More errors

Ok today, I actually have an error to report
THings were bogging down on the server and users could not get into
Vantage. They would get the splash screen and that was it.
Then my accountant opened report builder and got the following:
Unable to connect to database. Database error is The server or the
system has no more resources. Try a larger -N [748]**Server rejected
login (700). Does this help anyone in diagnosing my problem?
