[cobalt-users] [550] Some vsites will not resolve

["Salzer, Tom" <tsal461@xxxxxxxxxx>]

Looking for some ideas on what the problem may be and how to fix.

I'm migrating two dozen vsites from a RaQ XTR to a 550. Used cmuImport -d
successfully to bring the CMU archives into the 550. I'm currently testing
the migration on our private LAN, so I've added each vsite URL to my Windows
hosts file. 

This has worked well except for three vsites. When I test them in my
browser, I get a download popup (Open, Save, Cancel, yadda yadda). The file
name is index.html and the vsite URL is correct. But the index.html page
doesn't automatically open in my browser. If I select Open it looks fine.

Here's what I've checked to date, but the problem remains.  
[1] No custom .htaccess files in the three offending vsites, in fact,
nothing special at all.
[2] Each site is set to the same IP and autoDNS is enabled for each vsite.
[3] Compared the site files in /etc/httpd/conf/vhosts and they are identical
(except for the URL).
[4] Have gone through httpd.conf, srm.conf and access.conf and saw nothing
unusual.
[5] File and directory permissions are the same on vsites that work compared
to vsites that don't work.
[6] Have suspended all sites and tried unsuspending just one that didn't
work, but no joy.
[7] Double checked my hosts file to make sure I'm pointing to our internal
IP for testing, and all is well there.
[8] Reimported the vsite with cmuImport. 
[9] Deleted the entire vsite and users using the 550 GUI, then reimported
with cmuImport.
[10] Deleted the entire vsite and users, then created it anew, SCP'd the
vsite files in.
[11] Examined primary services under Network Services, DNS and found
duplicate entries (the real IP address and dupes using the LAN IP). Deleted
all entries with the real IP address to avoid redirection confusion.
[12] Created a brand new vsite through the GUI and it exhibits the same
problem.  The only file in it is the default index.html.

To me, this points to Apache or DNS or both, but I've been at this more than
a week and still do not see how to fix this.

P.S.: Perhaps this will prove helpful. When I execute /etc/rc.d/init.d/httpd
restart, I get a bunch of identical lines saying "[warn] NameVirtualHost
165.151.31.13:80 has no VirtualHosts"
