Solved: New LAN = Remote Desktop no longer works
Hi, everybody!

Thanks for reading! I've been reading this forum for a couple hours now, and am actually a bit more confused than I was. I'm certain the answer is in here somewhere, but I'm not having any luck, or I am misunderstanding something.

Basically, I rebuilt my network over the weekend, to include a subnet, and can no longer connect my desktop to the remote PC. My old router was reset to defaults and re-configured. My PC has been wiped, reinstalled, and fully updated.

The error I receive is "Remote Desktop can't connect to the remote computer for one of these reasons: etc" I've only seen this error in the past when the PC I connect to was powered down. I have confirmed that everything is still set up properly on the PC I'm trying to connect to via an associate, and it is not powered down.

There is NO WIRELESS ANYTHING in either setup below:
(also, ignore the ....s. or some reason, it's deleting the spaces I entered when I preview the post)

Old setup:

[My Win7 PC] ---- [old router] ---- [modem] --- [internet] ---- [Remote PC (Win 7)]
...............................| | |
.........................other local PCs

New setup:

[My Win7 PC] ---- [old router] ---- [new router] ---- [modem] --- [internet] ---- [Remote PC (Win 7)]
.........................................................| | |
...................................................other local PCs

1. I went into Windows firewall to allow Remote Desktop through, but it looks like that only needs to be set for the PC I'm trying to connect to. (Yes/No?)

2. I've forwarded port 3389 from the old router to my PC.

3. I haven't done anything yet to the new router, because I really can't tell if I'm doing the right things. The very first time I connected to the remote PC, it went right through, and I didn't have to change anything in the old router (I think - it's been awhile). I really don't know where to go from here, and it looks like the setup options I've found in the forum so far (static IP, port forwarding, Windows firewall changes, etc.) leave me with more security risks than I had on the old network, and there seem to be some conflicting opinions about the setup process.

I can find my way around both routers fairly well, but I've never had to deal with setting one up to connect remotely. If anybody could provide/help me find some guidance, I would be so thankful.

Nothing you did on your PC or with the routers should matter. Something must have changed with the Remote PC. Are you using a dynamic DNS service to access it? Or just using an IP address? Either way, make sure you are really addressing it.

Thanks, but it was actually a VPN problem. Everything's working fine now.
