Hello,

I have three computers (all hp): a netbook running 32-bit Windows 7 starter, a laptop running 64-bit windows 7 premium and a desktop recently upgraded to 64-bit windows 7 premium. The desktop was previously running vista, and the network worked fine under vista.

However, since the upgrade, the netbook and laptop cannot see the desktop on the network or homegroup, or access its files. The netbook and laptop can see each other's files, and the desktop can see the netbook and laptop's files. Also, iTunes can connect to the desktop's library from the netbook and laptop to play music. All three run Comodo antivirus, though none have the firewall enabled. I also disabled windows firewall for a time to see if that was the issue, to no avail. The permissions are the same on all three computers as well.

The computers can ping one another by IP address. The desktop can also ping both computers by name, though they cannot ping the desktop by name. I ran the Homegroup wizard to create the Homegroup, and it is created. All three are part of the Homegroup. I have run Homegroup and Network troubleshooter several times. The Network troubleshooter said it may be a firewall issue, but I set the firewall to allow all IP addresses in a certain range. Unless I did that wrong?

I have been trying to fix this for two days, and cannot find an answer anywhere. I would really appreciate any help.

Here is the ipconfig/all data:

Sure sounds like a firewall on the desktop. What, if any, non-Windows firewall or security suite do you have on it?

As an aside, that's a really strange DNS search list: "DNS Suffix Search List. . . . . . : 24.29.103.16." Do all the computers get that?

I have Comodo on all three computers, but the firewall is disabled. They all use the windows firewall that came with windows 7.

As for the DNS Suffix Search List, yes, all the computers say that ipconfig/all.

Never trust "disabled" firewalls. Often they must be properly configured or completely and cleanly uninstalled.

So how should I configure my firewalls? I figure Comodo shouldn't be a problem, because all three have it, but could it be causing a problem specific to only this machine?

Sorry, but I am not very good with computers, and don't have much experience reconfiguring firewalls.

Sorry to sound trite, but for whatever access is desired. When/if a firewall gets corrupted it doesn't matter how you configure, 'cause it won't work right. The only way to recover from that situation is to uninstall, use the Removal Tool if one is provided, and then reinstall after testing. I know nothing at all about Comodo.

Thank you very much. I uninstalled Norton, because it was leftover from Vista, and the netbook and laptop could see and access the files on the desktop.
