We have a number of remote PCs 95, 2000 etc. which are running third party software. They are currently running 804 client but need to be upgraded to 817. The tnsnames.ora is also on a server not local machines by adding TNS_ADMIN to the registry. Have anyone implemented silient install of a client with only net8 and TNS_ADMIN? We need to simplify the install so nobody has to travel to those sites. I would really apprecitiate if you can provide some actual scripts.
