i've tried the beta 2 (server: Windows 2003 SP1, client: XP SP2) and got file transfer and telnet working perfectly. But the Full Control or View Remote Screen functions don't work.
The following happens:
After starting, i get the login box and enter my credentials.
Then a small rectangle appears which seems to be a start-popup. Then this small blue popup-rectangle turns to black and remains so forever. This apparantly should be the remote display, as i can make it look like a window ("normal" mode) and resize it. But i never see any remote desktop.
Any ideas? What can be wrong if file transfer is working just great.
I had a similar problem in the past connecting to my Win 2003 box, (see [URL=http://www.famatech.com/support/forum/read.php?FID=24&TID=10820]http://www.famatech.com/support/forum/read.php?FID=24&TID=10820[/URL]) except that in my case, the splash screen showed and then nothing appeared. I never got a response from Famatech, but it did "magically" resolve itself, I believe shortly after I installed the new beta license key.
You're not at all alone. I think a lot of people have this problem. I know I do. Which is particularly unfortunate since Office 2007, which I'm committed to, does not work with Radmin 2.2 very well. This might be fixed in Radmin 3, but I get the little inert black window just as you do.
I hope they fix things, or at least offer suggestions for workarounds, soon.
I had a similar problem too. This is what resolved the issue for me:
Uninstall RAdmin Server
Re-install RAdmin Server
Connect from RAdmin Viewer Client
It requests a license code - input the 60 day trial license code
It reports that it has saved the license code to the server and seems to work fine now.
Basco Shower Enclosures
When I reinstalled, it never asked for a license code--same little black window result.
When I manually entered the license code on the remote server, the code was accepted fine, but no change from the viewer's perspective.
I think I'll have to wait until the next beta or something.
One slightly interesting new twist--for the first time, I tried right-clicking on the taskbar entry for the little black window, and when I chose (again) Full Control, the little black window reappeared with a title bar and the normal control icon set. Still inert and black, nothing there to see and no remote control ability, but I could manually resize the window and restart the remote computer, FWIW.
I am having the same problem. I have 3.0 installed on both my desktop and my laptop. I can remote into my laptop from the desktop just fine, but if I try and get to the desktop from the laptop, I get the black box forever.
