We are rolling out Windows 7 workstations. Users are having issues accessing folders that they used to be able to. We checked the permission carefully at the folder and share level and all looks right. Any suggestions as to how to fix. The server we are accessing is Windows server 2003.

There are several procedures that may help: 1. Force W 7 to use SMB 1 instead of SMB 2: sc config lanmanworkstation depend= bowser/mrxsmb10/nsi sc config mrxsmb20 start= disabled (Return path sc config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi sc config mrxsmb20 start= auto ) 2. Autotuning netsh int tcp set global autotuninglevel=disabled 3. Heuristics netsh int tcp set heuristics disabled 4. Is this workgroup or Active Directory? 5. It is helpful to analyze network traffic (eg. Wireshark) Regards Milos

Milos, So I assume we would run this on the fileserver sharing up the files/folders? This is AD not workgroup. One note of interest, if we provide the user Domain Admin privledges (temporaily) the problem goes away Thanks, Chris ...

Hi Chris, Please check if this KB You cannot access shared files or shared printers in Windows 7 or in Windows Server 2008 R2 helps. If not, please try the following: 1. Temporarily disable the firewall and anti-virus program 2. What about to access the share folder by \\XXX.XXX.XXX.XXX<IP Address>and see how it works? 3. Test the issue in Clean Boot. Hope this helps. Vincent Wang TechNet Community Support
