Yes, but his Windows XP firewall is not protecting your corporate resources.


If I attempt to browse for anything
inside the corporate network, no network resource is found. I can't
\\servername, cannot browse through MyNetworkPlaces, cannot ping.....

Sounds like he has a basic connectivity problem with the VPN.

Forgot to mention that I cannot seem to resolve names/ip addresses of
any resources on the inside. I can ping and resolve the VPN servers,
and DNS servers, but seems that is all.

Check into the VPN setup - something is wrong. Note that if he uses the same
IP subnet at home (e.g., 192.168.0.0, etc) as you do in the office, VPN
won't work. He will need to change his private IP addressing scheme to
something different. I never like to use any of the more standard stuff on
my networks as they are often used by Linksys/Netgear/whatnot .... but at
this point it probably doesn't make any sense to change the business
network, as that'd be a lot more arduous. Again, this presumes I'm on
target.

Thanks

Would the firewall prevent browsing the internal network?

Thanks,

No; the firewall does not block anything *outbound* at all.

Hello,

We run Windows XP/SP2 with a standard image at our company. Our
standard VPN solution is the AT&T VPN Network Client v5.09.

I have a user who connects to the corporate network from home
(wireless at home). He is able to connect and establish the VPN
tunnel successfully. However, he is unable to browse/see/access
resource on the internal corporate network. He can use Outlook
normally when connected. He is also able to user Microsoft
Communicator, Net Meeting and a couple other applications.
However, he cannot access any Intranet sites, servers, shares,
cannot browse the network, nor use other custom & 3rd party apps
that communicate with network resources.

I am wondering if the Windows firewall could be the cause. His
and my machine have a virtually duplicate setup. In my Windows
firewall on the Advanced tab, I have as the first entry "AGN
Virtual Network Adapter" and this entry is checked. On his
computer, he does not have this entry.

I am wondering if this is the reason he cannot access any internal
resources. Any ideas?

Thanks in advance,
Rich

The Windows firewall doesn't block anything outbound, so this is
not the likely culprit. It could be his home network config -
which is difficult to troubleshoot. If this is a laptop, I'd have
him bring it to you for a checkup, and see if it works from
elsewhere.
