application stops working sometimes

[Nikhil Patel]

Hi all,
I installed an asp.net application on a client's machine on Friday. It
uses a Sql Server database as backend. Database server and Web server are on
different machines but same domain. The IIS virtual directory runs under a
domain account. So I gave database access to this domain account in Sql
Server. And the application was working fine. But when the client tried if
on Sunday, it did not work. It gave the error that either sql server was
missing/not running or denied access. So I myself tried it this morning and
it was not working. But strangely it is working now. So do you think, the
client is doing something that allows or stops application from running or I
am doing something wrong? Also is there anything I should do to prevent the
error from happening again.

Thanks.
