A successful local logon begins when a user presses CTRL+ALT+DEL. Winlogon and the GINA DLL collect the user's credentials and then send the credentials to the LSA. The LSA verifies the user's identity and then returns a logon success and the user's access token to Winlogon and the GINA DLL.
Most people do not commonly experience side effects with vitamin D, unless too much is taken. Some side effects of taking too much vitamin D include weakness, fatigue, sleepiness, headache, loss of appetite, dry mouth, metallic taste, nausea, vomiting, and others.
Other symptoms are excessive fatigue, daytime sleepiness, muscle weakness and vision problems. Children can develop a softening of the bones called rickets; in adults, osteomalacia or osteoporosis can occur. A vitamin D deficiency might play a role in the development of colon, breast, ovarian and bladder cancer.
