i have allready done such work. what you have to to is :

1-on your server share your program folder
on client, mappe a drive that point to that shared folder (\\myserver\myfolder). after that you now have drive Z: for example.

2-create a free table (not in the dbc) and put it on your program folder. this table will save the path of the mapped drive. you can put this code in your menu.

select pathtab
replace servpath with xpath (where xpath is a public variable.)

3-in the main form or code that launch the program, verify if the mapped drive stored in the table is active.
