To all-

Question-
Is it possible to switch out the TCP stack or the networking files updated
with SP2 for the ones present in SP1?

Issue-
On Win 98, 2k, and XPSP1, the IPSec VPN client SSH Sentinel worked very
well. The client is feature rich and has a diagnostic "ping" which helps
resolve connection failures. On installation, it creates a "virtual NIC
adapter" with its own MAC and interface # which can be seen with ipconfig
/all. When operated in Tunnel mode to a VPN gateway, this virtual adapter
is *manually* given a virtual IP # which allows it to browse the remote
network, with
all traffic directed to that network going out that "virtual" adapter.

Unfortunately, Sentinel is no longer supported.

XPSP2 breaks the virtual adapter and allows no traffic to go out it or for
it to be assigned a virtual IP#, rendering Tunnel mode inoperative.
Transport mode to a separate host is still functioning.

Done so far.-

Using DLL watchers , Process Monitors, and Dependency Walkers... all point
to
various files being loaded, but trying a few has not worked. Switching
TCPIP.sys , TDTCP.sys and NDIS.sys also do not work.

Since this install is an upgrade, many files are in Windows\oldsystem32 or
Windows\oldsystem32\drivers

SP1 file version numbers are 5.1.2600
SP2 file version numbers are 5.1.2600.2180

So is it possible to revert to the networking functions of SP1 while
retaining the other features of SP2?

Many thanks-
