Version:           4.3 (using KDE 4.4.4) 
OS:                Linux

Can not access Windows 7 network shares.
(User name / password dialog pops again as soon as you hit enter / OK)

After changing this Setting in Windows 7 
  1. Enter “gpedit.msc” in the Start Search box.
  2. Open “Computer Configuration”/Windows Settings/Security Settings/Local Policies/Security Settings.
  3. Disabled: Network access: Restrict anonymous access to Named Pipes and Shares

Then this error shows up in the Konqueror and Dolphin:
Unknown error condition in stat: Function not implemented

Reproducible: Always

Steps to Reproduce:
Look in the details

Please check related policies.

1. Enter “gpedit.msc” in the Start Search box.
2. Open “Computer Configuration”/Windows Settings/Security Settings/Local Policies/Security Settings.
3. In the right pane, enable the following policies:

Network access: Allow anonymous SID/name translation
Network access: Let Everyone permissions apply to anonymous users

Also please disable the following policies.

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

Change the following policy:
Network security: LAN Manager authentication level

Change the value to “Send LM & NTLM - use NTLMv2 session security if negotiated”.

If the issue persists, change the Kerberos encryption type.

1. Open gpedit.msc.
2. Find the policy

Windows Settings -> Security Settings -> Local Policies -> Security Options ->Network Security: Configure encryption types allowed for Kerberos

3. Configure the policy. If it is not configured, actually both DES cipher suites are disabled. I suggest that you enable all the suits.

Then please check the result.

This allows you to access all Windows shares (but it is still a bug in Samba / KDE)
