In Windows 7 I was able to map a drive to all my other network shares, but not the ones on the SAN.HERE ishow I fixed it (hope it works for you):1. Click start2. Type: regedit3. Press enter4. In the left pane, expand these folders: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\5. In the left pane, click on the folder named: Lsa6. In the right pane, double-click "LmCompatibilityLevel" (If it doesnt exist, right click andcreate it new as a DWORD value)7.For the Value putthe number 1 and press enter8. Restart your computer
