Try this make a shortcut on your desktop of your wallet in question, then right click that icon shortcut, go to Properties, edit the target line and behind the .exe space -server as such
Example: D:\Fastcoin\fastcoin-qt.exe -server
Save changes, exit/close that wallet if open then use the shortcut to reopen the wallet.
Make sure you have created a xxxx.conf within the wallet folder first before reopening the wallet with the new shortcut, also should be named to match the coin or wallet.
Example: C:\Users\TheWolf\AppData\Roaming\Fastcoin
The inside of this fastcoin.conf looks as so for solo mining.
This line should not be needed rpcallowip=192.168*.* unless you plan to mine with other computers back to the main rig that holds the wallet.
No since in having more than one wallet address. ;-)
