får den fejl ved connection

Er det den rigtige ODBC driver, som du bruger?
Hvis du kigger under Regedit -> Hkey_local_machine/software/ODBC/inbcinst.ini kan du se, hvad det er for en fil, som ODBC indgangen/driveren gør brug af. Den skulle meget gerne hedde sqora(s)32.dll

ja det ser det også ud til at den gør. hvad kan jeg gøre?

den ligger i C:\oracle\ora9i\bin\sqoras32.dll

Jeg har set samme problem hos mig. Der er en fejl i rettigheder ved installationen.

Prøv det her:

Oracle 9.2 Client software requires that you give the Authenticated User
privilege to the Oracle Home by following these steps:
1. Log on to Windows as a user with Administrator privileges.
2. Launch Windows Explorer from the Start Menu and and navigate to the
ORACLE_HOME folder. This is typically the "Ora92" folder under the
"Oracle" folder (i.e. D:\Oracle\Ora92).
3. Right-click on the ORACLE_HOME folder and choose the "Properties" option
from the drop down list. A "Properties" window should appear.
4. Click on the "Security" tab of the "Properties" window.
5. Click on "Authenticated Users" item in the "Name" list (on Windows XP
the "Name" list is called "Group or user names").
6. Uncheck the "Read and Execute" box in the "Permissions" list under the
"Allow" column (on Windows XP the "Permissions" list is called
"Permissions for Authenticated Users").
7. Re-check the "Read and Execute" box under the "Allow" column (this is
the box you just unchecked).
8. Click the "Advanced" button and in the "Permission Entries" list make
sure you see the "Authenticated Users" listed there with:
Permission = Read & Execute
Apply To = This folder, subfolders and files
If this is NOT the case, edit that line and make sure the "Apply onto"
drop-down box is set to "This folder, subfolders and files". This
should already be set properly but it is important that you verify this.
9. Click the "Ok" button until you close out all of the security properties
windows. The cursor may present the hour glass for a few seconds as it
applies the permissions you just changed to all subfolders and files.
10. Reboot your computer to assure that these changes have taken effect.
Re-execute the application and it should now work.

Tror faktisk det var svaret!

tja, det lyder som en løsning. OK - pnielsen, jeg bøjer mig
