Problem with mapping network location - network printer

[Priesteye]

Hello!
I added a printer to my network (hp c5180) via ethernet cable. But problem accords when I try to map a network location (card reader 5in1 or sth like that, is used to read SD, xD, ms cards used in cameras) from which I d like to copy images, files in explorer without extra software from HP. After I installed drivers for printer, it automatically map a network location but when I try to open it or connect to that location I get an error:

"Access code is invalid"
The network path is "\\192.168.1.9\Memory_card"
I copied this link in to my internet browser (in this case its g Chrome) and I was able to connect to the network location:

Its strange because all of XP based computers can easily connect, problem is only with windows 7 based computers.
Somewhere I found that this could be repaired with changing: (below)

1. Open the Administrative Tools in the Control Panel
2. Open the Local Security Policy
3. Select the Security Option under Local Policies
4. Choose Send LM & NTLM responses in Network security: LAN

or in reg:

In Windows 7, we can set the following Registry key “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contr ol\Lsa\LMCompatibilityLevel” to “1”.

But this solutions dont work in my case.

Does somebody know hot to fix this and what is causing it??
