RDCMan是微软出品的一个十分方便的远程桌面连接工具。但是当连接到 Hyper-V 主机的时候有时会出现以下错误“Unknown disconnection reason 3848”如图所示

出错原因:

the Credential Security Service Provider (CredSSP) policy on the Hyper-V host is not enabled to authenticate user credentials from a remote location.

解决方法:

启动PowerShell,执行以下命令:

New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults\AllowDefaultCredentials -Name Hyper-V -PropertyType String -Value "Microsoft Virtual Console Service/*" -Force
New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults\AllowDefaultCredentialsDomain -Name Hyper-V -PropertyType String -Value "Microsoft Virtual Console Service/*" -Force
New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults\AllowFreshCredentials -Name Hyper-V -PropertyType String -Value "Microsoft Virtual Console Service/*" -Force
New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults\AllowFreshCredentialsDomain -Name Hyper-V -PropertyType String -Value "Microsoft Virtual Console Service/*" -Force
