I have a couple of PC’s running windows 7 pro SP1. I am trying to setup remote desktop connections for user to logon from home. All I keep getting is the cleint could not establish a connection to the remote computer.

Then giving 3 possible solutions.

1)remote connections not allowed

2).maximum nuber of connections reached

  1. network problems.

I can connect to both these PC’s via RDP from with in the office domain. It is just when I am outside that problems occur.

Looking for suggestions, ideas , Solutions

Setup each machine with a static IP, then (assuming you have enough free outside-accessible IPs) poke holes in your firewall on port 3389 allowing traffic from any outside port to hit the inside IP on port 3389. You’ll have to eat up a publically accessible (i.e. outside) IP per machine on which you want this allowed.

Or, install LogmeIn on each machine that needs to be remote controlled from the outside. Far easier, and will probably get you what you need without the above fuss.

You didn’t mention how are they connecting to your LAN at work from home? VPN?

Is your office LAN behind a firewall?

Do the users all have remote login privileges?

Are you connecting by host name or IP address? If you are using host name is your VPN providing DNS?

Try setting up a log me in session just to test, rather then using remote desktop, see if you can connect. Also a simple one, when using remote desktop, double check to make sure you have entered your domain name correctly.

Do you have a firewall set up where you are? Could that possibly be blocking remote connections?

6

yes it is behind a firewall. Rules are setup to allow the tcp port through.

This works for certain machines but not the two i need it to work.

All users that require it have remopte access privelges.

The PCs in the office have activate the RDP?

Do you use a VPN?

Take a look to DHCP, maybe it changes the IPs when the machines are rebooted

Look to you GPOs, maybe you have something prevented their access

8

The user are using a static ip to our router with a tcp port number and these then have firewall rules

9

In the VPN properties, under security tab, Type of VPN, is it set to automatic? Try PPTP.

10

And this system work fine for 3 users

11

Are the other machines for which this works running different OS? Firewall is better in Windows 7, perhaps you need to make some changes to the clients’ firewall settings to allow this traffic.

12

Are you connecting by host name or IP address? If you are using host name is your VPN providing DNS?

13

Setup a Gateway server. Poke hole in Firewall to just one machine (the Gateway) and then setup the rules on the gateway to point the certain user ID to a specific machine. Less holes in your firewall.

As with another post I saw this week (& from personal experience) were these new PC’s installed by you or pre-built with a pre-installed Anti-virus/Security package?

Did you remove it?

Did it un-install completely?

I have know both Trend & Norton leave firewall components behind when “uninstalled”. Check in services for residuals.

That’s why I prefer to build from scratch or image PC’s from a “hand-built” original that way only what I want on is on.

You don’t give us enough info to troubleshoot your setup. Since RDP works when you are on the LAN but not from outside, it may be a network firewall issue. What ports do you have opened on the external firewall, and how are they forwarded? How are you trying to connect externally? Exact commands and/or screenshots would be helpful. Just change IP addresses to XX.YY.ZZ.AA if you’re shy about posting them in public here :wink:

It looks like he fixed it on his own.

You can see his other thread started on (essentially) “Why does what I did to fix it help?”

17

Yes all fixed. It was a registry entry after all that. But thanks for all the help
