Win7 add shared printer login failed

I reinstalled a win2003 operating system in the last two days!, I shared a HP M1136 local printer!
The strange problem appeared. After setting up the shared printer on win2003, some of my company's colleagues' computers can pass 192.168. 1.149 Normal login and use shared printer, but my own win7 system through 192.168.1.149 to the login interface but the login is not successful!!! The prompt is as follows

It is very depressed, because others can access normally, so it is definitely My own computer settings!! After a long search, I finally found a solution!
Unable to access the LAN printer under Win7 (login failure: unknown username or password error) Solution!
Looked for a long time . It turns out to be simple:
Enter gpedit.msc Open Local Computer Policy -> Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> Network Security: LAN Manager Identity Verification level.
The default is "no definition", change to "only send NTLM responses!
Also, if all shares are not accessible. Please open the "TCP/IP NetBIOS Helper" service.
