Hi all,
Here's the deal. I've installed XP SP2 on a testing machine. Everything went well, nothing seemed to be broken, I can still access the internet via either the network or windows's own PPPoe client.
It's not when I'm unable to connect using my VPN client that I realised SP2 has done something.
Before the application of SP2 I have a L2TP connection to the router at work using preshared key. Everything work fine and I'm happy. After SP2 the connection would time out claiming that "security negotiation has timed out". I monitored the NIC with ethereal and it seemed that all the negotiation is going one way only. From my NIC to the router but no packets are returning (I then suspect windows firewall has something to do with it).
The funny thing is I tried disabling the firewall altogether and still the same problem!!!
I tried swapping out the hdd and load another instance of XP SP1 and recreated those links and 'boom' the VPN works like a charm. Swapped back to the SP2 installation and I get the same time out message, even tried deleting the PPPoE and VPN account and recreating them to no avail
Anyone has any tips on how to get this working?
Thanks in advance.
