URGENT: A call to SSPI failed

[Great Chap]

Hello Everyone,

I am using MySQL connector 6.9.11 and it connects to db in my linux server. Today suddenly I get error "A call to SSPI failed, see inner exception.". Inner exp is "The Local Security Authority cannot be contacted".

My code is in VS 2010 and uses .NET framework 4.0

CODE

UN="username"
PW="password"
connStr = String.Format("server={0};user id={1}; password={2}", "www.mysite.com", UN, PW)

Conn = New MySqlConnection(connStr)
Conn.Open()
----------------------------------------

What to do? This happened suddenly as program has been working fine for years.
