Testing with IW http.sys freezes Windows - Joao Lira - 02-08-2020 Hello, I am testing IW with "http.sys" as a server, and for this, I converted an Indy IW server functional application to 'http.sys' according to this page. The application compiles ok, I set it to run as administrative local, it shows up normally, but when I open a web page with any browser in the application page it loads nothing and after a few seconds it freezes Windows 10 completely. After a while, it goes to Windows 10 blue screen and shows as stopping code "DPC_WATCHDOG_VIOLATION". I thought it could be something not properly set in my application, so I try running the 'HttpSysDemo' application too, but it behaves the same way, freezing the computer after a few seconds. I tried disabling the antivirus too but to no avail. I tried the conversion using the latest IW version. What could cause this problem? Regards, Joao Lira. RE: Testing with IW http.sys freezes Windows - SorenJensen - 02-08-2020 Hi Joao Lira, I experienced something similar the first times I tried my HTTP.SYS application. My application used a ado dbcoonnection and adoquery to retrieve data from a sql database on a sql server. My problem was solved when I created a username with which the application could logon on as a service (service start logon) AND I allowed the same user to access the database. Local system was not sufficient, even though the windows logged-on user was admin. Regards Soren RE: Testing with IW http.sys freezes Windows - Joao Lira - 02-09-2020 Hello Soren, I'll try your suggestion, thank you! Regards, Joao Lira. RE: Testing with IW http.sys freezes Windows - Alexandre Machado - 02-12-2020 Are you sure your machine is OK? I've tested uncountable Http.sys applications on several machines, physical and virtual. Not a single issue like that. |
