Unable to log in with Internet Explorer – case of the disappearing cookies

Noticed a strange problem where Internet Explorer would not be able to log into SalesLogix, while Firefox had no problem. On IE the user would enter their username / password and be immediately resent to the login screen. Upon investigation with Fiddler we noticed the cookies were not being sent by IE. Even though the server sent them, they would not “stick”.

It turned out, this was caused by the name of the web server “slx_test”. The underscore is not a legal character in a DNS name, even though Windows lets you enter it as a computer name, so IE does not accept cookies with such a domain. Renaming the server slx-test fixed the problem!
