Machine Hangs When Moving from Nortel
Extranet Connection
Reference Number 104298
On a Windows 98 computer, if a user opens a Nortel
Extranet connection, then closes it, then tries to start a
VPN Client tunnel connection, the computer could hang.
A cold reboot is required to recover from this problem.
Selecting Maximum Number of WINS
Tunnels Degrades Performance on NT
Reference Number 6.6-1
During the VPN Client installation on a Windows NT
workstation, you can enter the maximum number of
tunnels for the Client. If you select 4 WINS-capable
tunnels, the performance of the VPN Client is slow.
Absence of VNICs Causes Windows NT
Blue Screen Crash
Reference Number 104100DF
Given a Windows NT system with the VPN Client installed,
if the VNICs (Virtual Network Interface Cards) are not
present, for example, if they have been disabled or deleted,
the next time the VPN Client software is started, the
computer blue screen crashes. To avoid this problem, do
not delete or disable VNICs. Ensure that you have the NT
recovery disks on hand.
If this problem occurs, use your NT recovery disks to
restore your original configuration, or rename your
icvnic.sys file to temporarily disable the VPN Client.
If the system is formatted with NTFS and no recovery disks
are available, you may need to use an NTFS file rename
utility, such as NTFSDOS Tools, available from
sysinternals. Using your browser software, go to the
