Problem

You may encounter the following problems if you are working with Cisco CallManager 3.x installed on a server that has a special character (such as an underscore) in its hostname, or MS Internet Explorer 5.5 with SP2 and a Q313675 patch or above.

• When you conduct a basic search and hit submit, the page returns the same page.

• When you try to insert a new user, this error message appears:

  The following error occurred while trying to execute the command.
  Sorry, your session object has timed out.
  Click here to Begin a New Search

• When you try to update the CallManager user, this error message appears:

  Either the current session has expired, or access has been
  denied because of insufficient privileges. Please close the 
  current window and open a new one.

Solution

You might not be able to add a user or do a search on the Cisco CallManager Admin user pages, if your CallManager hostname contains any special characters such as, underscore or period (for example, Call_Manager). Domain Name System (DNS)-supported characters include all letters (A-Z, a-z), numbers (0-9), and hyphen (-) and any special characters are not allowed. If the Q313675 patch is installed on your browser, make sure that the URL does not contain any non-DNS supported characters.

For more information about the Q313675 patch, refer to MS01-058: File Vulnerability Patch for Internet Explorer 5.5 and Internet Explorer 6 .

To resolve this problem, you have these options:

• Access the Cisco CallManager Admin pages using the IP address of the server.

• Do not use non-DNS characters in the Server Name.

• Use the localhost or IP address in the URL.
