Premature VPN Disconnect following latest 10.3.9 Security Upgrade

Question

The only known change to my off-site iMac G3 running 10.3.9 is the latest security "fix" for 10.3.9. Noticeable following that change is my all-too-frequent loss of connection to my employer's intranet via CISCO Systems' VPN.
Other than somehow reverting to a prior configuration, is there a recognized work-around enabling a more robust connection?
In a previous Posting, I had inquired about upgrading my iMac to 10.4, but the indications are that 10.4 does not run as well on the G3 as 10.3.9.
Thanx in advance for any assistance,

Answer 1

I am not positive, that this is your answer,
Many users after updateing there system report the lost funtion of different Applications as well as printers, scanners, and various programs.
As a rule VPN's require software or special treatment.

Many security updates will automaticly change some settings to a default setting that require you to re download, or seek the applications update or upgrade from the manufacture's site as well.
Much depends on the type of VPN, not the Manufacture
for the most part it is determined by the particular protocal used by your system administrator.
You will prbably have to re-confiqure your connection.
