Hi Jim,
I have never had to change the content server name but I have restored from a backup before. First Terminate all axistv services through configure device in the start menu visix folder. Make sure you check and see that all services say they are stopped there is usually 1 or 2 services you have to do manually again to stop them.
Second replace your Binary storage folder, may take some time.
Third, you have to go into the database manually through the mysql server management studio express click on databases, then right click on AxisTV go to restore, database. Then a window pops up and click on the options tab on the left and check the box that says Overwrite the existing database. Then click the general tab click the specify from device tab, browse for the .bak file that visix backups on your drive in the AxisTVBackup folder. Then click ok and it will restore the database.
Then restart your computer and it should be working.
Sorry for the delayed response I didnt know you wrote back.
