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.
Quick Answer. The Mayo Clinic cautions that vitamin D toxicity results in hypercalcemia, a build up of calcium in the blood that causes nausea, poor appetite and vomiting. Other symptoms of vitamin D overdose are weakness, frequent urination and kidney problems. Vitamin D toxicity, known as hypervitaminosis D, occurs when people take more than 50,000 international units of vitamin D per day for more than six months. The Mayo Clinic's recommended dietary allowance is 600 IU per day, but they also point out that overdose is relatively rare.
