Jeg har læst mig til der kan være en fejl i nogle versioner af windows 7 der gør shareing næsten umuligt, men med denne her fremgangsmåde blev mine problemer løst.
Here's another Windows7 'fix' should you not want to enable the Guest account:
1. Open a command prompt (cmd.exe), type mmc and <enter>
2. Windows7 will prompt you for elevated security access for MMC - allow this
3. When MMC loads, under "File", select "Add or Remove Snap-In"
4. From the list of Snap-Ins, highlight "Group Policy Object Editor", select "Add"
5. A dialogue box will appear, select "Local Computer"
6. Hit 'OK'. You now should be back at the MMC panel
7. In the explorer window, expand "Console Root" > "Local Computer Policy" > "Computer Configuration" > "Windows Settings" > "Security Settings" > "Local Policies" - Click on "Security Options" under "Local Policies"
8. Under "Security Options", make the following changes:
Network access: Allow anonymous SID/name translation: Change to "Enable"
Network access: Do not allow anonymous enumeration of SAM accounts - Change to "Disabled"
Network access: Do not allow anonymous enumeration of SAM accounts and shares - Change to "Disabled"
Network access: Let Everyone permissions apply to anonymous users - Change to "Enable"
Network access: Restrict anonymous access to Named Pipes and Shares - Change to "Disabled"
Network access: Shares that can be accessed anonymously - Added your root share name here
Network access: LAN Manager authentication level - Change to LM & NTLM, send NTLMv2 if negotiated
9. Close MMC
10. Reboot the PC
