PIX service groups

[mikelehnert]

I created a service group for access to our internal DNS servers and it didnt work. I created a service group using the tcp-udp choice. I added Domain. used it in an access list and it didnt work.
I created 2 seperate access lists not using a service group and it worked fine. I created 1 list that allows tcp Domain and 1 list that aloows udp Domain.
I like the idea of using service groups but need to know what i am doing wrong.
Thanks
