Never had problem concerning OWA so I'm a complete novice here.
Took over this firm that has had sporadic OWA problem where all of a sudden, it will completely disappear and show the "Internet explorer cannot display the webpage". Not the one when you mistype an URL and get bounced, but the one you get when you have no internet connect.
This problem as I was told only happens once every 2 months give and take, so I have back-logged it for the passed couple of months for they have tons of other issue from years of neglect. However, starting about a month ago, the frequency seems to be increasing. The last time I restarted the system, it only lasted 3 days. So I googled, strangely, I seem to be the only one with this weird problem and all the usual suggestions and my usual trick did not work (restart IIS, attendant, etc) on remediating. However, when I bumped into SMTP virtual server properties and manually selected the only listed option from the drop down box (internal 192.168.190.7 - exchange box) from the standard <unassigned>. Webmail sprung to life. After scratching my head for about 10 seconds, I let it go and made a note to get aback to this later. Well, after 8 days it just failed again last night.
My intuition tells me that it must be a DNS issue since it's showing "page cannot be displayed error" & but I just cant seem to wrap my head about what would cause this sort of DNS (if that's what it is) error when it has been working flawlessly for an extended period of time.
I had W3C log enabled under SMTP virtual server properties but to my dismay, the log files were a quite incoherent and did not specific much troubleshooting worth info at all.
My biggest problem is, there seems to be zero discrepancy between the time when OWA is working and when its not. Event view shows absolutely no error whatsoever, and I have spent hours looking thru everything during when OWA and work and when it's not, everything seems to be identical.
For the exchange guru out here, could you please lay down a skeleton plan for me as to how to go about attaching this problem?
For the meanwhile, I think I am going to order a exchange 03 book and read up on OWA.
