here's the problem:

both are on the same server.

so i have IIS as the front-end and the back-end is DSS.

IIS uses port 80 and DSS uses port 80 to stream media.

Now the questions are:
-is there a way to seperate the two if I host both on the same machine in the DC?
-if i were to physically seperate the two, say put iis on one machine and dss on another machine, can I still have both cases using port 80? So that, IIS is the front and DSS is the back?
