Vista - No access to network shares over VPN from Vista

Dear experts


I have a problem accessing any network shares from "outside the LAN" "Windos Server 2003"-systems with a "Windows Vista"-system:

Detailed description:
I have a LAN behind a ADSL-Router and in this LAN there are
Vista-Vista-WS1: A Windows Vista Business Edition x64 (English)(current patch level)
Vista-WS2: A Windows Vista Business Edition x86 (German)(current patch level)
Vista-WS3: A Windows Vista Business Edition x86 (English)(current patch level) in a Virtual Machine
XP-WS: A Windows XP Professional Edition x86 (English)(current patch level)
Srv-LAN: A Windows Server 2003 R2 x86 (English)(current patch level) in a Virtual Machine
The Windows Server is configured as domain controller, VPN-Server, DNS-Server, File-Server

I have a workplace environment in another site which can be accessed over VPN:
DC-WAN: A Windows Server 2003 R2 x86 (English)(current patch level) as Domain Controller
Exchange-WAN: A Windows Server 2003 R2 x86 (English)(current patch level) as Exchange Server
FS-WAN: A Windows Server 2003 R2 x86 (English)(current patch level) as File Server
VPN-WAN: A Windows Server 2003 R2 x86 (English)(current patch level) as VPN-Server
Web-WAN: A Windows Server 2003 R2 x86 (English)(current patch level) as Web-Server

Vista-WS1, Vista-WS2, Vista-WS3, XP-WS
can successfully connect over VPN with Srv-LAN and can successfully map any share from Srv-LAN
Vista-WS1, Vista-WS2, Vista-WS3, XP-WS can successfully connect over VPN with VPN-WAN
Vista-WS1, Vista-WS2, Vista-WS3, XP-WS can successfully connect with the Exchange Server Exchange-WAN
Vista-WS1, Vista-WS2, Vista-WS3, XP-WS can successfully connect with the Web Server Web-WAN
Vista-WS1, Vista-WS2, Vista-WS3 always fail to map any share from FS-WAN
XP-WS can successfully map any share from FS-WAN


Error messages:
c:\> net use x: \\<fqdn>\share
"System error 1214 has occured. The format of the specified network name is invalid."
c:\> net use x: \\<NetBIOS-Name>\share
"System error 53 has occured. The network path was not found."
c:\> net use x: \\<IP-address>\share
"System error 53 has occured. The network path was not found."


Any ideas?
Thanks for your support in advance!

Dear regards and a happy new year... :-)

First I would like to let you kow that I'm very impressed by how you explain
your problem, very well written and all the interesting information to be
able to help you. Thank you

If you try to map a drive with pure IP \\192.168.1.x etc you get different
message? If you disable the Vista build in firewall does it helps?
If you run netstat you get any time out wait entries?
