If above solution does not work another solution

It works perfectly fine if you install the same in following order

1. IIS
2. .net
3. Win XP SP2

Reason for the Error:-

If IIS gets installed after SP2, IIS does not server ASP or ASP.net pages. But IIS responds to plain HTML pages.

IIS depends upon COM+. And COM+ depends upon MSTDC (Distributed Transaction Server).

The reason for the error is MSTDC and COM+ link got corrupted and cannot contact MSDTC

Solution:-

We need to

1. re-install MSDTC
2. Create IIS packages (optional, sometimes it works fine without doing this)

Solution:-

1. Login as administrator account.
2. Create a System Restore point (start->programs->accessories->system tools->system restore)
3. make sure that local user accounts IUSR_MYSHECXXXXXD, IWAM_MYSHECXXXXXD are not locked/disabled
4. click on start -> run type "services.msc"
5. Stop and disable the following services

COM+ event system

COM+ System Application

6. Closer services MMC and restart the machine.
7. Open command prompt type the command %WINDIR%\System32\msdtc.exe –uninstall
8. Open Registry Editor and then remove the following keys if they exist:

HKEY_CLASSES_ROOT\CID
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSDTC
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\MSDTC
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\MSDTC

8. Open command Prompt and type %WINDIR%\System32\msdtc.exe –install
9. Once this task is performed properly, start the service COM+ event System as automatic
10. Open registry editor and create a registry key (NOT A VALUE)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\XADLL

12. Type the following command in Command prompt

regsvr32 mtxoci.dll

13. You will receive a message that DllRegisterServer in Mtxoci.dll succeeded.. Click Ok and Restart the machine.
14. Login as administrator account and type the command in Command prompt %WINDIR%\System32\msdtc.exe –resetlog
15. Open control panel->administrative tools->component services.
16. Double click on component services , expand to component services->computers->my computer ->COM+ Applications
17. You should be able to expand all the nodes in this window without any errors. If in case you get errors follow the below steps , else restart IIS with "iisrest" command and reboot the machine and check for http://localhost/
18. If COM+ navigator throws errors, open command prompt and type the following commands

Cd %windir%\system32\inetsrv

rundll32 wamreg.dll, CreateIISPackage

regsvr32 asptxn.dll

19. Then restart IIS( you can use "IISReset" command in command prompt)
