Sering kali, saya mendapatkan pesan error "Server Application Unavailable" ketika pertamakali setup IIS dan ASP.NET di komputer baru. Pesan lengkap dapat dilihat pada paragrap berikut.
Server Application Unavailable
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.
Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.
Setelah dicek di event viewer ternyata aspnet_wp.exe (WinXP) tidak dapat berjalan karena kekurangan hak akses untuk mengakses sumber daya .NET Framework. Untuk mengatasi permasalahan ini sangat sederhana cukup tambahkan group "LocalComputer\Users" dari 3 user berikut ke.
- IWAM_<ComputerName> contoh: AMASYKUR\IWAM_AMASYKUR
- IUSR_<ComputerName> contoh: AMASYKUR\IUSR_AMASYKUR
- ASPNET
Setelah ketiga ketiga user tersebut ditambahkan sebagai member group Users, reset IIS dengan perintah
C:\WINDOWS\system32>iisreset
Attempting stop...
Internet services successfully stopped
Attempting start...
Internet services successfully restarted
Berhasil deh....
