Is 10.10.1.1 the fa0/1 address on the server? Is 10.10.2.2 the loop back address on the client?

Yes.
10.10.1.1 F0/1 Server
10.10.2.2 Lo0 Client
05-26-2012 06:32 PM
access-list 10 permit 10.10.2.2
Let's keep it nice and simple first. Get rid of this line temporarily.
ntp master 5
Get rid of this. Cisco don't recommend using this command

I did that without the access-list no luck, did do it with the master 5 thou, but its a requirement to do Stratum 5!
i'll try it after the weekend thou.
thx Leo.
