Internet Information Services (IIS)
While not recommended, DSA Web Server can work with IIS and other web server applications on the same Windows Server environment.
In such environments, DSA Web Server will be forced to redirect its connections to port 8000 (instead of the default port 80) and users will have add that to their URL address for logins. Port 8000 also requires extra steps when uploading out of the box reports to DSA Web Server.
We highly recommend deploying DSA Web Server on a dedicated environment (such as a VM) free of IIS and other applications that might use port 80.
