Details

If I set up Mozilla to launch both a browser window and the Mail/News client
when the broadband Internet is down, the browser is unable to reach any local
web servers.

Mozilla 1.1

Mozilla/5.0 (X11; U; OpenVMS COMPAQ_AlphaServer_DS10_466_MHz; en-US; rv:1.1)
Gecko/20020828
How are you specifying your local servers, by name or by address. If by name,
what (or rather where) is you DNS host?
Status: UNCONFIRMED → ASSIGNED
Ever confirmed: true
Also, do you have a proxy server defined?
The TCPIP database only contains the hosts on the local LAN.  The Name service
is pointed at the ISP's DNS.

There is no proxy server.

John,

Sorry I haven't gotten back to you on this one. It is not assigned to me and it
slipped through the cracks.

Is this still a problem on Mozilla 1.3? If so, can you provide more info? For
example, could the mail part of Mozilla be blocked on a DNS lookup (I think this
will also block other threads doing name lookups)? Are you trying to access the
local web server by name of ip address? Can you ping the local web server
successfully? 
I will try to test this soon.

The mail part of Mozilla could very well be blocked on a DNS lookup.

My configuration is that I have a local TCPIP DNS server that queries the ISP
DNS if it can not resolve the name.  The TCPIP BIND server caches entries, so I
do not know if it needed to do a DNS lookup or not.

The local web server is looked up from the TCPIP$HOST file, and is usually
invoked by name.  There is no problem pinging the local web server.  It is the
administrative interface to my firewall.
Still a problem? One thing I fixed recently for OpenVMS was to put a lock around
the DNS lookups, since on OpenVMS these routines are not reentrant. Not sure
exactly when this fix first saw the light of day, but its in 1.4 beta for sure.
Via email John reports: The case where starting e-mail and the browser both at
startup with no internet connection does appear to have been fixed.

Closing bug report.
