Well, it's been a totally frustrating day.

The desktop can ping the laptop by name which gets translated to the 
correct address and all 3 trials are successful.
The laptop can ping the desktop by name, which gets translated to the 
correct address but the ping is not successful.  It times out on all 3 
trials.  Yet we know that both machines have internet connectivity 
through the router since the internet is working fine.

running "netstat -n" on each machine returns only information about 
itself.  Likewise, "route print" run on the laptop returns only 
information about itself and the router, nothing about the desktop where 
the printers are installed.  I uninstalled several old print drivers 
from the laptop and then tried printing to the HP inkjet that's on the 
desktop and has always worked previously... no go.  The document failed 
to print and ended up stuck in the laptop's HP printer queue.

Running "arp -a" from each machine properly resolves the router's MAC 
address.  Running "ipconfig /all" is similar to "route print".  Each 
machine returns only the info for itself and the router, nothing about 
it's network partner.

If I then attempt something like mapping a drive from each machine I get 
failures on both but subtly different messages.  The laptop says: "The 
drive could not be mapped because no network was found."  The desktop 
says: "The network path xxxxxxxxxxxx could not be found."  Remembering 
that the desktop could ping the laptop but not vice-versa putting these 
data points together is perhaps a clue to what's happening or not happening.

There have been no password changes on either machine for many months, 
long before they were disconnected and rejoined.  I checked the local 
net security policy or tried to.  The desktop supports viewing and 
changing such policies through the control panel's administrative tools 
or via the command line "gpedit.msc".  These are set for guest access as 
they have always been.  But the laptop has no such tools in the 
administrative tool set and also doesn't support "gpedit.msc".  Both 
machines are on Service Pack 3 but the desktop runs "Media Center 
Edition" and the laptop runs "Home Edition".  I assume MS didn't want 
home users messing with network security policy.  Presumably the 
settings there are as they have always been since there's no ready way 
to change them.  But I do suppose that the QM2's IT personnel could have 
done so.  But I don't know why they would.

Given that things can pass in and out of the router to the internet but 
apparently not between the local machines is it reasonable to suspect a 
partial failure of the router?  I did repower and reboot it after I came 
home.  Maybe I should to that again as well as swapping cables between 
its ports?
