Good evening,
This morning I install the terminal services client on my computer at work an dit worked, of course I was connected to the LAN where the servers are, I took this computer home and now that I am setup and I was tryin to see if my terminal services client works it keeps giving me an error "Terminal Services client disconnected" The client can not connect to the terminal server.
The server may be too busy.Please try connecting later. I am using the 32 bits client. Why am I having this problem, I know the IP address that I have typed in is correct, do I need some type of VPN in order to connect or what am I doing wrong, Please advise since I am sore of new at this, I am going to be away from the office and I thought that by installing terminal services clinet on my computer I could check on my servers at work.
Thanks for your support and cooperation
Sincerely
Mariae

Mariae,

I do hope that your work servers are behind some sort of firewall. If so, your best bet is to use a VPN to tunnel in and then you won't have to change any settings on your TS client [you can use your servers names or IP addresses as you know them.] Otherwise, you will have to have PAT [port address translation] TCP/3389 to the server behind the firewall you want to connect to.
YOU-->FirewallIP:3389-->PAT to internal server 10.10.10.50.
This will work with only one server though. To check multiple servers, you will have much better joy using a VPN.

Hi KingHollis,
Yes, my servers are behind a firewall, but I thought using terminal services was a good idea, how easy is to set up the vpn client in windows 2000, can you give me directions as to how to do it and aso do I need any sort of licensing for this or not.
Thanks for your prompt response and cooperation.
Sincerely
Mariae

Mariae,

Your thought was right-- using terminal services is a good idea. It just requires a little advanced planning. Setting up a VPN from a windows 2000 client standpoint is relatively simple and straightforward. From a firewall perspective, the simplicity will be determined by the device being used. Do you control your firewall or does someone else? What model is it?

KingHollis,
I do control the firewall and it is a Sonicwall Pro.
Thanks for your support.

Mariae,

SonicWall Pro comes with Global VPN Clients and there is a configuration screen for VPNs on the SonicWall itself. It should be pretty straight forward. Just make sure the client configuration matches the SonicWall's.

Hi KingHollis,
No I did not, the VPN global client does not support my firewall, since I have an old one, and lately I have been trying to get the communication from the VPN client of Sonicwall to my work, but it is not working, I have been going back and forth with technical support but so far no luck , I did not think this was that difficult, now should I ried doing from the Terminal services, of course when I tried it, it did not work, or try the VPN from windows 2000, what do you think is  a best bet, now I really need it since I am only working parttime sometimes I would like to get things done from home without having to go to the office, at hoem I have a firewall and that's what sonicwall was telling that there may be some communication errors, but I need the firewall at home.
If you need any more information please let me know, and I do appreciate the fact that you want to know how this is going.
Thanks so much for your support and cooperation.
Sincerely

Alright Mariae, let's see if we can get this thing sorted.
Questions:
1. Is the work SonicWall firewall already configured to accept VPN clients? How are internal addresses issued to clients that connect to it-- DHCP server on your network, or does the firewall have a static set it issues?

2. What model of firewall do you have at home? Do you have DSL, Cable, what? Were you issued a static public IP address?

3. What operating system do you have on the computer at home? Windows 2000?

Forget the VPN Global client if your firewall doesn't support it. Setting up the Windows VPN client is as simple as running a wizard. But I am concerned that if the Global VPN client doesn't work [or is not supported], you may not be able to use the Windows VPN client either. This shouldn't be the case, but there are solutions/workarounds we can use.

My other concern is that your firewall at home may not be configured to allow VPN traffic in/out.

There are a couple of possible solutions, but they will be better determined by your answers to my questions above.

A. You could create branch-to-branch VPN connection. In this solution, your machine at home would be configured with a local address of your work network [ie 172.27.1.25] and your firewall will act as the endpoint for your VPN tunnel with the other firewall at work.
                                                           _______________
       172.27.1.25/24--HOME FIREWALL >__VPN TUNNEL___>SONICWALL--172.27.1.0/24

B. If your work has another public IP, you could get another inexpensive firewall device that has VPN capabilities and use it exclusively for VPN traffic.

        SONICWALL--------
                                   |------------172.27.1.0/24
        LINKSYS------------

We can continue to explore the solutions until we get it right!

Hi KingHollys
The firewall at work is configured to get the VPN client, about a year ago it was working, I did notice that ist says disabled, I don't know why, but it does, I checked with the settings and there is no where that could enable it, I will ask techical support from Sonicwall, anyway, and yes is through DHCP on the network.
The firewall that I have at home is a Siemens Speedstram wireless dsl/cable router, and I have cable at home and no I was not issued a static IP address, and I am using windows 2000.
I will try the other solution on Monday when I am at work.
thansk so much for your support and ccoperation.
Sincerely
Mariae

Anytime! I just hope we can get it sorted! Sounds like if the work firewall has VPN disabled, you will not be able to get through unless the folks at Sonicwall support can get it working for you. I believe your best bet is going to be to get a second VPN/firewall device with a seperate public IP address and use it exclusively for VPN access. This way, you won't have to change the role of the current work firewall. Or, replace the Sonicwall with another more robust VPN/firewall device. But then you will have to configure all the settings to mirror the access control you had configured on the old Sonicwall.

Keep me posted!
