I have an asp.net website install as virtual directory in IIS on Windows server 2003 service pack 2. But, I often found that the website is not working and it occur an error like 'mycustompage.htm?aspxerrorpath=/...aspx ' on address bar and show error on file web.config or sometime on file golbal.asax. After I edit the file web.config or global.asax , it become working again. I noticed if just have many user come to visit this website, it will go bad again.
Any body has experience like this please share to me will be thankful.
