HI,

I have a Problem in my sbs 2003, since yesterday:

When i connet OWA form internet i receive this Text:


503 Proxy is busy - A connection to the server could not be made because the limit on the number of concurrent connections for this account has been reached. (1238)

What is the cause of this error message and how can I fix
