Java remote desktop protocol from Windows server -no valid license available(0x102)

Question

This works from my iMac but not from my MacBook Pro.
Our work offers a Java RDP. First I have to log on to the server which I can do. Then I could use a Citrix client function, if I wanted to figure out how, but the alternate Java interface used to work on both computers, but now only on one.
Various websites have directed me to where the license is, saying to delete it, e.g. HD -> Users -> Shared -> etc. It isn't there or anywhere else that I can find (Library, Applications, Preferences, Application Support, both at the HD and User levels ... I have looked around).
Some of the things I see on my screen are these:
Terminal Services (RDP - Java) - one would click here to activate the password-protected software I need to run
Terminal Services Java Client Error
Connection Terminated
No valid license available(0x102)
The terminal server disconnected before licence negotiation completed.
Possible cause: terminal server could not issue a licence.
IT at work doesn't seem to know what to do. They have directed me to instructions about deleting a listing in the Windows Registry - clearly not directly applicable on a Mac.
Anything obvious I could do about this?
Thank you.

P.S. I can circumvent this with an SSH tunnel from my MacBook Pro to my iMac - but it slows things down and I think shouldn't be necessary.

Answer 1

Thanks, Linc. I previously looked at the CoRD page and felt intimidated and then forgot about it. I've downloaded and run it now and my feelings were justified.
I put in the settings I know, which are something like:
     https://xxx.xx.x.xxx/cgi-bin/welcome/{users_name}
and it simply fails at that point.
It works from IE or Opera (within Fusion, Vista), but not from Safari, and I haven't tried it with Firefox for Mac etc. because of complicated reasons ...
So CoRD says:
     Couldn't connect to {name_I_used}
     The host name could not be resolved.
So honestly, I've looked through the help files, read about "Connection Preferences" and looked at the "Connection Inspector" and it's all "computereze". It says I may use my user name and password or not - neither way works. When I go through IE (or Opera, from Vista), then there is a domain specified in a 3rd field, and it does't matter if I type that word in the Connection Inspector "Domain" field or not.
I had an idea it would be complicated.
Anyway, in the meantime, I'm managing through Fusion -> Windows_Vista. Actually, it's malfunctioning this morning as well, so this is just normal computer networking! Today, Java through IE wants to install MLWebCacheCleaner.cab... then I have to say "continue" to various security alerts 3 times ... and it's still not working, even after updating Java, rebooting Vista - so it might not be COrd at all. Will have to come back to it some other day ...
Thanks again.
