Somehow, I can not access one of our OES2 Linux10sp1 servers with
http://servername or server_ipaddress from my workstation. But I can
access that page from the server itself. The error I got says:"You don't
have permission to access the requested object. It is either
read-protected or not readable by the server.". Can someone advise what
cause this problem?

By the way, I can access iManager of this server by typing
http://servername/nps with no problem.

Any response will be greatly appreciated!!!
