I installed 10.2 client on Windows 2000 Terminal Server. I created the system dsn odbc connection. When connected to the terminal server via RDP as a domain administrator, the odbc connection functions appropriately.
When connected to the terminal server console as a standard user, the odbc connection functions appropriately.
When connected to the terminal server via RDP as a standard user, I get the error:
"Unable to connect SQLState=IM004 [[Microsoft]][[ODBC Driver Manager]] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed"

I have reviewed the numerous other posts regarding this error and I've executed the following recommendations:
My oracle_home is defined first in my path environment variable (path - c:\oracle\client\bin;). I select my folder options (there is no security tab, windows 2000) I select sharing, then permissions. I allow 'Everyone' and 'Authenticated Users' full control, change & read permissions. I reboot the server. None of this works for me. Does anyone have any useful ideas?
Thanks.

You must set the Security policy "Create global Objects" for the user group, that uses Oracle 10 "

Just a summary of all the discussions
Assume Oracle Client in c:\OraClient folder and web folder as c:\inetpub\wwwroot

1. c:\inetpub\wwwroot must have Read and Execute privlege for IUSR user.

2. c:\OraClient must have Read and Execute privlege for IUSR user.

3. The environment PATH variable must have C:\OraClient\bin included.

4. Don't forget to restart Web Server
