your suggestion is correct but now I've got this strange problem.

When I use my asp page (try.asp) to access the text file by this url
http://IIS_WebServerName/try.asp, it is all right, but when I use this url
http://IIS_WebServerName.DomainName.Ext/try.asp , I obtain the usual error:
my asp page can't access the text file.

Can you still help me?
