I posted the threat 6-7 months back and then gave up doing networking as the problem persist. Now i have formatted the hard drives of both systems and i was hoping that the networking will work fine because settings are default on both computers but unfortunately it did not happen.
This is my case. Im using two P4 computers named AAA and SSS. Both have lancard and they are connected via router for a single internet connection which works for one pc at a time. I tried to connect both PCs for file sharing but could not do it. I gave AAA ip: 192.168.0.1 and SSS 192.168.0.2. Subnet mask was 255.255.255.0. I also tried giving the primary dns same as the ip address of first (AAA) computer but it did not work. Whats happening here is that SSS can see AAA but cannot access it this error pops up "MSHOME not reachable. You may not have permission to access............" but AAA cannot even open the workgroup. when i click "View Workgroup Computers" it gives me the above mentioned error. Interesting point is that symptoms of both computers are different although they both have new windows XP installed on them with the same CD and both have service pack 2. I have installed Avast Antivirus on both systems and i think it may be the root cause of the problem but still cant be sure and ofcourse dont know how to get out of it

File sharing is on, netbios over tcp IP enabled, firewall "off" on both PCS and workgroups are also same "mshome". Both PCs can ping each other. SSS can see itself and AAA but it cannot access. AAA cannot even open the workgroup folder. I am sure that there is no hardware conflict bcz i have shared files b4 on these two computers without hardware change.

I have also tried the following:
1. gave admin right to all by giving command in cmd
net localgroup "Administrators" "NT Authority/Local Service" /add
Command was successfully entered in both PCs but nothing happened

2. Checked the value of
HKEY_LOCAL_MACHINE\SYSTEM\CurrentContr... l\Lsa
DWORD KEY "restrictanonymous" = 0
its zero on both PCs

3. Added a registry Entry named "IRPSTACKSIZE" and changed the decimal value to 15 on both PCs but again useless.

I have run the networking wizard on both machines numerous times. My intention is not to share internet on both machines but i wanna share files between them.

Please please please do help me.

Regards,

Ali
