Hi

I am unable to access certain PCs on my P2P network - worked fine until v.
recently. I can see some of them but not others. I have uninstalled ZoneAlarm
and turned off Windows Firewall. All PCs running Windows XP SP2 - variations
of Pro, Home and Tablet. All updates available applied.

I can see the workgroup (Happyatom) on both but on one PC I cannot see any
PCs and when clicking on the workgroup icon I get the message "Happyatom is
not accessible. You might not have permission to use this network resource
...." On the other I can see the PCs in the workgroup but get a similar
message when clicking on their icons.

If I type the IP address of either PC on the other, then I can access the
shared drives. (I log into all PCs with the same username and password). All
PCs can access the internet through a hub and router.

The browser service is enabled on all PCs and I have enabled NetBIOS over
TCP/IP. The problem PCs are all in the same workgroup. Having researched as
much as I can I am still no nearer sorting out the problem. I would be very
grateful for any help.

Below are the results of running diagnostics on each of the problem PCs.

Many thanks in anticipation for any assistance.

Paul

This looks like a knock on effect from ZoneAlarm. Your computers are unable
to find the master browser for the workgroup and thus unable to reference
what computers are and are not in the workgroup.

Try changing the work group name for all the computers to something new.
Also I know there is a samba command to query the master browser so there
must be a windows alternative. Have a look at that for your answer. Someone
here will know in more detail.

Thanks for your reply. Unfortunately I have been down the ZA route -
unistalled and then deleted all files following guidelines on ZoneAlarm
website. Also I would have thought that ZA would have prevented me seeing the
disks on the other PC when I type in the IP address - but using the IP
address I have full access to the other PC.

As regards master browser - using BROWSTAT, one PC returns itself as the
master browser, the other is unable to determine the master browser - using
GetAdapterStatus switch.

It has to be something that zone alarm leaves in as with it being unable to
find the UNC as you say it shows that your computers are not correcting
electing a master-browser.
Apparently it can take up to 15min for a computer to appear in a workgroup
but from what you have said I suspect you have tried waiting that long.

With a network that small you could manually set the ip's and enter them
along with the hostnames in the host file and eliminate the discovery delay.

I have to admit that ZA is top of the list of culprits - but I have removed
every trace of it as far as I know, following Zonelabs instructions.

My network is slightly bigger - there are 9 PCs on it. I would prefer not to
have static IPs as work colleagues sometimes bring their laptops and it is
easier not to have to keep worrying about settings and just have the router
DHCP allocate them.

I suspect I will probably return to a backup from a couple of weeks ago when
everything worked OK as I have already 'wasted' several days on this.

Many thanks for your help devstuff!
