XP : speedup access to network shares

I have seen reports that Windows XP is slow when accessing network shares. I use XP daily on my local home network and a corporate LAN. I haven't noticed the network slowness. But if you do, there are reports that deleting a particular registry key resolved the problem. It certainly works for Windows 2000. You can give it a try in XP. I would backup the key first.

HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace/{D6277990-4C6A-11CF-8D87-00AA0060F5BF}

To backup and delete the key, In the regedt32 registry editor navigate to the NameSpace key :

  • Right click {D6277990-4C6A-11CF-8D87-00AA0060F5BF}
  • Click Export. From the Export Registry File dialog box in the File Name text box :
  • Type the filename of your choice as in restoreshare
  • Click Save
    This saves the file names (in my example), restoreshare.reg to the My Documents folder. Its now safe to delete the key.
  • Right click {D6277990-4C6A-11CF-8D87-00AA0060F5BF}
  • Click Delete
  • Click Yes in the Confirm Key Delete dialog box.

If your system is unstable or weird after deleting this key, you can restore the key. In Explorer, double-click on your reg file. This will restore the deleted registry key.
