NT4 SP3 IIS4 HELP!

Hi, I have developed several applications in ASP that used to directly connect to the Informix databases using ADO via IConnect and the Informix supplied ODBC drivers (the Informix drivers where very flaky) on NT4 & IIS3. When I upgraded the servers to IIS4 there seemed to be a direct conflict between the MS Oracle ODBC drivers & the Informix ODBC drivers that messed up the server to the extent that I had to reformat the machine. My current version of CLI is 2.50.TD2....... (not installed on the servers for obvious reasons). If you could confirm that what I am doing is possible under my current configuration (maybe you know of other developers taking this aproach?) then I could contact my Informix sales desk, get the revised CLI software / ODBC Drivers and get these applications running again. Heres the current standard configuration of the NT servers that I need to be able to get talking to the Informix servers. NT4 Server Service Pack 3 IIS4 NT4 Option Pack FronPage server extensions. The Informix servers run on AIX and are a mixture Online & SE ver 5.x/7.x Thanks to everyone taking the time to help me out here, Matt Deards Intranet Developer.
