add/edit application extension mapping ok button is grayed out
Sunday, February 4th, 2007If you are trying to map a new file extension in IIS 5.0, you may notice that the OK button is grayed out and that you cannot select it, and therefore you cannot add a new file extension mapping. There may be two reasons for this:
1) You may be trying to add a new extension mapping at the directory level and adding a * to the extension as in *.newxt - don’t do that. IIS 5.0 won’t tell you why it’s not letting you add the extension (IIS 6.0 will). Just remove the * and add .newxt where newxt is the name of your extension.
2) You have encountered a Windows XP User Interface bug. The button should not be grayed out it’s a well known bug. Just click the first textbox or click around the dialog and the ‘Ok” button should become active.
