Win7 Add shared printer login failed

A Win2003 operating system has been installed in the last two days!, which shares an HP M1136 local printer!

Strange problems arise, I set up a shared printer on Win2003. Some of the company's colleagues ' computers can log in and use shared printers through 192.168.1.149, but my own Win7 system passes 192.168.1.149 to the landing screen but the landing was unsuccessful!!! Tips are as follows

Very depressed ah, because others can be normal access, so it must be my own computer settings problem!! After a long time to find the solution finally!

Win7 Cannot access LAN printer (Logon failed: unknown username or password error) solution!

Looking for a long time. It turns out to be simple:

Enter Gpedit.msc open Local Computer policy-> Computer Configuration->windows Settings-> security Settings-> Local policy-> security options-> Network security: LAN Manager authentication level.

The default is no definition, and change to send only NTLM responses!

Also, if you cannot access all the shares. Please open the TCP/IP NetBIOS Helper service.
