Recently to use PsExec remote run win7 program, but this psexec must be able to access the admin share account to work (admin share is \computernamec$ this way of access). Because Win7 is not able to use the admin share by default under Workgroup (the domain administrator who is in the domain can use admin share), you need to change the settings for Windows:
1. Open Network Discovery and file and printer sharing
2. Registry Hklmsoftwaremicrosoftwindowscurrentversionpoliciessystem plus a DWORD type key "Localaccounttokenfilterpolicy", Value is 1:
Then reboot the computer and OK.
If you can not access the admin share, it is necessary to check whether to join the homegroup:
Open Control Panel-> Network and Internet-> homegroup, click HomeGroup and leave homegroup
If you still can't access admin share, you'll have to toss the settings in Group Policy:
2. Navigate to the "local Policies"-> "the Security Options"
Open Network Security:lan Manager authentication level, set to Send LM & Ntlm–use NTLMv2 session security if negotiated
4. Navigate to "Computer Configuration"/windows settings/security settings/local policies/security Settings "
Network Access:allow anonymous Sid/name translation
Network Access:let Everyone permissions apply to anonymous users
6. Disable the following:
Network access:restrict Anonymous access to Named pipes and Shares
Network Access:do not allow anonymous enumeration of SAM accounts
Network Access:do not allow anonymous enumeration of SAM accounts and shares
