Hello,

I have a Windows Server 2003 box running a intranet-vpn setup, basically
joining two LANs of two remote sites. Everything was working great until I
installed Service Pack 1, a client from LAN A cannot ping another client in
LAN B, however they are still able to access resources on both LANs. Not
being able to ping is very annoying, and difficult to trace problems, which
led me into a wild goose chase. <DAM Micro$oft!!>

So my bottom line is, how can I re-enable ICMP without uninstalling SP1 so
clients from LAN A can ping clients in LAN B?

Thanks for any help :)
 
You've got something else going on. All my servers are on SP1 and there are
no ICMP issues across the VPN nor have I ever read of any. Sounds more like
some router jockey read in some article that ICMP is bad and set an ACL to
block it.

The RRAS server on LAN A is SP1 and LAN B has no service pack, could this be
the issue?
