Changing the DSCC hostname
As I've already seen several people meeting this problem, here's a quick
article with the solution. When you change the DSCC registry hostname after
installation, you can't access the DSCC GU anymore. Actually, the DSCC webapp
needs to know where to find the DSCC directory, since it serves as the DSCC
repository. So you need to change the parameter below in the DSCC web
application configuration, which is located in the DSCC web.xml file, and then
restart the application.
