One comp pings the other but cannot share files

[BigG3522]

I have a corporate laptop that I use for work, and a home network running off a dlink router. Now I remember just simply plugging my corporate laptop into my network and copying MP3's onto it the first day I got it. Now, I can't connect to it anymore from either computer. Both computers can access the internet, the corporate laptop has all the ICMP checks marked off in the windows firewall (as I can't disable it as per security policy) and the others don't have windows firewall enabled at all. The home computer can ping and connect to all other computers except the corporate laptop, and the corporate laptop can only ping my home computers but can't connect to them. I have a 1 way traffic it seams like. I removed all VPN software and can't get her to work. Any idea's?

Because ping works on Echoing responses back to your machine then there MUST be two way communication occuring.

Also, because you are getting a response then the Laptop is on the same Subnet.

Is it in the same workgroup or domain?

This sounds more like an AD issue of some sort.

Have you got file and print sharing allowed on the corporate?

 

[BigG3522]

Sharing is enabled on both. And Yes the laptop is on my work domain, but that's never been an issue before. Computers on domain's were still able to access my home network computers. It pulls an IP address fine. But on my home computer I cannot ping the corporate. The corporate can ping everything. Settings in the corporate allow pinging. What is an AD issue?

Just a long shot but your home network isn't using the same internal ip range is it? i.e. your work = 192.168.0.x and home 192.168.0.x?

That would cause this sort of problem.

Also are you running any firewall hardware / software?

AD = Active Directory

actually you won't believe this, but I pulled it off the domain, and rejoined it to the same domain, started it up and logged on and off a few times, and the problem went away. I can't explain it.
