Server Message Block (SMB), also known as the Common Internet File System (CIFS), is the filesharing protocol used by default on Windows-based computers. Windows includes an SMBclient (the Client For Microsoft Windows feature installed through the properties of a networkconnection) and an SMB server (the File And Printer Sharing For Microsoft Windows featureinstalled through the properties of a network connection). SMB in versions of Windows priorto Windows Server 2008 and Windows Vista, known as SMB 1.0, was originally designed inthe early 1990s for early Windows-based network operating systems, such as Microsoft LANManager and Windows for Workgroups, and carries with it the limitations of its initial design.
Provides a solution for Access Server Message Block (SMB) sharing. Windows Server 2008 R2 Service Pack 1. On the SMB server that's using TCP port 445. #Enable File And Printer Sharing In Windows 10 Without Using The netsh Command in PowerShell. #It is as simple as enabling the pre-configured rule in Windows Firewall to enable File and Printer Sharing in Windows 10 but using netsh is the old fashion way. NetBios services allow file sharing over networks. When improperly configured, ports 135-139 can expose critical system files or give full file system access (run, delete, copy) to any malicious intruder connected to the network.
Windows Server 2008, Windows Vista, and Windows 7 also support SMB 2.0, a new versionof SMB that has been redesigned for today's networking environments and the needs of thenext generation of file servers. SMB 2.0 has the following enhancements:
- Supports sending multiple SMB commands within the same packet. This reduces thenumber of packets sent between an SMB client and server, a common complaint against SMB 1.0.
- Supports much larger buffer sizes compared to SMB 1.0.
- Increases the restrictive constants within the protocol design to allow for scalability.Examples include an increase in the number of concurrent open file handles on theserver and the number of file shares that a server can have.
- Supports durable handles that can withstand short interruptions in network availability.
- Supports symbolic links.
Computers running Windows Server 2008, Windows Vista, or Windows 7 support bothSMB 1.0 and SMB 2.0. SMB 2.0 can be used only if both the client and server support it,however. Therefore, both the client and the server must be using SMB 2.0 to benefit from theimprovements. Windows Vista and Windows 7 support complete backward compatibility withSMB 1.0 and earlier versions of Windows.
As with other versions of Windows, server-side support for SMB (sharing files and printers)is provided by the Server service, and client-side support (connecting to shared resources) isprovided by the Workstation service. Both services are configured to start automatically, andyou can safely disable either service if you don't require it. The security risks presented byhaving the Server service running are minimized because Windows Firewall will block incomingrequests to the Server service on public networks by default.

Resolution
Windows Firewall (or any other firewall) may block Recover Keys from accessing remotepcc$ share in order to login into remote. To fix it you may disable firewall or configure it properly. In Windows Firewall this can be done quite easy - you need to enable 'File and Printer sharing'. Here are more detailed steps:
- Go to 'Control panel'
- Click on 'Windows Firewall'
- If its state is 'On', navigate to 'Exceptions' tab
- Enable 'File and Printer sharing' like on picture below:
