IIS7 ASP default upload file only set to 200kb!!!! Yes, there is true. Now a days, even one image is larger then that. It not a pratical way to leave as 200kb upload for ASP, so below is the method to increase it.
(1) Lauch IIS ( Windows 2008: Go into Administrative tools > server Manager > expand Roles > expand Webserver > click on IIS)
(2) click on the ASP icon
(3) Increase the maxRequestEntityAllowed , the number unit is based on bits.
(4) Increase it and apply it. Done.
short cut, run the command line as below
appcmd set config /section:asp /maxRequestEntityAllowed:104857600
NOTE: The extending of this value may increase the window for DDOS attack
