I'm trying to share my P:\ drive on a Windows 7 (Pro) PC with other PCs (WinXP) on my network.
I shared it and set permissions to give Everyone Full Control.
Symptoms
-
Computer XP(different computer on the network) can access \win7\users\ public (and copy files to it and edit files in that folder) but not the \win7\p:\
-
Folders I've shared on the Windows 7 PC are visible to the XP computers but just not accessible . From the other WinXP PCs on the LAN accessing the Win7 PC, I get "win7\p not accessible. You might not have permission to use the network resource. " "Access Denied".
Edit: I've to Advanced Sharing options set to have the following enabled:
- Network Discovery
- File and Printer sharing
- Sharing so anyone can read/write files to public folders.
- 128 bit encryption (perhaps this is an issue? Perhaps it should be set to 40 bit encryption?)
- Allow Windows to manage homegroup.
- XP machines are set to not use Simple File Sharing.
Other Things I've Tried
- Confirmed all computers are in the MSHOME workgroup.
- Turned off the Windows 7 Firewall, briefly. Problem persisted.
- Tried the Windows 7 Network Troubleshooter. Just led me around in a circle saying "found problem…need more information". The links from there led back to the Network Troubleshooter.
- tried disabling the Firewall on the Windows XP machine. No joy.
- Verified the XP machines are both on Win XP SP3 and both have "download updates" turned on.
- Installed IE8 on the XP machine1. (Previously it had IE 6). Still no joy.
Any ideas?
Best Answer
Try this on the Windows 7 machine:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
and create or modify the value of LocalAccountTokenFilterPolicy (32-bit dword) to 1, so the remote logon token will not be filtered (see here).
