring your Windows back to an earlier date. After removing the problematic update, you need to hide it to prevent your Windows from reinstalling it automatically.
Then, restart your computer to see if the problem disappears. Some system files are responsible for TSL encryption and you might also receive the Schannel error fatal alert 42 if these files get corrupted. To fix the corrupted system files, you can use the Windows built-in utility: System File Checker by following the steps below:.
After the verification process is completed, restart your device and check if the error is fixed. Disabling TLS may leave your system vulnerable to certain browser hijackers, but it could help you resolve the Schannel error temporarily. If the above methods fail to fix the issue, you can try this solution.
