Map drives between 2 XP SP2 machines...

I am having trouble getting a connection (ping, with eventual desire to map a
drive) between two machines on XP SP2 - before upgrading to XP SP2 I did not
have this problem.

Here's my set up...
Two laptops with XP SP2, connected via a router. When logging into the
"local machine" on both laptops, neither machine can PING the other. Same
story when I login to both machines on the same domain... what gives.

I know the IP addresses of both machines, subnet mask and such - but I can't
reach one machine from the other... I need help - can someone throw me a bone?

Is the Windows firewall enabled? If so, check the firewall exceptions =
to ensure that ICMP Ping/echo packets are allowed. This setting and =
other ICMP settings are found on the Advanced tab, ICMP, Settings.

Thanls for the quick reply!

On the "Windows Firewall" dialog's general tab, both the on and off radio
buttons are greyed out - and there's a message at the bottom stating that the
"Windows Firewall is using your domain settings"... (I'm logged in on the
domain account - the firewall has this same setting when I login to the local
machine)

Regardless, under the exceptions tab, I have no program or service named
like "ICMP Ping/echo packets" - how do I add this exception to the list
(clicking add programs reveals no program like "*ICMP*")? Further, how will I
know whick port(s) to open up without creating a security risk for myself?

Oops, I see that in your message now...

Ok, on both PC's I've got the option "Allow incoming echo request" checked

Is there some port that I need to enable (and how)?

You should be able to do it by IP address, or by machine name. If port =

Pings don't use a port. The ICMP protocol is a network-layer protocol (not a
transport-layer protocol). So a port exception will no affect their
success/failure.

While you're at the command prompt for either PC and type in 'arp -g'. See
if either PC shows the Physical Address of the other system. If not, ensure
your subnet mask are correct and (as Mr. Knox points out) check out some
type of firewall setting.

I am having trouble getting a connection (ping, with eventual desire
to map a
drive) between two machines on XP SP2 - before upgrading to XP SP2 I
did not
have this problem.

Here's my set up...
Two laptops with XP SP2, connected via a router. When logging into
the
"local machine" on both laptops, neither machine can PING the other.
Same
story when I login to both machines on the same domain... what
gives.

I know the IP addresses of both machines, subnet mask and such - but
I can't
reach one machine from the other... I need help - can someone throw
me a bone?

Well, I verifed that I have an ICMP exception for PING/echo and have port 445
open on both machies (with the scope of the exception being my network, i.e.
subnet) - But I still am not able to get an comminucation b/w the machines.

Firewall on/off - now a correction to one of my eariler posts. When
logged into the local machine (i.e. not the domain) for both machines: On
Machine A, on the Firewall's General tab, The "Off..." radio button is
selected, but both the "On..." and "Off..." buttons are disabled (greyed
out). The message at the bottom states that "Windows Firewall is using your
domain settings". On machine B, on the Firewall's General tab, the "Off..."
radio button is selected and enabled. The message at the bottom of the screen
states that "Windows Firewall is using your NON-domain settings". I'm not
sure of this discrepancy is causing an issue.

What other reasons would there be that I can't get these two machines to
talk - given they could communicate before I installed XP SP2?

Ok, one other possible issue - I just realized that I also installed
Checkpoint Software technologies' VPN-1 SecureClient software on both
machines. It looks like it has settings for security profiles but I don't see
a way to set exceptions... could this be the culprit? If so, any ideas on how
to deal with it (other than disabling it...)

Thanks for your help thus far!

On the "Windows Firewall" dialog's general tab, both the on and off radio
buttons are greyed out - and there's a message at the bottom stating that the
"Windows Firewall is using your domain settings"... (I'm logged in on the
domain account - the firewall has this same setting when I login to the local
machine)

Regardless, under the exceptions tab, I have no program or service named
like "ICMP Ping/echo packets" - how do I add this exception to the list
(clicking add programs reveals no program like "*ICMP*")? Further, how will I
know whick port(s) to open up without creating a security risk for myself?

I am having trouble getting a connection (ping, with eventual desire to map a

have this problem.

Here's my set up...
Two laptops with XP SP2, connected via a router. When logging into the
"local machine" on both laptops, neither machine can PING the other. Same
story when I login to both machines on the same domain... what gives.

I know the IP addresses of both machines, subnet mask and such - but I can't
reach one machine from the other... I need help - can someone throw me a bone?

So when I ran 'arp -g' I only got one entry - I think its my router's local
address - regardless, none of the IP's (wired or wireless) for the other
machines (I tried from both) were listed.

Being a novice at this I'll ask stupid question - how do I check my sub-net
mask?(where do I look and what am I looking for?)

Before you respond, you may want to check my other post at the end of the
other thread...

Thanks for your help thus far!

Pings don't use a port. The ICMP protocol is a network-layer protocol (not a
transport-layer protocol). So a port exception will no affect their
success/failure.

While you're at the command prompt for either PC and type in 'arp -g'. See
if either PC shows the Physical Address of the other system. If not, ensure
your subnet mask are correct and (as Mr. Knox points out) check out some
type of firewall setting.

If you have DHCP configured, then your subnet mask is easily obtainable from
the client PC - you'd have to check the DHCP server (or router) and see what
the subnet mask is set to. Unless you have manually changed the TCP/IP
settings, you're probably setup for DHCP...

If you are still experincing issues - you may want to try un-binding the VPN
(or other) software from the network card. Do this by simply unchecking the
VPN componnet in the Properties of the network card - and then click close.
This way, you don't have to uninstall any software just for testing
purposes. To make things really simple (and eliminate any VPN potential
issues), uncheck everything from the network card except the following three
components: 1) Client for Microsoft networks, 2) File and Priner Sharing and
3) Internet protocol TCPIP. (Actually, you can even uncheck File and
Pritner sharing just to test with.).

Uncheck these components on each PC and see of you can 'ping' across to the
other. Cheers!
