Hi Everyone, I am experiencing a problem mapping drives via DFS in Windows 7. I can UNC to the DFS root (\\domain.local) and access the share I need ("shared") with no issues. I can also UNC the full path (\\domain.local\shared) with no issues. DFS config is fine, as both UNC and mapped drive work in WinXP and Vista. However if I try to map the link to a drive letter in Windows 7, I get prompted for a username and password. Once I enter the credentials, I am prompted again with an "Access Denied" error at the bottom (see screenshot below; domain and ID blanked out for security purposes). Short description = I can UNC a DFS link but cannot map the link to a drive letter. Any ideas or input? Thanks!

Hi, This problem occurs if the following conditions are true: 1. You do not give the Full Control shared permission to the Everyone group.32 You give the Full Control shared permission to the Administrators group. If you would not like to change the permission settings of the UNC drive, please try the following steps. 1. Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list. 2. If you are prompted for an administrator password, type your password. Or, if you are prompted for confirmation, click Continue.3. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System If the LocalAccountTokenFilterPolicy registry entry does not exist, follow these steps: 1). On the Edit menu, point to New, and then click DWORD Value.2). Type LocalAccountTokenFilterPolicy, and then press ENTER. 4. Right-click LocalAccountTokenFilterPolicy, and then click Modify.5. In the Value data box, type 1, and then click OK.6. Exit Registry Editor.Arthur Xie - MSFT

I just installed the Windows 7 RC. Now I can map the DFS shares to drive letters. But, everytime the client computer reboots the drive letter shows a red X and says it can not connect to a network drive. This causes all kinds of problems for our software that needs to run when the user logs in. If after bootup the client goes directly to the UNC path of the DFS share then the mapped drive starts working. But this is not workable for us. How do we get the mapped DFS ahres to work on bootup with Windows 7? Is DFS going to be supported with Windows 7. I have already tried the regedit listed above. This does not solve the problem of the disconnected network drives.
