"query notification" problem

I am using query notification and have the following problem:
I tegister once, then change the DB table manually to test. a msg is printed
to the log proving the call back function was called. I can repeat this
several time.
BUT, I then go away for 10 min', and come back. Now, when I change the data
in the DB nothing happens!
any clue how to fix and undertand this?
thanksUPDATE:
I used trace to see what is going on in the database. So I see that I get
"subscription fired" followed by "subscription registered" everytime I do
changes to the database.
After I stop doing any changes to the database for 5 minuts, and re-change
the data there, I see the database fire the "subscription fired" event, but
this time there is no "subscription registered" event. I also do not get the
log printout that I have in my web ASP.NET application, that is supposed to
write a line in the callback function.
So the hear is the deal:
The callback function gets the event fired for the first few times, so I am
doing the registration right. but, somehting happens to the ASP.NET
aplication, or the DB connection or something, that causes the callback
function not to be called after a certain time. anyone has an idea of what
am I up against? why is this happening?
thanks|||Any idea what is this error I get?
The query notification dialog on conversation handle
'{2FD61BF6-44B8-DA11-8B4E-00123F74CFF6}.' closed due to the following error:
'<?xml version="1.0"?><Error
xmlns="http://schemas.microsoft.com/SQL/ServiceBroker/Error"><Code>-8490</Co
de><Description>Cannot
find the remote service
'SqlQueryNotificationService-657d36e5-7654-44a2-8137-5ec5e3417cc4'
because it does not exist.</Description></Error>'.
?|||It means that service named
'SqlQueryNotificationService-657d36e5-7654-44a2-8137-5ec5e3417cc4' does not
exist in the database where the notifications should be delivered to. Seems
like you are adding the broker instance at the end of the service name. The
service name you pass to the SqlNotificationRequest.Options must match the
service name you created in the database.
