I have a network with XP-Pro running on 2 PC's & 2 DELL
Laptops & 1 PC running Windows 98SE (5 Total).

All are hardwired to a BEFSR41 Router to the Internet,
High Speed Cable. All have Internet access using IE 6.0.

All machines have shares and are running Simple File
Sharing (except the 98SE which just has shares with r/w
access)

One of the DELL Laptops is a problem.

All other machines can see each other and have access
based on the file sharing permissions granted to each
share. (some r/o some r/w).

All machines can Ping one-another.

The problem DELL Laptop can see all shares on all of the
other machines, and has access to them based on the
permissions granted.

ALL of the machines can see the offending Laptop (Tom-
craig). With the error messages:

All XP-Pro machines return the error:
\\Tom-craig is not accessible. You might not have
permission to use this network resource. Contact the
administrator of this server to find out if you have
access permissions. Access is denied.

The Windows 98SE machine's error is :
\\TOM-CRAIG is not accessible. No permission to access
resource.

ON THE OFFENDING MACHINE:

I have, within system devices removed the NIC, a built-in
3COM 3C905C-TX, and re-installed it several times.
(Driver 4.15.0.0, 10/30/2001)

The firewall is turned off. File & printer sharing is
enabled. The firewall has been enabled/disabled several
times & is currently disabled. File & Print Sharing has
been shutoff & turned on several times & is currently
enabled.

This Laptop is using only TCPIP (as are all other PC's) &
is getting the IP address using DHCP. IPCONFIG shows
that this Laptop is in 192.168.1.XX range used by the
other PC's in the network & is in the same workgroup,
MSHOME. The default gateway address being used is
192.168.1.1 on all machines. The subnet mask is
255.255.255.0 on all machines.

In the TCP/IP settings, within options, all TCP/IP
filtering is "PERMIT ALL".

Comparing the Services running on the offending Laptop to
the other Laptop & the other PC's there seems to be a
discrepancy in the LOG ON tab in the SERVICE "Distributed
Transaction Coordinator". All other machines are running
LOG ON AS: This Account: "NT AUTHORITY\NetworkService"
with some invisible/starred out password.

The Offending machine for this service is LOG ON
AS: "Local System Account".

When I try to change to "NT AUTHORITY\NetworkService" for
this service I need to change the password too, because I
get the dialog box "Please enter a valid password". When
I try to change the password to the administrator's
account password, I get the error "The account name is
invalid or does not exist, or the password is invalid for
the account name specified.

I'm not sure that this SERVICE is the problem but I can't
find anything else. I have used ADAWARE SE & SPYBOT to
remove spyware and Norton Antivirus 2003 is running and
up to date with Virus Definitions and scanning.

HELP... Please !!!
