Sharing refuses to work anymore



I have 2 systems running XP Pro. I did have a working network, for file
sharing, but havnt used it
for file sharing for a while. 1 system is a desktop, the other a laptop.
Both can access the internet fine,
with no issues. Tried accessing the printer from the laptop this week, and
found all file sharing had failed!!
I have tried everything I can think of, uninstalled ZoneAlarm, checked the
net guest account is active, Checked in the group
policy editor, that the guest account can access the network, and is not a
member of the deny network access, although the guest account
is in the deny logon locally, but every time I disable this, the guest
account itself becomes active.
Both PCs have static IPs, and both can ping the router, but not each other.
The laptop is wireless to the router,
the desktop is connected via homeplugs to the router. The previous setup
that worked, was both systems were wireless
but I have moved the desktop to the attic room, and wireless was a bit iffy.
Occ I can connect to the laptop from
the desktop, mainly when the laptop is on, but no-one logged on. It seems
that as soon as I login to the laptop
all filesharing and networking failed. Desktop is never accessable anymore.
Same username and password
on both PCs. Even resorted to using the home networking wizard, to see if
that would resert any iffy
network settings, but no joy. I am really stumped now, and unsure as to
where to go next. It used to work with no setup needed
at all really. Can anyone offer advice.

We need more information to help. Can you ping each other? Have you create
the same username on both computers? Or this search result may help.

Take the desktop back to the room with the Router connect with regular cable
reset the sharing and set them again to working level.
When it works try the Home plug if it acts out again then you should a
different type of Home Plug.
In general.
Make sure that the Software Firewall on each computer allows free local
traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should
be Off, and the active Firewall has to adjusted to your Network IP numbers
on what is some time called the Trusted Zone (consult your 3rd Party
Firewall instructions.
General example,
Vista File and Printer Sharing-
Windows XP File Sharing -;en-us;304040;en-us;304040
Printer Sharing XP -
Windows Native Firewall setting for Sharing XP -
Windows XP patch for Sharing with Vista (Not need for XP-SP3) -
