Vasichko Posted January 12, 2005 Report Share Posted January 12, 2005 Ok I have a small network, I have a server and 5 client PCs. I have my RAS and VPN established. My server is running Windows 2000 Server, and all the clients XP SP2. When trying to access using Remote Desktop Connection, it gives me an error saying the PC may be busy or the network is unaccessable. Could you guys help me out a bit and let me know what may be the problem.I do have the clients set up to be accessed remotely. Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 I am trying to connect to the computer remotely using the IP address the my DHCP has leased to the desktop. Quote Link to comment Share on other sites More sharing options...
scuzzman Posted January 12, 2005 Report Share Posted January 12, 2005 I assume the computers are communicating? IE: ping's are passing, etc.? Quote Link to comment Share on other sites More sharing options...
scuzzman Posted January 12, 2005 Report Share Posted January 12, 2005 Afterthough - are there any firewalls on the computer? Also - your DHCP - what is it? Linux computer/server, router, Windows server...? Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 The leased IPs are working fine. I can access the net works great. The DHCP is Windows 2000 Server. I have a Dlink firewall. Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 12, 2005 Report Share Posted January 12, 2005 You're aware that Remote Desktop allows you to take control of the Server or the Desktops? Are you trying to use Remote Desktop to talk to the client (XP) machines from the Server, or vice-versa?Why do you have to use RAS and VPN? Do all of the PC's have a common Gateway or Router? Are they all on a common LAN?If you have a VPN established, you probably won't be able to get to the tunneled PC's from the LAN while they're VPNing. Do they create a VPN session to the server, or to a remote network? Quote Link to comment Share on other sites More sharing options...
scuzzman Posted January 12, 2005 Report Share Posted January 12, 2005 Have you tried maybe some other software than Remote Desktop - such as VNC? Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 Their access to the internet is through 1 server and 1 firewall. I am wanting to access the clients desktop so I can have access to some applications on them from a pc at another location. What is VCN???

scuzzman Posted January 12, 2005 Report Share Posted January 12, 2005 VNC is a remot configuration utility - there's a free version here. Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 12, 2005 Report Share Posted January 12, 2005 Once they're tunneled, you may not be able to get to them via the Server. They're VPN'ing to gain access to the Internet. Your Server's IP is on the LAN. Have you hardened the Windows 2000 Server? Have you considered using a product like Microsoft ISA Server, or getting an inexpensive Router/Firewall?

Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 So since Im leasing an IP address on the client pc's it is impossible to remotely connect to their desktop??? Quote Link to comment Share on other sites More sharing options...
scuzzman Posted January 12, 2005 Report Share Posted January 12, 2005 If you're trying to connect externally, then Port Forwarding would need to be configured in the firewall before you can remotely administer the machines. If you're on the internal network, you can simply use the IP address. Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 Thats what Im trying to do. Login using Remote Desktop, by using the IP that was leased to that machine and use some applications.So what do I need to do with this port forwarding??? How do I do it???

homecomputeraid Posted January 12, 2005 Report Share Posted January 12, 2005 Once the tunnel is up, the PC's will use the VPN Adapter's address for their primary route. The configuration you describe is problematic if you want to be able to both browse the Internet strictly via VPN tunnels, and browse among the PC's on the LAN. You may be able to do split tunneling by telling the LAN PC's not to use the remote gateway in the VPN Connection Properties. Are you using the built in Microsoft VPN Client? If so, you make the change as follows:Right click My Network Places and select Properties, then right click the VPN Connection and select Properties. Click on the Networking tab and click on TCP/IP:Click on Advanced, and uncheck the Use default gateway on remote network to allow the PC's to "see" both the LAN, and the VPN Tunnel Networks.

Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 Now do I do this on the clients??? Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 12, 2005 Report Share Posted January 12, 2005 Yes, on the clients. Just making sure here, the Server is not VPNing is it? Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 No not VPNing. Clients are just getting an IP leased out. Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 Actually right now Im remotely connected to the servers desktop, and I cant even remotely connect to a client pc.... Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 Im logged in and WAN Miniport (PPTP) (VPN3-4) is active, so yes Im VPNing. Quote Link to comment Share on other sites More sharing options...
scuzzman Posted January 12, 2005 Report Share Posted January 12, 2005 The clients are allowing a connection correct? Meaning they have the servers running? Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 12, 2005 Report Share Posted January 12, 2005 I'm not sure why you wish to VPN. Virtual Private Networking is a process for setting up a secure encrypted "tunnel" across an unsecure network like the Internet. Once traffic is tunneled, it's like you aren't on the original LAN. It appears to the tunneled PC like it's on the remote network (in your case the Internet). Wouldn't you be better served by Internet Connection Sharing, or a Router/Firewall? Your topology would be greatly simplified if you just used a Router/Firewall to protect your PC's, and let them communicate with each other on the LAN. You can get a Router/Firewall for less than $100.The only place I've seen VPN used in a situation remotely similar to yours is when there is a wireless LAN involved. In that case though, the wireless users connect to a DMZ, not to the LAN itself until they authenticate. Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 Well when I access the server remotely I am VPNing. When Im on a client pc, its just getting an IP leased out to it, its not VPNing. Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted January 12, 2005 Report Share Posted January 12, 2005 When you say accessing the server remotely, to you mean from you LAN using Remote Desktop on one of the PC's, or do you mean remotely from outside your LAN coming in?How do your PC's get to the Internet? Do they all use a common Router (gateway), or does your server have 2 Network Interface Cards? Quote Link to comment Share on other sites More sharing options...
Vasichko Posted January 12, 2005 Author Report Share Posted January 12, 2005 I am accessing it from outside the LAN coming in. Yes they do use a common router... Quote Link to comment Share on other sites More sharing options...
