Debug ASP program, you may use IIS, don't you know that you have encountered this situation?
When you start IIS, you cannot pop up the IIS interface, but you will pop up the inexplicable saving as "* .msc" file dialog box when shutdown or log out. When you start a few times, there will be several such dialogs (my system is Windows2000 IIS5.0).
I have encountered this situation many times, because I can't find the reason, I have to reload the system. Recently, I have encountered this situation. I suspect that it is because of the conflict caused by software, so I decided to uninstall the software in the machine (it is not a lot of software installed in the machine). I found that when Norton Server Edition 8.1 and Norton personal firewall 5.0, IIS can be used normally. What is even more strange is that I will put Norton, IIS is still available.
So I think Norton may cause IIS to use normally in some cases, but this phenomenon is more concealed. Because, it is not an unable to use Norton IIS, but not necessarily in that case. This is the case, Norton is installed for a few days, IIS has always running normally, but IIS suddenly can't use it.
If you have encountered this situation, I hope this article can give you a reference.
I have encountered this situation recently: System: Windows 2000 Professional SP2, only installed Norton personal firewall 5.0, IIS can be used because Net, installing SP4, found that IIS can not be used, in order to confirm the problem, I unloaded the Norton personal firewall, found that IIS can be used normally, then install the Norton personal firewall, IIS is not ok, it is possible after uninstallation. I modified the Rising firewall, did not find an IIS above the problem.
I think it may be a problem that IIS cannot be used in Windows 2000 Professional SP4 Norton Personal Firewall 5.0. But Windows Server may have no such problem.
