Solve "HTTP 500 internal server error" and "database connection error" when running ASP. Check the database parameter settings in the conn. asp file ." Problem
After N long attempts, we finally solved the problem that WINXP cannot run. asp .....
1. "HTTP 500 internal server error" occurs when you run ASP"
The main cause of this problem is Ms DTC startup failure,
Solution:
[1]: Check whether your DTC service (full name: Distributed Transaction Coordinator) can be started normally. If it is normal, skip this step. If an error occurs, it cannot be started normally, run MSDTC-resetlog in the Start menu to create a log file. Restart the machine and check whether IIS can be used normally. If not, continue.
[2]: run the following command in cmd:
Cd % WINDIR % \ system32 \ inetsrv
Rundll32 wamreg. dll, createiispackage
Regsvr32 asptxn. dll
After restarting the machine, my problem can be solved perfectly in this step!

Solution: Delete WINDOWS \ Temp and create another temp. Go to Windows immediately and set the Security Attribute of temp (the "Security" attribute option will appear only after you remove the "tools-" Folder Options-"View-" use simple file sharing "check box ), set users to have write permission. OK. The problem is solved immediately.
