I'm working on a Windows 2003 server trying to connect to an Oracle database on a 2000 server and all was working fine. I've been trying to get PHP to work with IIS6 and changing some settings in Windows and IIS and all of a sudden I can't get an Oracle connection at all through enterprise manager or the net configuration assistant. I get the error: Ora 12705 Invalid or unknown NLS parameter value specified.
I get the same error when connecting to a different database also.
Both database connections worked before. I have tried changing the registry entry for NLS but that didn't make any difference, It is set as ENGLISH_UNITED KINGDOM.WE8MSWIN1252 which is the same as another machine that connects just fine.
Perhaps even more stragely I can connect in SQL Plus just as before and query the database with no problems.
