Recently a few computers in our domain has switched to Win 7 from Win XP. Now after sharing folder shared folder are not visible while accessing that computer from our Win CE device. Windows XP or Win 7 users can browse shared folders but not WinCE device.

Media Streaming, Network discovery, File sharing is Off. Firewall is turn off.

Any ideas what could be the reason ?.

Network discovery and File sharing need to be turned on. Why did you turn the Firewall off? I recommend that you turn it back on and configure it for network access.

Do you share Pictures, Music and Video in your Domain? If not, leave Media Streaming off. If you do, turn it on.

Yes, generally I keep Media streaming off and Firewall on. But for solving this issue was trying some random steps but nothing helped.

The problem is windows 7 shared folder can be seen by other domain computers but not by the win ce devices. However I can access windows 7 drive by \\hostname\D$

Don't know if this works.

On your Win 7 machine, start Regedit and go to HKLM\system\CurrentControlSet\services\NETBT\Parameters. Change UseNewSmb from 1 to 0.

Reboot.

See if it your Win CE devices can connect. If not, then set it back to 1.

^^. I have both WinCE 5.0 and 6.0 devices. And your posted link is about sharing WinCE folder which is a really new thing for me. Definitely Im going to try this.

Well, HKLM\system\CurrentControlSet\services\NETBT\Parameters trick didn't work.

WinCE device is not able to show direct Win 7 computers share. Instead if I access Win 7 shared folder from WinCE like \\hostname\sharename it works. But \\hostname fails to show all shared folder.

I found this post at the MSgroups site. I copied the post and I'll past it in here. If this work for you, credit goes to Stefano at MSgroups.

Solved the problem is the follow:
Vista & Windows 7 uses NTLMv2 authentication level, WinCE 5.0 and WinCE 6.0
doesn't support it NTLMv2, they only support NTLM. So Security settings
need to change on the Vista system that is going to access the PVC device.

WORKAROUNDS
On the Vista/7 system:
1) Open gpedit.msc
2) "Local Computer Policy / Computer Configuration / Windows Settings /
Security Settings / Local Policies /Security Options
3) In the right hand pane locate Network security - LAN Manager
authentication level"
4) Change the value from "Send NTLMv2 response only" to "Send LM and NTLM -
use NTLMv2 session security if negotiated"

OR REGISTER
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa

Create the following DWORD value (if it doesn't exist):

LmCompatibilityLevel

and set it to 2 !!!!:

0 - Clients use LM and NTLM authentication, but they never use NTLMv2
session security. Domain controllers accept LM, NTLM, and NTLMv2
authentication.

1 - Clients use LM and NTLM authentication, and they use NTLMv2 session
security if the server supports it. Domain controllers accept LM, NTLM, and
NTLMv2 authentication.

2 - Clients use only NTLM authentication, and they use NTLMv2 session
security if the server supports it. Domain controller accepts LM, NTLM, and
NTLMv2 authentication.

3 - Clients use only NTLMv2 authentication, and they use NTLMv2 session
security if the server supports it. Domain controllers accept LM, NTLM, and
NTLMv2 authentication.

4 - Clients use only NTLMv2 authentication, and they use NTLMv2 session
security if the server supports it. Domain controller refuses LM
authentication responses, but it accepts NTLM and NTLMv2.

5 - Clients use only NTLMv2 authentication, and they use NTLMv2 session
security if the server supports it. Domain controller refuses LM and NTLM
authentication responses, but it accepts NTLMv2.

^^ I also got this way from some other forum and tried too. But didn't work.

One thing I missed that is: I didn't reboot the machine after I modify this from secpol.msc. Will do that tomorrow and let you people know.
