Can not ping Host machine on my network

[corrie]

Hello all

This is an attempt to sort out a Ping error that I get when I try to ping my host machine from the other 2 Machines on my Network M1 being the host.

My problem is that I can not ping to M1 from M2 or M3 ??? but I can Ping M1 from M1 of course -- I can Ping M2 to M3 or vis versa works .. Ping M1 to M2 or M3 works as well

My set up is M1,M2,M3 M= Machine .. each has XP Home edition installed with Service Pack 2

I cleaned the registry of any left over folder & file locking software that I previously had & re-booted

I have re made my network wizard for each machine giving the workgroup

a different name each time I try to reslove this ( same name for M1,M2+M3 of course ) I have no Norton software installed on M1 at all.

I have NET BIOS Enabled to Default ( Advanced TCP/IP etc WINS folder )

as I have static IP Address's for M1,M2 & M3 ... as thay are on my network and I also login to them remtly from outside my network so they must have static internal ip addresses

but I still can not ping to M1 from M2 or M3 ??? but I can still Ping M1 from M1 of course

I have used the use the netsh command to reset the TCP/IP protocol stack i,e for winsock & interface command.resetlog.tx but this hs not worked I am at a stand still ?? can anybody shed any light on this

node is set to broadcast on all 3 machines .. ipconfig/all

I have made sure the guest accounts have blanks passwords

Windows firewall is disabled, the firewall active is the 2wire HG 1800 ( my router )

any help on this would be very helpfull .. if anything needs more explanation please do not hesitate to ask as I am all ears :0((
