I haven't worked with Foxweb 1.x in a long time, but I believe setting this up is not much different than the 2.x product.  The steps are:

1. Open Control Panel and Locate Services and open it.

2. Locate the Foxweb service and once you have found it click the "Startup...." Button. This will display a window with "Startup Type" and "Log On As:"

3. In this window select the radio button "This Account" and click the "..." button at the end of this line.  This will bring up the user dialog, select your user from the list by double clicking the name and the clicking the "OK" button. Your user name should now be displayed in the "This Account:" text box.

4. Enter the password for this account and confirm it.

5. Click the "OK" button.

6. Click the "Stop" button in the Service window (make sure Foxweb is still your selected service)

7. Click the "Start"
