Ok I have a bit of a mess on my hands. I will try to document my progress as best I can.
Everything has been 100% fine up until 4/18 when Update Rollup 10 for Exchange Server 2007 SP1 (KB981407) was installed automatically and the server rebooted.
I uninstalled this update...rebooted. Nothing. IIS Admin service, www service and various other services that depend on "HTTP" don't start.
So then I uninstalled IIS thinking I could reinstall. Well now I can't even install IIS or remove the CAS role. Also other services that depend on "HTTP" such as the Print Spooler service still don't start.
I can try to provide more info it can help. I do see a couple interesting events in the logs but nothing that's helped me solve the problem. Exchange is still working fine... emails are going in and out but OWA is completely toast.
Process MSExchangeFDS.exe (PID=2784). Failed to read property Path from metabase object IIS://ironside1.wvca.us/W3SVC/1/ROOT/OAB. OAB synchronization suspended.
Actually that's it right now.... I have cleared the logs so many times I don't really have much now :(
