11001 - Host not found

Internet Security and Acceleration Server



CAUSE
This issue occurs because versions of Microsoft Internet Explorer earlier than version 7 do not support IDNs. IDNs uses non-ASCII characters. Internet Explorer 6 and earlier versions cannot resolve a URL whose domain name contains non-ASCII characters.



RESOLUTION
To resolve this issue, upgrade to Internet Explorer 7. If you are unable or unwilling to upgrade to Internet Explorer 7, you may install a third-party program to support IDNs. For example, the following third-party programs support IDNs:  The Verisign i-Nav plug-in

 The Domain Avenue.com iClient plug-in

 The Netpia NLIA plug-in

MORE INFORMATION
An IDN is a domain name that uses non-ASCII characters. By using IDNs, users and companies can create domain names in their native language. The Internet Engineering Task Force (IETF) published the IDN standard in March 2004. For additional information about IDNs, visit the following Web site to view IETF Request For Comment (RFC) 3490:

http://www.ietf.org/rfc/rfc3490.txt

IDN support was introduced in Internet Explorer 7.
