A Node manager obtains the Windows' computer name and resolve it in
Internet ways (LMHOSTS, DNS and ...) when the Node Manager contacts
Service Managers.  We have to set Windows' computer name carefully as
it can be resolved.

Is this correct?

I found this when I tried to construct a multi-machine node.
A single-machine node does not suffer this problem.

I also faced the time synch problem.
A GSI connection could not be established if not synchronized.

I cound not find any indication in the log files when I used AGTk
2.1.1b and 2.1.2.  The log files said only like `could not establish'
and it was hard to distinguish the cause.
