Hi,

I have installaed the standlaone ITS server. When i try to access the ITS server using

http://localhost/scripts/wgate/webgui/! thing work fine.

If i try to access the ITS server using the link

http://hostname/scripts/wgate/webgui/! or

http://ip of hostname/scripts/wgate/webgui/!

an error is thrown up even when i access through the ITS server itself.

The ip and hostname are pinging from every where.
