I'm a domain admin in our organisation and local admin on my laptop.
While the laptop is connected at work, there are no issues connecting to other computers, etc.
However, when at home - none of my PCs can access the laptop (ICMP is compltely disabled) and all the options are greyed out - managed by Group Policy.
My collegues are stuck on this one, as am I. I've tried the netsh firewall set opmode disable command without success (output is 'Ok.').
I've had a look in gpedit.msc and can't see anything.
I have the permissions to be able to change the firewall settings for when I'm not in the office - I just lack the methods. OS is Win XP Pro SP2 with most updates (managed by WSUS).
The firewall blocks all 3 of my network adapters, the onboard one that I use for work (DHCP), a PCMCIA card that I use for home (static address), and WiFi (home, work, everwhere else).
