Windows 7 and Time Capsule attached disk - folder copying problems

Question

We have a Time Capsule in a LAN with a USB disk attached to the USB port. The USB disk is available and writable by all computers (Mac OS X, Ubuntu, and Windows 7).
On the Windows 7 PC, the Airport utility is installed along with Bonjour. The drives appear in Windows explorer and can be navigated.
On the Windows 7 PC, when trying to copy folders across to the disk attached to the Time Capsule it often fails saying the disk is no longer available. The disk attached to the Time Capsule is fully functional and so it looks like some config issue within Windows 7!
Could someone please advise what I need to change within Windows 7 to make the use of the disk attached to the Time Capsule more stable?
Thanks for any help!

There are a number of posts related to copying issues between Windows 7 and AirPort Disks. Two potential solutions being forwarded are: 1) Changing the LAN Manager authentication level, and/or 2) Disabling the Windows Search feature.
To change the LAN Manager authentication level:
o From the Vista desktop, click Start
o Search for: security
o Click 'Local Security Policy'
o Goto Local Policies > Security Options
o Under Policy, double-click 'Network security: LAN Manager authentication level'
o Change level to: Send LM & NTLM responses
o Under Policy, double-click 'Network security: Minimum session security for NTLM SSP based (including RPC) clients'
o De-select 'Require 128-bit encryption'
o Click OK
To disable Windows Search:
o Start > Control Panel > Programs > Programs & Features
o On the right-hand side, click "Turn Windows features on/off"
o Scroll down, and de-select "Windows Search".
o Press OK, close all windows and restart.
