I have still an issue with a couple of desktops not been scanned due to RPC errors (The RPC server is unavailable 0x800706BA). I have installed SP3 on both of them but still the problem will not go away.
all clients get serviced by a DHCP server with the lease period of three (3) days.
a) from the computer which has the issue, I can ping the following
loopback card and it respons
the computer by name
the computer by ip
the gateway
a internet name server e.g. ns.sun.com and all works fine.
from the Domain controller,
running arp -a show the computer mac address but pinging to the computer either with a name or ip address does not respond.
The firewall on the computer (does allow file and printing as well as DCOM on TCP port 135).
