My problem is with a XML file that resides on my windows 2003 web server.
I have this user control which I include on every page in my applicaiton.
The control makes it possible for the users to leave feedback when using the page.
The feedback is written to a XML file which I have put in a folder "C:/Save/".
I've set the access rights on this folder so that the "IUSR_MachineName" has full rights on this folder and it's children.
The "c:/save" folder is included as a virutal folder in the application i.e. /webApplciation/save
All this works fine. The coments are saved along with some other information from server variables.
I've tested and I can both leave a comment and read the given comments in the xml file.
The problem is when I've left the computer running for a while the XML file mysteriously disappears.
Any ideas? I wonder if this is due to some sequrity settings ont win2003 server that I'm not avare of?
I've included the control code and XML file below.
cheers,
mortb
