Remote Desktop Connection woes... black screen with Earthlink ADSL

[Guest]

ok, here's a fun one, and I could use some help!

I have 2 laptops
1 mac and 1 pc
I have Remote Desktop Connection on both of them
when I try to connect through my home dsl, I get a black screen. But if I
bring either of the laptops to one of the multiple outside coffee shops... It
works perfectly!

I've tried a bunch of things at home including
1 connecting directly through dsl modem, skipping router
2 using router with laptop listed as the dmz IP
3 forwarding port 3389 directly to the laptop

nothing seems to work,and I just get a black screen

any idea?
I even tried (or think I tried) setting the mtu size... b ut it didn't seem
to work either

thanks!

Start by running some tests with telnet.exe, e.g.

telnet NameOfDesktop 3389

By the way, what operating system does your desktop run?

ok! tried to run telnet, and the command prompt goes blank, and the cursor
goes to the top of the window like something is about to happen, but nothing
does. Then if I hit any key, it goes back to a prompt.

the remote desktop is running windows 2000 server

is there any way to check why the telnet is failing? I also don't know if
I've set up the server for telnet, although I have been able to use remote
desktop connection when connected through other dsl/cable accounts (if that's
the same thing)

thanks!

If you had tried the telnet command on a PC that can successfully
set up a working RDP session then you would have noticed that
the behaviour you observed is normal. This is what telnet does
when it accesses an open port!

The test proves that port 3389 is open on your target PC. The
RDP problem you experience is probably due to incorrect DNS
settings on the host PC.
