Symptom
NFuse, Web Interface, and MetaFrame Secure Access Manager loop on the authentication page when using Internet Explorer.
If you are installing Web Interface 3.0 you will see the following dialogue box if your web server name contains special characters.
Cause
An underscore is being used in the Server name and/or domain name of the Fully Qualified Domain Name (FQDN) used in the Universal Resource Locator (URL) address.
For example:
http(s)://mycomputer_1/
— or —
http(s)://mycomputer.my_domain_site.com/
— or —
http(s)://mycomputer_1.mydomainsite.com/
Web server names are not allowed to contain underscore characters according to RFC1738:
host
The fully qualified domain name of a network host, or its IP address as a set of four decimal digit groups separated by ".". Fully qualified domain names take the form as described in Section 3.5 of RFC 1034 [13] and Section 2.1 of RFC 1123 [5]: a sequence of domain labels separated by ".", each domain label starting and ending with an alphanumerical character and possibly also containing "-" characters. The rightmost domain label will never start with a digit, though, which syntactically distinguishes all domain names from the IP addresses.
When JavaScript code attempts to set a cookie on the client browser, the cookie will fail when the server name contains an underscore. So a Web InterFace server with an underscore character will produce behavior similar to what happens when a client has cookies disabled
Resolutions
• Rename the server and/or domain but use alphanumeric characters only.
• Browse to the server by using the Internet Protocol (IP) address.
• This behavior is by design for Internet Explorer. Reference Microsoft TechNet Q316112 for further details.
• Enable cookies.
• Edit the host file for the computer where you are attempting to access the Web Interface server from and create a NetBIOS name without any underscores. (systemroot/system32/drivers/etc/host)
Example – this is just an example so the name and IP address will be different for each environment.
