1.首先确保在iSeriers能打开该folder
Wrklink 'QDLS'
如果出现如下错误，则需要增加user profile到Directory Entries list
CPF9006
User not enrolled in system distribution directory.

WRKDIRE 命令可以验证下该profile有没有权限,没有就用ADDDIRE加上该profile

2.PC端删除之前其它用户打开该folder的网络映射
net use
net use /delete \AS400IPQDLS
3.这个时候可能发现其它OS可以，但win7打不开，报错
you might not have permission to network resource
Local Computer Policy->Computer Configuration->Windows Settings->Security Settings->Local Policies->Security Options
Find the policy:
Network security: LAN Manager authentication level
Change to Send LM & NTLM - use NTLMv2 session security if negotiated
Microsoft network client: Digitally sign communications (always)
If this is enabled, change it to Disabled.
改了上面的配置后重启再试就OK了。
