Attached are latest configs for each side. The IPSEC VPN is working between locations. 1841 router is HQ and has a Windows Small Business Server 10.2.1.6 that hosts MS Exchange & DNS for the domain. Remote site (PIX) need to access servers at HQ by name, workstations have their DNS pointed to 10.2.1.6, but get no DNS replies from that server. Something is not properly crossing the VPN, or some ACL is blocking. From remote (PIX) side I can ping HQ devices by IP number but not by name. Nor can I access https://10.2.1.6/exchange for OWA. Something not routing properly.
