Login Failed to add shared printer in win7

An error occurred while logging on to Windows 7 with a shared printer. A win2003 operating system was reinstalled in the last two days !, A local HP M1136 printer is shared above! A strange problem occurs. After I set up a shared printer on win2003, some of my colleagues in the company can log on to and use the shared printer through \ 192.168.1.149, however, my own win7 system uses \ 192.168.1.149 to log on to the logon interface, but the login is unsuccessful !!! The prompt is as depressing as it can be accessed by others, so it must be my computer !! After a long time of searching, I finally found a solution! Unable to Access LAN printer under Win7 (Login Failed: Unknown user name or Password error) solution! I have been searching for a long time. It turned out to be simple: Enter gpedit. choose "Local Computer Policy"> "Computer Configuration"> "windows Settings"> "Security Settings"> "Local Policy"> "Security Options"> "Network Security": LAN Manager Authentication Level. the default value is "not defined" and changed to "Send only NTLM responses! In addition, if you cannot access all the shares. Open the "TCP/IP NetBIOS Helper" service.
