?? Question 1:
There are two XP computer
A computer (DN1) IP: 192.168.15.108
B computer (DN2) IP: 192.168.15.110 (have a printer, have Shared)

Two computers are joined the domain, it had closed firewall

Now encountered this kind of situation, A computer can't connect B printer, between A computer and B computer cannot PING, computer can PING A and B and C can also connect A printer, A, B can PING C computer,

But, again, the cancellation of B computer, computer A and computer B can PING each other, the printer is normal, but again, after more than 10 minutes (not sure) appeared problem, AB computer cannot PING each other, again cancel B computer can
Can you tell me how to solve? (don't want to reinstall the system, and other computer also is such)



Question 2:

A computer (DN1) IP: 192.168.7.10
B computer (DN2) IP: 192.168.7.110

Two computers are joined the domain, it had closed firewall

Now encountered this kind of situation,
A computer can't PING B computer,
Computers can PNG through A computer, B
Computer can PING A and B, C
Type A, B, computer can PING C, but A computer can't PINGB
Can you tell me how to solve? (don't want to reinstall the system, and other computer also is such)

Can try A and B is added in the domain controller computer host, if still won't do in the A and B machines on the host file to add the other machine's IP and full name forced A and B machine recognize each other,

Yes, use the Administrator login, to... \ Windows \ System32 \ drivers \ etc path to find the host file, fill in the IP and computer name save, and then try to identify whether can find ping way,

Still won't do, where is the problem I do not know what a logout PIng again and can, over a period of time and no,

A, analytical problem, careful observation and contrast the MAC address of ARP resolution consistent?
Such as AB can ping C, AC cannot ping, ping A B in both A and C, respectively, and then use arp - A command to see two computers under B IP and MAC address is consistent?
If not consistent, can consider the ARP deception,
Two, interpolation, insert fault computer cable pulling repeatedly see ping result,
Three, returned to normal after cancellation, seems to be related to a process, need careful contrast tests repeatedly to find out why,

Don't need to add the HOST record

Haven't solve? But there is a change after the IP (IP until there is no conflict), didn't listen to his colleagues feedback, don't know why he didn't want to trouble or

A, C pingB computer's MAC is consistent, is A problem, then the cancellation, A and B is normal, but the later is between A and B can, at present there is A change after the IP (IP until there is no conflict), just didn't listen to his colleagues feedback even not, now this A few I also change the IP test under
