pc Extremelly slow connection from a external domain clients

[ennov]

We have FMS11 installed in a 2003 server under a local domain. We have installed FMP11 in 50 computers working remotelly from different locations. All of them are connecting fine except a group of 8 Win7 PCs that are connected through a local domain on a Windows 2008 server. They can see the list of Databases but when they want to open any of them it takes at least 30 minutes to just open it. Obviously, the navigation through it is impossible slow. We did connect from a PC out of the domain but in the same network and it worked fine. We are assuming that the problem is somewhere in the domain policies or configuration. According to the local administrator all the required ports are not been filtered nor closed in the domain policies (see attached) or firewall, but we just do not know where else to search. Any suggestion/ideas will be appreciated. Thanks.

Start with a trace route analysis from one of those domain computers and compare it to the same of the non-domain computer on that network.  It's clear that one of the hops on the route for the domain computers is holding up traffic.

 

Are they both using the same segment of the network?  Is the traffic going through the same switches on its way out?
