Frågan#1
Hej,
Jag har problem med att en site inte startar upp igen efter att app poolen har kraschat.
För att få igång siten igen så måste jag gå in i t.ex. web.config och slå ett radbryt och spara om filen, då hoppar sidan igång igen.
Finns det något jag kan göra i kodväg för att förhindra detta eller finns det något som webbhotellet kan göra på servern?
Själva felet nedan är att SQL servern inte hittas, förmodligen håller den på att startas om eller nått!
