Printer registration error
Hi all, the universal print connector fails to register a printer every time. In found this error in the event log: Exception when sending registration request for Drucker Zentrale System.N...
bandelj The error appears to be related to TLS 1.2. The Connector uses that as our Universal Print service requires it. It might be that the TLS 1.2 needs to be configured on this Windows Server. A few things to check, and then instructions on how to enable/verify this:
1. Is the operating system updated (as far as security patches go)?
2. Have you explicitly disabled TLS 1.2 on the server? If no, below might help
To enable TLS 1.2:
- Set the following registry keys:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319] "SchUseStrongCrypto"=dword:00000001 - Restart the server.
Thank you keeron. The VM we used was very old and had some problems. Just changing the settings you named didn't help. We created a new VM and now everything is up and running
