win 7 不能 拷文件到 xp

具體情況是, 一台新機裝了 (電腦1) Win7 x64  及 XP sp2 雙啟動, 另一台 NAS 的機是運行 XP xp2。
電腦1 運行 win7 時, 讀取 NAS 的文件完全沒問題。
電腦1 運行 win7 時, 可以 對NAS 開新目錄, 可以刪除 NAS 的文件。
電腦1 運行 win7 時, 不能抄大於 數百K 大小的文件往 NAS (XP sp2), 有些時候抄數個 一百mb 文件也是成的, 但只限很小次數, 長期使用肯定不行 。

NAS 的目錄都設了該用戶給讀寫, 全權控制的權利。

電腦1 運行 XP xp2 時, 抄 1Gb文件往 NAS 也沒問題(抄往NAS的同一目錄)。


(電腦 1)  win 7 x64 ,
網絡是工作場所, 不是 Home Group.
電腦1 的工作群組是  WORKGROUP , 全大寫, 與 xp 機相同。
電腦 1 Win7 x64 , 和 NAS XP sp2 使用相同用戶名, 相同 密碼。
電腦 1 Win 7 x64 和 NAS XP sp2 的 ip 都是。
兩部機都把防火牆, 防毒全關閉。

NAS XP sp2
工作群組 是 WORKGROUP
用戶名 和 密碼均和 電腦1 WIN7 相同。
兩部機都把防火牆, 防毒全關閉。


下面網上找到的方法都試了, 無效。

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
and set the following registry key to ’3′:
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServe r\Parameters\Size
After making these changes and restarting, I haven’t seen this issue arise again.




In Windows Vista or Windows 7  it is often seen that Mapped Drive gets disconnected when a data transfer like copy or move action is in progress. The problem occurs because of  Windows Vista’s Auto tuning network feature  So if you are more into copying large files from one computer to another it is recommend to turn this feature off.
To turn Auto Tuning network off:

    Run the command prompt in administrative mode
    pressing ctrl + shift + enter or right click and run as administrator OR right click on command prompt and selecting run as administrator
    To turn auto tuning off type “netsh int tcp set global autotuninglevel = disabled” and if this doesn’t work try netsh interface tcp set global autotuninglevel=high
    To turn it on again : “netsh int tcp set global autotuninglevel = normal”
Turn Auto Tuning Off in Windows
Once you get an Ok message, reboot your computer for settings to take place. To make sure Auto Tuning setting was changed, run the command netsh interface tcp show global, this will display all the major config of TCP and you will see Recieve Windows Auto Tuning Level as disabled if you set it so.





That said, the following has helped a number of people:

        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
        Add or modify IRPStackSize to the maximum setting of decimal 50
*Add 0xC

        see http://support.microsoft.com/kb/106167 for details
        HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters
        Size - change to decimal 3
*Change from 1 to 3

        http://technet.microsoft.com/en-us/libr ... 10%29.aspx
        HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
        LargeSystemCache - change to decimal 1
*Change from 0 to 1





sc config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc config mrxsmb20 start= disabled



Netsh interface IPv4 set interface "Local Area Connection" WeakHostSend=enabled
Ok.
Netsh interface IPv4 set interface "Local Area Connection" WeakHostReceive=enabled
Ok.



To disable certain IPv6 components, follow these steps:
    Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list.
    In the User Account Control dialog box, click Continue.
    In Registry Editor, locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\
    Double-click DisabledComponents to change the DisabledComponents entry.

    Note If the DisabledComponents entry is unavailable, you must create it. To do this, follow these steps:
        In the Edit menu, point to New, and then click DWORD (32-bit) Value.
        Type DisabledComponents, and then press Enter.
        Double-click DisabledComponents.
    Type any of the following values in the Value data field to configure the IPv6 protocol to the intended state, and then click OK:
        Type 0 to re-enable all IPv6 components (Windows default setting).
        Type 0xff to disable all IPv6 components except the IPv6 loopback interface. This value also configures Windows to prefer using IPv4 over IPv6 by changing entries in the prefix policy table. For more information, see Source and destination address selection.
        Type 0x20 to prefer IPv4 over IPv6 by changing entries in the prefix policy table.
        Type 0x10 to disable IPv6 on all nontunnel interfaces (both LAN and Point-to-Point Protocol [PPP] interfaces).
        Type 0x01 to disable IPv6 on all tunnel interfaces. These include Intra-Site Automatic Tunnel Addressing Protocol (ISATAP), 6to4, and Teredo.
        Type 0x11 to disable all IPv6 interfaces except for the IPv6 loopback interface.
