Remote desktop connection not working

z0mbi3 · 22 Oct 2007 at 09:30

Weird problem both myself and my mate have been having recently with remotely connecting to our Vista PCs.

It seems that Remote Desktop no longer works and it seems to be due to an update that's occured over the last month or so.

Basically, manual configuration wise, nothing has changed on our PCs yet when we try to connect we're getting "can't connect to the remote computer" errors. This was previously working. Found out that if we turn off Windows firewall then it works again. Thing is Remote Desktop is definitley on the allow list and Remote Desktop is definitley turned on and set to accept connections :confused:

I can only put it down to a Windows update changing something as I genuinley haven't changed any other settings.

Any one have any ideas?

Still having the problem

Is that the only firewall you're using? If it's already on the exceptions list i'd remove it then readd it again. This will make sure that it's using the correct port incase you changed it.

z0mbi3 · 23 Oct 2007 at 09:43

Definitley the only firewall. I've already re-added it as an application as well the port and it's still not working :confused:

hmmm very odd, yet it works with no firewall enabled?

Did you disable it on the machine you were connecting to or the one you were connecting from?

z0mbi3 · 23 Oct 2007 at 10:48

If I disable it on the machine I'm connecting to it works fine.

Have you tryed adding the users to the allowed RDC users list?

z0mbi3 · 23 Oct 2007 at 14:33

Yup, sorry I should have put all this in the OP, I've checked and the account I'm logging in under is definitley on the allow list.

Get another firewall and kill windows firewall

Reset the Windows firewall.

Open a Command Prompt window and type NETSH FIREWALL RESET

How about this, just confirms what you've already stated but might give you an idea as to what to look for:

I was hopeful this would fix it it but just tried again this morning and it's having none of it.

Not recently, upnp is on on the router/nat. Where do I check under vista?

firewall exceptions

are the ports forwarded in the router..?

might be easier just to install hamachi

z0mbi3 · 24 Oct 2007 at 11:52

hamachi isn't an option, besides I want to fix this rather than work around it.

Remote desktop is on the exceptions list, I even manually added port 3389. Is there something else I should be putting on there?

edit:

thanks for the help btw

You could try port scanning one machine from another on your LAN, just to see if any listeners are open.

Something like LanSpy or AngryIP Scanner would do the trick.

Baz · 24 Oct 2007 at 12:09

Are you using the machine name or its IP address ?

z0mbi3 · 24 Oct 2007 at 12:12

IP.

As I say this has all worked previously.

I'm going to try port scanning with Shields Up when I get in from work.
