Home -> Community -> Usenet -> c.d.o.misc -> Re: Can't connect to Oracle using MSDAORA OLE DB provider
Thanks for your reply. Everything that you mentioned has been set
correclty. I can connet to Oracle from Access. I can view Oracle data
tables in Oracle enterprise manager console and SQL Plus But I can not
connect to oracle in my application. This application workes fine in
another Windows computer. I am in the middle of setting up a new
computer for running this application. I suspect that something
different in the OS which causes this problem.
