Try this. ^([A-Z])([a-z])([+!_%&])([0-9]{5}) ([A-Z])- will allow only if first letter is caps ([a-z])-secondletter shud be lowercase ([+!_%&])-third character shud be symbol.I have added only few. ([0-9]{5})-then it should be followed by 5 digits Regarding password should expire in 6 months you have to set that in Database. in User table have password changed date where you insert current date and whenever user logisns validate it crossed 6 months or not sample code: ErrorMessage=RegularExpressionValidator ValidationExpression=^([A-Z])([a-z])([+!_%&])([0-9]{5}) ControlToValidate=TextBox1/>
