Hi, Thanks for the post! Enter your Windows 7 into Safe Mode with networking. Then access the shared folder. Will the explorer crash? If not, try a Clean Boot to find which could casue the issue. Meanwhile, modify the security policy settings like following: 1. Click Start, input secpol.msc, run as administrator. 2. Navigate to Security Settings - Local Policies - Security Options 3. In the right panel, find "Network Security:LAN Manager Authentication Level", double-click it. Change the setting to:"Send LM&NTLM - use NTLMv2 session if negotiated". 4. Find "Network Security: Minimum session security for NTLM SSP based (including secure RPC) clients", uncheck the "Require 128-bit encryption" box. Then click OK. If the crash exist in Safe Mode with Networking. Try to enable the user-mode dump file to troubleshoot this issue. 1. Click Start, input regedit in the search box, press Enter 2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting 3. Right-click Windows Error Reporting, choose New Key, name it LocalDumps. 4. Right-click LocalDumps, choose New Key, name it Explorer.exe 5. Click Explorer.exe, on the right pane, right-click choose New Expandable String Value, name it Dump Folder. 6. Double-click Dump Folder, set the value date: C:\LocalDumps If the Windows Explorer crash again, upload this C:\LocalDumps folder to your SkyDrive in a public folder and give us a link here. Then I'll check if can find the cause. In addition, please ask your office-related question in Office Forum. Thanks for your cooperation and cooperation!
