We have the firewalls all turned off via a GPO. They are off and disabled. FYI, When a GPO policy is put in place turning off the firewall in XP sp2 the "computer browser" service will time out after 5 minutes and stop. Microsoft provides a hotfix patch for this (kb889320). Don't know if this has any bearing on the problem here but I thought I would mention it. We have applied the hotfix to all machines in the forest. I have also applied a registry entry (ole)to all workstations in this OU to insure proper permissions and settings are applied to remote access etc. I have inventoried 180 workstations with 42 never scanned for software or OS.
Here are some of the latest error log entries of some of the workstations. These show up as OK in the scans (Web interface). The 42 others just show errors in the web interface (WMIerror- The RPC Server is unavailable) and do not show up in the error log. Again these 42 check out OK using the connection tester.
