Sharing & "Entire Network" ??

I have an XP pro system cabled to a wireless router that's cabled to a cable
modem.
I have an XP home system connected to the router via wireless.
The XP home system was just added a couple of weeks ago. At that time I
installed a brand new USB wireless adapter to it.
I ran the Network Setup Wizard on the pro system and then on the home
system, setting up a network named 'HOME'. All (Internet access, printer
sharing, folder sharing) worked just fine until a couple of days ago.
Now - on either system - when I go to My Network Places | Entire Network |
Microsoft Windows Network the system(s) take about 30 seconds to find the
'HOME' network. When I click on that Icon the systems takes about 45second
and then times-out to an error message "HOME is not accessible. You might
not have permission to use this network. . . . "
I still have Internet access, shared printers still work such, shared
folders are usable if I add then using Add Network Places. However, In
addition to the above mentioned 'Entire Network' issue my Shared Documents
folder(s) refuse to be added as Network Places.

Windows firewalls are disabled on both boxes. At the suggestion of another
newsgroup I added identically named user admin accounts to both systems. (I
was told this is "required" - but it was not required back when the above
items were working)

The solution to this is not critical since I do have print sharing and do
have 'regular' folder sharing.

Up until a few days ago I could just click on my "HOME" network Icon and the
entire shared network was visable. Not now!

Any help/suggestions is appreciated.
