Firewall disabled, but all ports still filtered RRS feed

  • Question

  • Environment: AD domain, XP SP3

    I've got an odd problem here: from the console of this PC I can view all domain resources.  But it is completely inaccessible from the outside.  An attempt to view it reports "network path not found".  I can't ping it, and a network scan reports all ports are filtered.

    I've ensured that File & Print sharing is on.  I've turned the firewall off.  I've ensured that the "server" service is running.  Still nothing.

    Does anyone have any advice?

    Thanks,

  • John,

    I finally figured this out: I ran autoruns.exe and discovered that someone installed Zonealarm on this box at one time, but only partially uninstalled it.  Autoruns revealed the hidden ZA components still running; removing them offline solved the problem.

    I can't recommend autoruns highly enough - it absolutely shows you stuff no other tool does.  My hat's off to Russ and the gang for making this tool available.

    Thanks,

  • How are the IP addressed configured?  Manually or by DHCP?  Are the machines in the same subnet?

  • John,

    IP is assigned by DHCP.  All machines are on the same subnet.  If I run "ipconfig" everything looks OK.

    I swear, it acts just like a firewall is active.  But I've manually stopped the Windows firewall service and it still behaves this way.  I'm stumped.

    Thanks,
