The following fatal error occurred in the Remote Web Workplace application:
  URL: https://XXXXXXX.dnsalias.net/Remote/client.aspx 
  Error Message: Die Eingabezeichenfolge hat das falsche Format.
  Stack Trace: bei System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
bei System.Number.ParseDouble(String value, NumberStyles options, NumberFormatInfo numfmt)
bei System.Double.Parse(String s, NumberStyles style, NumberFormatInfo info)

bei System.Web.UI.Control.OnLoad(EventArgs e)
bei System.Web.UI.Control.LoadRecursive()

The error message means: The Input has the wrong format

Is there someone attacking me? Trying to provoke a Buffer Overflow or something?

Thanks for your help

What is the event you are getting on the server?

The eventid is 0 the source is SBS.RWW
English would be nice, ;-) but it appears you are using dynamic dns which could be more than likely causing your problem. Not saying this is your complete problem, but I would never run SBS using dyndns, why can't you get a static IP address?

@shree, go figure if ms updates would do this :-). If that turns out to be the problem, I still would like to know about the dynamic dns on an sbs server, never seen that before.

the dyndns is made by the router.
i forwarded 443 a.s.o. to the sbs

but this works for 3 years now.
i think that there is someone writing dumb shit to the logon-screen
