I need to map a network drive over VPN.
Very simple host network: no Microsoft server, no AD. Just one router and a NAS appliance (simple Linux file server).
When at the office, I can map a drive letter as follows:
net use f: \\192.168.1.3\MyShare /User:MYSELF mypass
However, when try same command over VPN, I receive the response:
System error 1244 has occurred. The operation being requested was not performed because the user has not been authenticated.
Two identical Cisco WRVS4400N VPN routers create the VPN. Router1 in office (192.168.1.1), Router2 in soho (192.168.11.1). VPN works perfectly, no client software required. When at SOHO (behind router2 with an IP address of 192.168.11.100), can successfully ping 192.168.1.3.
Routers have latest firmware.
Over VPN I cannot browse network via Windows Explorer (Win7 Network Neighborhood shows only my PC as opposed to several PCs and the NAS box "NAS01" when in the office).
Over VPN, I cannot connect by entering \\192.168.1.3\MyShare into Windows Explorer's address bar (although I can do that successfully when at the office). Over VPN, I am able to view the NAS administration screens via https://192.168.1.3/admin and I can print to the office TCPIP printer (192.168.1.222) -- both non-routable IPs.
Thanks for the important hints and clues as to where to look for the problem.
Windows 7 Home Premium, which is on my laptop, exhibits this behavior.
A different laptop, installed with Windows7 Professional, works fine.
Is it likely that Win7 Home vs. Win7 Pro is the problem? If so, is there any way to overcome this limitation without upgrading to Pro? (i.e. Registry changes, configuration settings, copy over certain files from Pro to Home, etc.)
