SQL Server replication subscriptions marked as inactive Is there any way to force SQL Server NOT to mark subscriptions as inactive, ever?

It happens sporadically when there are connection issues and I don't want to have to reinitialize the subscription every time.

Note, I'm not talking about the subscriptions being marked as expired...just as inactive.

We have retention set to 0 (infinite). I'd rather have a big distribution database than have to reinitialize a 15GB database to a subscriber over the WAN. Anyway, the real issue here is that they are getting marked as inactive within just a few hours sometimes...or sometimes a few days...it seems sporadic. Is there any way to tell WHY SQL decided in its wisdom to mark them inactive?
Yes you can do that programatically using t-SQL and a sql agent job.

Basically, you have to query distribution..MSSubscriptions and check the status column value to be 0 (Inactive).

Status of the subscription:
0 = Inactive; 
1 = Subscribed; 
2 = Active

Below T-SQL Will help you :

-- publisher_id
-- publisher_db
-- publication_id
-- subscriber_id
-- subscriber_db
select * From distribution..MSsubscriptions

--- based on the above values, run below statement
--- this can be run using SQLAgent job

if exists (select 1 from distribution..MSsubscriptions where status = 0)
begin
UPDATE distribution..MSsubscriptions
SET STATUS = 2
WHERE publisher_id = '--publisher_id -- will be integer --' 
    AND publisher_db = '--publisher db name ---'
    AND publication_id = '--publication_id -- will be integer --'
    AND subscriber_id = '--subscriber_id -- will be integer ---'
    AND subscriber_db = '-- subscriber_db ---'
end
else
begin
print 'The subscription is not INACTIVE ... you are good for now .... !!'
end
