Enable Hidden Files if you haven't already - http://windows.microsoft.com/en-US/w...w-hidden-files
If you still can't find it, try this method:
1) Right click on My Computer, select Properties.
2) Go to the Advanced tab, and select Environment Variables in the Startup and Recovery section.
3) In the Environment Variables section, under "User variables for USER", create a New variable called ADOM_HOME.
4) The value for the variable should be where you want your adom_dat folder to go, so select something easy, like the desktop.
For example, C:\Documents and Settings\FantomFang\Desktop
With that done, you've relocated where ADOM saves its games and stores its data. If you still fail to load ADOM, there's most likely a more serious problem going on, as you shouldn't run into problems with adom.prc with the brand new home directory.
