hi

we have managed to come across a lovely issue with sophos and the netscreen vpn software.  Essentially from what we can make out (since the update sophos has release over past 2x days) is that their new and improved AV/ Fwall software is now updating the drivers for the virtual network adapter under device manager on our client machines.

Has anyone else come across this problem?!?!!?!?!?!??!?

Thx

Can't remember, but if NetScreen Remote uses Deterministic Network Enhancer, that is used by several VPN clients. However, it is a bit strange that Sophos can't keep its fingers out of that business.

But why is it an issue at all?

You can try different versions of the Deterministic Network Enhancer (see http://www.citrix.com/lang/English/lp/lp_1680845.asp), or use another VPN client (like the free ShrewSoft VPN, www.shrew.net).

maybe.  the point is that their software has screwed our VPN and essentially their support (what we pay for) is crap.
We are not uninstalling the firewall and installing zone alarm!

Found that the latest version (compatible with XP) of the netscreen software wotks fine with sofphos firewall.  problem caused by sophos and the older version of netscreen vpn software.

Now looking at moving away from sophos next year as support is shocking.
