can you give us some sample data?

?????
post your code

textBoxName.Text = DateTime.Now.Month.ToString()+"/1/"+ DateTime.Now.Year.ToString();

it depends on how that column is setup in the database. Is it set up as an identity column?

I see your problem, it's simply, oh wait I can't see anything because you didn't post any code, didn't say what you were using to send the email, no useful information whatsoever.

Might as well go...

i cannot even ping that address. You probably need to talk to your network administrator. This looks like a networking problem, not a ASP.Net problem
