I have an odd situation with my laptop...

I am trying to test some software that has 2 components. Part1 is on another machine on the network and connect to Part2 which runs on my machine.

Trouble is, my machine is not visible on the network! I can Ping other machines on the network but if they try to ping me, they get a timeout.

This used to work fine, it is not a new laptop & I don't think I have changed anything (classic user statement!)


Running Windows XP. Not running the Windows firewall (or in fact any firewall! Relying on the office one). I will have a look at the Windows firewall settings though.

enguerran: Yes, you are right, something must have changed but I am not aware of having changed anything.

I am on the same domain. I am not runnig a firewall. I did change my password today!

The other machines are able to obtain my IP address from my hostname and it matches what my machine thinks its address is. But the ping message itself times out.

Here is the output of TaskList:

Anything in there that leaps out? Or any other commands that I can try? Unfortunately our IT department is heavily overworked and does not return his calls!

This is most likely to be a firewall issue. Most Windows firewall setups that have not been tweak from the defaults are set to stop ping responses or any other remotely accessible such as file sharing.

I have seen the Windows firewall revert back to default settings after certain service pack or security update installations, so even if this all worked before it is worth verifying the settings are as you expect them to be.

The other issue to look out for if you are running Vista or Server2008 is to check in the "network and sharing centre" to make sure your network hasn't been changed to "public" where is was once designated "private" - this would also explain a change in firewall behaviour, and is not uncommon to see happen as you move a laptop from one network to another.

DHCP and IP address change, I suspect.

Thanks for all the suggestions.

It was to do with policies.

I had stopped the CheckPoint VPN1 Secure Client software we run for remote connections, since I thought that had previously fixed the issue. Unfortunately, that was not actually what I had previously done.

What I actually needed to do was use the Checkpoint VPN Client to Disable the Security Policy. It now works, my machine can be contacted and I have updated my notes.

Sorry for bothering you guys and thanks for the suggestions.

Can somebody mark this as 'Answered'. I don't appear to have the ability!

Check both firewalls if they are enabled or not.

Regarding the OS, you can enable/disable the ping answer with the built-in firewall. Network issues depends on your OS and your installed softwares: if you can specify those information it will be welcomed.

Could you tell us the network architecture of yours?

Tips:

I don't think I have changed anything

but something has changed or

This used to work fine

it didn't.

I don't seem to be able to edit the question so...

Running Windows XP. Not running the Windows firewall (or in fact any firewall! Relying on the office one). I will have a look at the Windows firewall settings though.

enguerran: Yes, you are right, something must have changed but I am not aware of having changed anything.

I am on the same domain. I am not runnig a firewall. I did change my password today!

The other machines are able to obtain my IP address from my hostname and it matches what my machine thinks its address is. But the ping message itself times out.
