I have 3 pc's on my home network 2 with XP Pro and 1 with XP home. I
had I no issues then all of a sudden 2 of the PCs can no longer access
each other on the network. PC A can'tconnect to PC B or C. PC B can't
connect to A or C but can access B. PC C cannot connect to A or B. I
get the unable to connect error. I have tried running
the network wizard with no luck. Something has changed. Could it have
been one of the windows updates? I have a friend that is having the same
problem! His desktop can access his laptop but the laptop cannot access
the desktop. This seems to be a big issue right now with XP. (All PC's
mentioned are XP) I have tried the following:
1. Turned off windows firewall
2. Installed Netbeui
3. Network ID.

Please help soon!

Thanks,

Brian

The Network Wizard is a piece of crap and you don't need it with an all NT
based O/S(s).

If, you're behind a NAT router, then leave the XP FW off until you get
things working.

I worked with a guy that had all XP machines using a Linksys router and they
couldn't share resources for some reason. I had basically the same set-up
with XP machines and had no problems using only the TCP/IP protocol as he
did.

He switched to the MS NWlink IPX/SPX Netbios Compatible protocol on all
machines and that worked for him.

The above is what is in the link below.

If you use MS Nwkink, youshould uninstall Netbeui first or you may mess-up
the TCP/IP Stack and it will have to be reset.

So is it 3 PCs not connected to any ISP, not complications caused by
internet access.

>had I no issues then all of a sudden 2 of the PCs can no longer access

A, B and C are helpful as you didn't identify which was XPPro1 , XPPro2
or XPHome

>each other on the network. PC A can'tconnect to PC B or C. PC B can't

By connect it's assumed you mean file shares?

>connect to A or C but can access B. PC C cannot connect to A or B. I

Do some basic checks first,

Have you checked the IP address settings, subnet masks and gateway?

Can you ping to/from any of the PCs to the others?

No warnings / erros in the event logs?

Check accounts / passwords all match.

>the network wizard with no luck. Something has changed. Could it have

Have never used and from past history would avoid using the network
wizard.

From Win 2000 if you (not introducing internet access issues) set the IP
addressing to DHCP , the PCs will automatically configure IP addresses.

>been one of the windows updates? I have a friend that is having the same

If it was Windows updates the uninstall folders are sorted in date/time
so you could try uninstalling updates from the newest until it works
again?

Maybe even review the updates / security patches
www.microsoft.com/security
http://support.microsoft.com/
and see if any have been (yet again modified) updated since thier
release.

Ask in one or two of the MS XP newsgroups, or even Google for the patch
/ update KB article numbers.

Must be XP, as my NT4, XP, Win 2003 x64 Server , 2000 network is still
working fine with all file shares as I havent yet installed the July or
June updates as it's a bit too soon.

Had the same type of problem before. It took me a while and a couple of
headaches to figure it out.

Please keep in mind that unless you are comfortable with editing the
Registry, this should not be attempted. You can really screw up your
system.

It could be an IRPStackSize issue. You should check in the Registry on
one of the unreachable machines to be sure that there is an IRPStackSize
value at
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\LanManServer\Parameters.

Look for the name IRPStackSize in the "Name" column. If it does exist,
check the value. It should be set between 15 and 50. Sometimes this
value can be increased to attain connectivity. I had to set mine at the
maximum on one machine in order to access it.

If there is no IRPStackSize value, right click in the right side of the
Registry Editor. Click New. Click DWORD Value. Rename it
"IRPStackSize". Right click the new value and click MODIFY. Set the
Decimal value at at least 15. Test form the other machine for
connectivity. If still no connectivity. Try increasing the number of
the value a bit at a time, keeping in mind that the maximum value should
be 50.

Please be careful if you are not experienced with Registry editing.

Hope this helps.

It could be as some articles mention network issues related to that
parameter, found some PCs at work this week with this error logged.

However before jumping in with a reg edit and the warnings it would have
been better to tell the OP to check the system event log for that error
message and get the event ID first.

If they aren't getting the error, then there is no need to fix the
registry.

If you do not have a router, get one.
Power off all units (power off is not the same as reboot).
Power on 1 unit, wait 1 min. power on next.

As first responder said, do "ipconfig" on each and post results here.

I have had a Linksys router for 2 years and had no problem. All this
just came about recently. I will try the power off and let you know.
