I have set up an IPSec policy that requires traffic from one PC (A) to another (B) use a secure connection (filter set to require security, negotiate security). This policy is applied to PC B.
The result is that no trafiic at all appears to pass between PC's A & B. I am unable to connect to a share on PC B from PC A, and when a ping is attempted I see 'Negotiaiting IP Security' as the 4 ping responses.
I need to get an understanding of how IPSec works before moving on to a larger project, so if anyone can explain why the two XP PC's cannot negotiate security I'd appreciate it.
Also, if you have tips on tools to use to troubleshoot IPSec I'd appreciate it (I'm using the IPSec monitor mmc).
