Does that make sense?

I am using a Dell M90 laptop running XP, and using Comcast from home.
I am connected to the comcast modem directly. I am not going though
any sort of wireless router/NAT device.

The VPN was configured for me in Arlington, Virgina. I am in Denver,
Colorado.

When I tried the VPN from my office in Arlington, it worked. When I
tried from my home in Denver, the VPN seemed to connect, I did not get
any error messages, but it wouldn't work. I can not connect to any of
the secure sites. I just get a "Page not found" error.

It would be difficult for me to get the laptop back to Arlington.
Although, that is what the tech support people want. Comcast will not
give me any help.

Is there anything I can try?

Are you able to surf and use the internet before VPN (may have to
disable a proxy)? Are you getting connected to the vpn or aren't
you? Did you get prompted for a password? Did it get accepted and
connect you, or did you get an error message? What does your
'ipconfig' look like once you 'connect'? Do you have a vpn IP and a
physical IP? Can you ping the default gateway for each? If not, what
are the results? What is your company's network/security engineer
saying? Does he see you connecting? If/when connected to the vpn,
can you do anything on the remote network (ie surf, email, chat, etc)?

Yes. And I am not using a proxy.

> Are you getting connected to the vpn or aren't

I seem to connect, I don't get any errors. But, I can not reach
anything after I am "connected"

> Did you get prompted for a password?

Yes.

My password is accepted and I do not get an error message.

> What does your 'ipconfig' look like once you 'connect'?

Looks like I am connected to comcast.

> Do you have a vpn IP and a physical IP?

Not that I can see.

> Can you ping the default gateway for each?

No.

If not, what are the results?

I don't see a gateway for the VPN.

What is your company's network/security engineer saying?

He wants me to bring the PC in, but that is difficult. I am in
Colorado, the company is in Virgina.

I can not do anything the remote network.

Do you have the windows firewall enabled? If so, disable it then
retry? Any other security software that you know of? You should see
an IP for your LAN as well as an IP for your VPN or something is not
working. I would suspect windows firewall or something similar for
starters.

The windows firewall was on. I turned it off, but the VPN still does
not work. I am also running Mcaffe, but that does not seem to be
blocking anything.

Any easy way to check for closed ports with XP?
