(I searched this ng but did not find any information to help me. If I
missed a relevant post in this ng or another, please direct me there, thank
you.)

I installed SP2 a week ago from stand-alone offline install file (270meg).
XP Professional SP1 base systems (two of them). No problems installing SP2,
installation was smooth and normal.

All has been working fine with both machines and I am quite happy with the
enhancements to applications such as IE and Outlook Express.

Today I needed to access my employer's private network via VPN connection.
This was previously working fine under SP1. Under SP2, VPN appears to
connect normally and successfully, I do not see anything unusual there, no
error messages, send and receive bytes are about right for initial logon. I
am assigned an IP on my employer's network, a network admin there can see
the IP as having been assigned to my machine.

But my machine cannot access any resources on the remote network, and does
not respond to any pings, etc. When I attempt to do a tracert or ping to
one of the resources on the remote network, the host name cannot be
resolved. If I try with IP address instead of host name, all attempts time
out with no success. The VPN icon in systray never 'lights up' again, and
the byte count (sending and receiving) never increases after the initial
logon.

I re-verified XP firewall is still turned off in network properties. Opening
Network Connections folder does not show 'firewalled' next to any
connections (LAN, VPN are the only two).

I do not see that anything has changed on my VPN settings. I tried this
with both machines and the results were identical.

In deperation I uninstalled SP2 from one of the machines. VPN is working
fine again on that machine.

Any ideas? TIA for any help.

Thanks,
