Problem access CCMAdmin page using hostname?

[chan-kuen.hui]

Dear All,

I have edited the hosts and lmhosts file with hostname and IP address on the server as below:

ccm1 10.1.1.1

When I use http://10.1.1.1/ccmadmin, I can access to the web page.

However, when I use http://ccm1/ccmadmin, I cannot access to the web page and error as shown:

"Problem Report: The system detected an Unresolved Hostname while attempting to resolve the host specified in the requested url."

Thanks.

C.K.

Just to verify, the config in the hosts file should be

10.1.1.1 ccm1

and lmhosts

10.1.1.1 ccm1 #PRE

It appears you may have this backwords. Can you ping ccm1 from a command prompt? Are you using any sort of proxy server? Did you change the hostname of the server?

What response do you get when you ping ccm1 from cmd-prompt of the server? What about a ping from another computer?

Correct the formatting of ip/hostname of the lmhosts and hosts files. Make sure you do not have extensions on these files; it's common to create and save them as txt files.

At a command prompt run:

nbtstat -R

nbtstat -c

You should see ccm1 "mapped" to 10.1.1.1 in the NetBIOS cache table. If not, something in your LMHOST or HOST file is incorrect.

Also, try the LMHOST file without any extension on it. By default it is LMHOSTS.SAM or something like that. Try it without the .SAM.

A further note when editing the hosts file, ensure that you also specify the FQDN for the host. for example:

127.0.0.1 Localhost

10.1.1.1 CCM1 CCM1.mydomainname.com.

Also on the server configuration within CCM, configure the IP address instead of the default DNS hostname, this will remove the dependency on DNS for resolution. Although this should not matter if you have specified you callmanagers with the hosts file for each and every callmanager in you cluster.

Failing to do so may result in SQL replication issues.

Yes, on my hosts and lmhosts file,

10.1.1.1 ccm1

10.1.1.2 ccm2

I can access to ccm2 using http://ccm2/CCMAdmin or http://10.1.1.2/CCMAdmin but for ccm1, only http://10.1.1.1/CCMAdmin and cannot access http://ccm1/CCMAdmin

Also, when ping ccm1, the result is positive.

Right-click anywhere on the web page, select "VIEW SOURCE". Post the results in a text file.

You could also try putting the dns suffix for the fqdn for your server in the DNS suffix search order.
