this app wasinstalled as a windows service app.

for (int i = 0; i < g_pool_size; ++i) { session& sql = iter->second->at(i); sql.open(backname, connectString); }

It might be trying to show the dialog asking for the credentials if the connect string doesn't include them. But you really need to debug it yourself to find out where is it stuck, we can't do it for you.
