We did a WSS 3.0 & SP 2007 service pack 2 update a month or so back. For the past 2 weeks, the Sharepoint site has to have IISRESET done on it in order for the site to come back up. Works great during business hours. We don't have an exact time as to when it goes down. The event logs don't show anything special at any specific time of night showing that something catastrophic has occurred. We checked our Backup Exec and vRanger backup jobs and they are continuing to work exactly the way they have been, all successful. Once IISRESET is done, the site works perfectly for the whole day.
I checked the IIS logs as well as SP logs and find nothing of substance. Stumped on this one. Anything anyone can think of? We have a gal who's having to get up every morning to reset the darn thing. We contemplated writing a batch script / scheduled task to just reset it in the morning but that isn't fixing the issue of course. Tried googling this issue but figured I'd tap EE's knowledge while trying a few things.
