Event Id1088
SourceASP.NET 1.1.4322.0
DescriptionFailed to execute request because the App-Domain could not be created. Error: 0x8013150a
Event InformationHere is an information from news group post:
1) "Ive managed to determine that the error will go away if I switch IIS6 to its default process isolation scheme (it had been set to IIS5 compatibility.) However, it seems I ran into a slightly worse situation: the problem still existed ("Server Application Unavailable" when trying to access any .aspx page), but I was not getting any errors in the event log now. Finally I reinstalled Win2k3 and the problem was fixed".
2) This is a NTFS permission issue. ASP.NET Web applications usually run using the built-in ASPNET account, but occasionally default access permissions are lost. Verify minimum needed permission for ASPNET account to run applications. Refer to section 2 and 3 of Building Secure ASP.NET Applications document.
