joining computers to domain with asa firewall in place

[tshwaragano]

I have an ASA firewall (inside interface ip=10.15.15.1 and outside int=192.168.3.1). DNS server is seating on the inside of the ASA. All PCs inside are able to join to domain but the ones outside of ASA are refusing to join to domain. The PC's can access internet and ping the domain from inside and outside but can't join in to the domain. Have I missed anything?

Domain controller(10.15.15.3)------(inside int =10.15.15.1)ASA(outside=192.168.3.1)------internet------pc2(fails to join to domain but can ping the ip for domain)

Hi tshwaragano, 

It looks like it might be an application issue, I would rather place a capture on the ASA or server to check the communication between the outside host and the domain controller.

Hope it helps
