OO Base error: "file URL not correct"

[horst.graben]

Hello,

I. I am getting an error message when trying to open a form:

• OpenOffice.org Base
  (-) The connection to the data source "My Database" could not be established.
  The file URL is not correct.
  [OK]

II. I can click through the [OK] and enter the form

• but my ComboBoxes cannot read the tables they are based on. The next time I try and mopen this database, OpenOffice does not seem to recognize the file type and gives me a long menu of possible options (e.g., similar to the possible file format options in a "Save As" menu)
  
  But! this only happens under these conditions:
  
  (1) The database is hosted on a LAN server (E-Box on Ubuntu Hardy desktop), and is being accessed by another computer (tried 2 actually) running Linux (fresh install of Ubuntu Hardy). This problem does not occur when I use an Windows XP computer to access the database!
  
  ... or
  
  (2) Attempting to open a database on an XP computer from a Linux computer.
  
  And, several weeks ago, everything worked fine!
  (i.e., previous version of OO, and lots of other Linux updates ago).

HELP!

• Does anyone have a clue as to what is happening here?
  Can someone refer to to a more appropriate forum?

Thank you most sincerely for your attention!

Which version of OOo you use on Ubuntu, Ubuntu own or original from OOo site?
If Ubuntu try OOo from OOo site, Give the same results?

Try the official version: [Ubuntu] Installing OOo on Debian and Co.
Else, perhaps a firewall issue. Can you access other files (like text files, ...)?
